Shiganov I. N., Misyurov A. I., Smirnova N. A., Usov S. V. — Increase of mechanical characteristics of titanium alloy VT3-1 by local laser impact treatment

The paper discusses the effect of local laser treatment of Titus is a new alloy on the mechanical properties of the material and welded joints. To study the variation of hardness of the machined surface of titanium alloy VT3-1, depending on the processing parameters of pulsed laser radiation. It is shown that if the surface heat treatment the hardness can be increased relative to the base material 2—3 times. To reduce the content material of titanium nitride it is necessary to apply protection treatment zone with argon.
Application of laser shock wave treatment also increases surface hardness, but it creates compressive stresses on the surface of the part, which can favorably affect the fatigue characteristics.

METHODS OF CONTROL AND DIAGNOSTICS

Petrishin A. V. — On the industrial application of energy dispersive roentgen fluorescent analyzers

Energy dispersive X-ray fluorescence analysis (ED XRF] enables the qualitative and quantitative elemental material composition to be determined, as well as thicknesses of multilayer coatings to be measured. Nowadays this method has been implemented in modern equipment, which is widely used both in laboratory measurements and in industry.
The article describes the basic principles of the method and gives an overview of its different applications. Special attention is paid to the following industrial applications: thickness measurement of immersion gold on circuit boards; thickness measurement and composition of electroless Nickel; thickness measurements of electroplated measurements of silicate coatings; measurements of turbine blade heat-resistant coatings.
Experimental research was carried out; measurements were made with the FISCHERSCOPE X-RAY analyzer manufactured by the company "HELMUT FISCHER GmbH" [Germany). The experimental results for different samples are presented as well as the ways of solving the arising problems. The ED XRF method has proven to be highly efficient for abovementioned industrial applications. The growth of scientific and technological progress is creating new possibilities for wider application of the ED XRF method including problems of non-destructive testing.
Key words: X-ray fluorescence analysis, elemental composition, multilayer coating, coating thickness

MATHEMATICAL MODELING, NUMERICAL METHODS, PROGRAM COMPLEXES

Pereladov A. B. — Study of the abrasive process indicators through the use of a 3-dimensional computer model

The article describes the research of grinding process indices on the basis of the developed computer model executed in the engineering 3D CAD of T-Flex CAD. Through the use of the grinding process simulation results, it became possible to determine the statistical indices of the microcutting process (the statistical distribution of the chips sections areas cut off by single abrasive grain) and to create the power statistical-probabilistic model of the tool work. This model permits to predicts one or another wear rate (dulling, self-sharpening, shedding) with taking into account the static indices of the grinding wheel structure — the strength of grain retention on its working surface. The scientific novelty of the work lies in the fact that new experimental results have been obtained, which allow to evaluate the tool efficiency, the interdependence tool characteristics, the grinding conditions, the properties of the ground material. The results of the research will be used to improve the method for designing diamond-abrasive treatment, which allows to automate the calculation of the grinding tool optimum characteristics and its application modes at specific materials treatment.
Key words: grinding, computer model, chip cross-section, cutting force, statistical distribution
