Abstract:

Microstructural observations are presented for different metals deformed from low to high strain by both traditional and new metal working processes. It is shown that deformation induced dislocation structures can be interpreted and analyzed within a common framework of grain subdivision on a finer and finer scale down to the nanometer dimension, which can be reached at ultrahigh strains. It is demonstrated that classical materials science and engineering principles apply from the largest to the smallest structural scale but also that new and unexpected structures and properties characterize metals with structures on the scale from about 10 nm to 1 μm.

Abstract:

Parts subject to intense abrasive wear have a short service life. In the manufacture or restoration of such parts by electroslag surfacing, strengthening of the deposited metal is required. The use of ready-made alloying powders in surfacing increases the cost of the finished part, which necessitates the search for cheaper materials for alloying the parts being welded. The study of the efficiency of alloying the deposited metal through the melted insert, as well as by direct introduction of alloying powders into the slag bath has been carried out. Mixtures based on enriched mineral scheelite concentrate and graphite are used as alloying powders

Abstract:

For the realization of efficient production processes, an understanding of the appropriate application of metal working fluids (MWF) is necessary. In addition to knowledge about the process-related aspect of chip transport and the macroscopic cooling effect, the characteristics and properties of the lubrication film thickness and the cooling conditions in the area of the secondary shear zone on the chip surface, i.e. in the direct vicinity of the material separation, represent a fundamental scientific issue within production technology. In particular, these areas generate a high proportion of heat during machining, so that the local friction phenomena have a significant influence on the resulting edge zone of the produced component and the thermomechanical load on the tool. Currently, there are no numerical models and methods for mapping and predicting the lubrication film thickness that can be used in the sense of a targeted design of the cooling lubricant supply. The aim is to transfer the methods from the field of tribology of machine elements, which have already led to significant knowledge gains in this discipline, to machining and couple them to approaches already established in machining. To this end, experiments on tribometers have been performed as a first step. For example, an oscillating pin-on-plate tribometer was used. In this setup, a steel plate is doing oscillating motion against a fixed ball (diameter of 6 mm) under a defined load. The frictional force is recorded during the test. A MWF in a heated tank is used for the lubricant. Additional investigations on the film thickness were performed on an optical EHL (elasto-hydrodynamic lubrication) tribometer. In this setup, a ball rolls on a glass-disc and the resulting film thickness is measured by interferometry.For comparison, the influence of the MWF on the chip formation process in metal cutting was investigated on a special test rig (machine tool). This test rig allows high speed imaging and force measurements of an orthogonal cutting process while using MWFs. The first results show a reduced contact length between chip and tool as well as lower process forces for processes with MWFs compared to dry cutting processes. In future investigations, this test rig will be applied for the identification of the local friction coefficient between chip and tool. The data gained from the cutting test are compared with the output of the tribological test rigs.

Abstract:

When two identical penny shaped disks mounted one above the other are upset simultaneously in uniaxial compression, they deform differently if friction on the upper die surface may be covered by a thin film of teflon which results in essentially zero friction there while the lower die surface corresponds to a lubricant-die material-work material combination to be evaluated. After deformation, the thickness of the upper disk at its center (h1) will be less than the central thickness of the lower disk (h2) if friction on the lower die surface is greater than on the upper die surface. The ratio h1/h2 provides a sensitive measure of the difference in frictional resistance on the upper and lower die surfaces and may be used to evaluate different lubricant-die material-work material-die finish combinations for different degrees of reduction. Representative experimental results are presented and discussed.

Abstract:

Most of the several billion liters of metalworking fluid (MWF) used worldwide and annually are water-based and thus prone to a microbial contamination. The microbial growth leads to a deterioration and therefore to a loss of quality and technical performance. In most cases, biocides, which pose a potential risk to health and environment, are used to reduce the microbial load. To avoid these limitations, the paradigm shift of using microorganisms in a positive way in a manufacturing process as a lubricant is investigated in this paper. Some microorganisms are able to synthesize equivalent MWF components like e.g. fatty acids or sulfur compounds. Due to this fact, it is possible to create a regenerative system on a microbiological basis for the substitution of mineral oil containing MWF components. To demonstrate the lubrication potential of bacteria, preliminary investigations were conducted on a Brugger-tribotester. Against this background, the approach presented here intends to investigate the lubrication properties of special microorganisms and the influence of the microbial cell counts on the lubrication behavior respectively. The results of the tribological tests show that the microbial-suspensions exhibit Brugger-values as high as highly concentrated conventional MWF and indicate the potential to replace these respective components.

Abstract:

Carrying out of the clearing operations at carrying out mechanized processing of construction equipment from paints and varnishes, rust, various kinds of pollution belongs to mass labour-consuming operations [1]. To carry out these operations, widespread use of hand-held machines, working bodies that have abrasive wheels and metal brushes. The versatility and versatility of these machines, combined with the correct selection of the desired abrasive work tool, can significantly accelerate and facilitate the performance of cleaning and grinding operations with the desired effect. However, most of them have drawbacks in the cleaning of thin-sheet metal, since the removal of the base metal also takes place, which in most cases is not acceptable. So when processing non-metallic materials with metal brushes the working surface is clogged with small particles of metal, which subsequently leads to the formation of rust, and when cleaning the metal surfaces grooves are formed. Metal brushes are also ineffective in cleaning surfaces of synthetic enamels, curvilinear surfaces and inaccessible areas. Machining these tools is energy-intensive and requires the use of heavy-duty hand machines. Fiber and petal abrasive tools are not self-cleaning and lose their cutting power due to the filling of the intergranular space with cleaning waste. Sand blasting is environmentally hazardous for workers and the environment, since the sand consumables fly over long enough distances (especially when clearing tall structures and structures). The analysis showed that one of the effective tools for cleaning metal and non-metal surfaces from paint coatings, rust and other contaminants without removing the base material layer is a polymer-abrasive brush. However, there is insufficient research on the mechanism of its operation, energy and thermal processes that occur during operation and have a decisive influence on the performance of the polymer-abrasive brush. The results of studies of the influence of structural and mode parameters of manual angle grinders with polymer-abrasive brushes are presented in the paper. The study of these issues is an urgent task, as it will allow to determine the parameters of the drive machine, rational modes and schemes of their operation, as well as the scope of use of such working bodies.
