Aluminum alloys are widely used in vehicle castings, but the alloys are easily oxidized in the air and lose their performance. Anodizing treatment is utilized to solve this problem in industry. Aluminum alloy with high Si content usually hasn’t luxurious colors for conventional anodizing treated oxide film. Therefore, it is worthy to study the method of producing special luxurious colors of appearance on the aluminum alloy with high Si content by electrolytic coloring anodizing treatment. The anodized oxide film will retain high hardness and increase added value through the optimal electrolytic coloring anodizing treatment found in this study. A390 aluminum alloy which has high Si content was used to cast the stepped type casting and vehicle piston casting in this study. The electrolytic coloring anodizing treatment used H2SO4, CuSO4 and Fe2(SO4) as the solution to anodize the castings. The parameters studied in this experiment include casting thickness, current density and electrolytic coloring anodizing time. The effect of these parameters on the oxide film will be evaluated to establish the optimal conditions of electrolytic coloring anodizing treatment for A390 aluminum alloy castings. The results of this study show that the thick section of A390 aluminum stepped type casting had the largest thickness of electrolytic coloring oxide film compared to those films formed on the thin and medium sections in stepped type casting. The reasons are related to the grain size of primary aluminum. In addition, the growth rate of oxide film formed on A390 aluminum casting by electrolytic coloring anodizing film will be inhibited when the film grew to contact with primary Si particles beneath the substrate. Finally, the scalloped substrate will be formed due to the envelopment of primary Si particles in the oxide film. The thickness of electrolytic coloring anodizing film of A390 aluminum stepped type casting increases with the increase of electrolytic coloring time, but it’s hardness decreases with the time. The reason may be related to the gel layer deposited at the bottom of porous layer of oxide film. The condition to achieve maximum thickness of the oxide film is 3.9 A/dm2 current density and 65 minutes electrolytic coloring time, while the condition to achieve maximum hardness of oxide film is 1.3 A/dm2 current density and 15 minutes electrolytic coloring time. The optimal condition for the thick section of A390 aluminum stepped type casting to produce bright yellowish color of electrolytic coloring anodizing film by using H2SO4, CuSO4 and Fe2(SO4) mixed-acid solution is 2.6 A/dm2 current density and 27.5 minutes electrolytic coloring time, but for the thin and medium sections, the optimal condition to obtain the same color is 2.6 A/dm2 current density and 15 minutes electrolytic coloring time. Using the optimal conditions mentioned above to electrolytic coloring the A390 aluminum alloy pistons, it is found that the color of oxide film of small piston is dark reddish yellow, while the color of oxide film of large piston is dark blue-gray. It’s worthy to say that the colors of oxide films of pistons are different from those colors of oxide films on the stepped type castings. The causes of this difference are related to the grains at the chill zone of superficial layer on the pistons and whether the surface of pistons are machined.

The effect of the step of electropolishing before anodic oxidation on the properties of aluminum oxide film were investigated in this study. It is expected that the addition of “electropolishing” before anodizing step can obtain a better anodic film and colored film. The experimental results show that the electropolished aluminum sheet increase the number of pores of the anodic film. And make the pores more uniform and more orderly. If electropolishing is used, the △E* value and reflectivity of the colored film are lower than without electropolishing. From corrosion test, the corrosion resistance is in the following order : (Aluminum sheet after EP) < (aluminum sheet with no EP) < (anodic film with EP) < (anodic film with no EP) < (colored film with no EP) < (colored film with EP). The optimal operating conditions for obtaining the blackest colored film are: electropolishing voltage 10Vdc, electropolishing time 30 min, anodizing current density 2A/dm2, electrolytic coloring voltage 20Vac and electrolytic coloring time 30 minutes, the lower △E value, corrosion rate and

In this research, the effects of pore- widening time on the physical properties anodic films and colored films are investigated. It is expected that suitable pore sizes can be obtained on the alumina film by the step of pore-widening in phosphoric acid. And the best operating conditions for depositing silver ions in the pores of the anodic films are found out. It is found that, when the pore-widening time increase, anodic film thickness become thinner but pore diameter become larger, as well as hardness and gloss decrease. After electrolytic coloring, the pore-widened alumina films have low L value, gloss and reflectivity, which is lower than the films before pore-widening. The increasing of pore-widening time, electrolytic coloring time and voltage will decrease the film hardness. The corrosion test can prove that the corrosion resistance of the anodic films would be improved by electrolytic coloring. From EDS, it can find that more Ag ions can be deposited in the pores of the pore-widened anodic films. The operating conditions to obtain the blackest anodic film in this experiment are: pore-widening time 2 minutes, electrolytic coloring voltage 20VAC and coloring time 20 minutes. The colored film has the following physical properties: the lowest ΔE value of 10.30, the hardness of 523Hv, the gloss of 16.1, the thickness of 12.6μm and the reflectivity of 6.16% at the visible light wavelength.

