The article by computer simulation investigated the distribution of temperature and stress-strain state of composite materials and coatings at all stages of their life cycle. Determined the distribution of transient temperature fields, stresses and strains that occur in composite materials and coatings in the process of forming and friction and wear , as well as local areas with a maximum difference of temperature and stress and the impact on their internal and external factors. Computer simulation of composite materials and composite coatings made it possible to construct a non-stationary heat field and thermal stress field in composite materials and composite coatings with dispersion - strengthened and eutectic types of structures that arise from stationary sources of heat ( of friction ). It is shown that the configuration of these fields are essentially uniform, there are significant changes in temperature and stress due to heterogeneity of structure heterogeneity thermophysical and mechanical properties of the structural components of composite materials and composite coatings that achieve , depending on the load of friction , melting components, and local stress - up to several GPa. The value of tensile stress and compressive alternating throughout the volume of the composite material and composite coatings. There is a close relationship between the structure of composite materials and composite coatings, the size and shape of structural components and statistical and local values of temperature and stress appropriate nonstationary fields. To minimize temperature changes and thermal stresses to use uniform size structure of the filler with a maximum dispersion of carbides and align the thermal properties of filler and matrix, which must provide high relaxation ability. According to the results of computer simulation can optimize the composition and structure of composite materials and coatings to enhance their physical and mechanical characteristics and tribotechnical.