This study was carried out by means of the method of twice anodic treatment in the sulfuric acid and then electrolytic coloring in cupric sulfate solution. The effects of the first and second anodic treatment on the properties of the anodic films and colored films would be discussed. For the second anodic treatment, the film thickness of the anodic film is thicker than that from the first anodic treatment. But the hardness is lower than that from the first anodic treatment. Whether the first or second anodic treatment is done or not, the film thickness of the anodic films is almost not changed after the electrolytic coloring, however, the hardness decreases with the coloring times. As for the color difference of colored film, the L value from the second anodic treatment is lower than the first anodic treatment. Under the coloring voltage of 20 V, the L value of colored film from the second anodic treatment is approximately 10 and the a and b values approach to zero and hence the darkest shade of black color can be reached. From the film dissolution test and SEM, the anodic film from the second anodic treatment has the more porous and looser structure, it is suitable for coloring. From the observation of AFM, the anodic film surface from the second anodic treatment is even and the pores are enlarged. At the range of the visible light wavelength, the reflectivities of colored film from the second anodic treatment are all lower than those from the first treatment.

This research is to investigate the effect of the annealing conditions on the physical properties of the anodic oxide film and colored film. It is expected that by taking the advantages of annealing, a better aluminum oxide layer can be obtained to proceed the electrolytic coloring for getting a black film. By the way, to find the optimum operation conditions to obtain the darkest shade of black anodic film on aluminum. Specimen of the annealed aluminum was investigated after anodizing in sulfuric acid solution and then electrolytic coloring in silver nitrate solution. The microstructure, microhardness, thickness, chromatism and chemistry elements of anodic oxide film were studied by using scanning electron microscopy (SEM), microhardness tester, electronic thickness tester, spectrophotometer and energy dispersive spectroscopy (EDS). It is found that after the annealing treatment at given temperature and time, because of the rearrangement of the surface crystalline structure, the growth condition of the anodic film can be improved. From the analysis of X-ray diffraction and the observation of SEM, it is known that the crystalline produced after the annealing is γ-Al2O3, and the structures of the pores are larger. Therefore, the anodic oxide film from annealing would be helpful for the electrolytic coloring in the silver nitrate solution, hence the lowest L-value of 10.32 and the minimum reflectivity of 5.54 % were obtained. To obtain the better black film on aluminum, the best operating conditions are as follows: annealing temperature of 500 ℃ for 2hr, anodic current density of 2 A/dm2 at bath temperature of 20 ℃.

As compared to conventional anodizing processes, micro-arc oxidation (MAO) can be used to prepare ceramic oxide films with higher hardness, excellent corrosion resistance, and favorable ceramic texture. However, limited color for the as-prepared MAO layer have restricted its application in many cases, especially consumer electronic products. A coloration method applied to MAO layer while retaining its ceramic surface texture shall significantly add the value of the existing MAO technique. An innovative post-dyeing treatment for MAO treated aluminum alloy was developed in this study. This begins with a cathodic treatment of MAO treated aluminum alloy in a NaCl solution at 20-30 V, followed by anodic dyeing with a constant current of 1 A in an anionic dyeing solution. Based on microscopic analysis and observations, the chiseled micropores created during the cathodic treatment allowed the anionic dyes to adsorb onto the MAO layer during anodic dyeing, thus making the MAO layer dyeable. High color saturation can be achieved after the colored MAO sample. The chromaticity value obtained using a commercial blue dye is (L * a * b *) = (53.55, 1.17, -29.16), while it is (75.93, -2.59, 35.63) and (65.54, 24.05, 11.32), respectively when using commercial green and red dyes.

In this research, using twice anodization on aluminum and adding citric acid in an anodizing electrolyte simultaneously is the purpose to obtain a better pore structure than the process of once anodization. And the best operating conditions to obtain a blacker anodic film using electrolytic coloring solution of CuSO4 or AgNO3 had been found out. The experimental results show that, the larger and more orderly pores structure after the second anodization are obtained. Using the second anodization brfore the process of electrolytic coloring has many benefits to the properties of the colored film than using the first anodization, like film thickness, chromatism, reflectivity and anticorrosion. Electrolytic coloring in AgNO3 solution has the advantage of short reaction time and lower operating voltage to obtain blacker film than coloring in CuSO4 solution. The best operating conditions to obtain the blackest film are：the second anodizing current density of 2A/dm2 , the electrolytic coloring voltage of 25V in CuSO4 and coloring time of 30 min, it has a △E* value of 8.39; For the electrolytic coloring solution in AgNO3, the coloring voltage of 25V and coloring time of 20 min are the best operating conditions to obtain the blackest film with △E* value of 7.76.
