Abstract
MATHEMATICAL MODELING OF STEPS OF THE SURFACE LOAD OF DETAILS IN DEPENDENCE FROM LOAD MODES Chernet O.G., Sukhomlin V.I., Voloshchuk R.G. Abstract Methods of obtaining wear-resistant coatings are considered in this work, and mathematical modeling of the degree of wear of a surface layer is carried out, depending on the modes of combined loads. The graphic dependences of the intensity of wear on the surface layer of the component are obtained depending on the hardness, speed, combined loading modes and the period of tribological exams. An analysis of the transformation of the structure of wear-resistant layers from steel 45 is carried out depending on the technological methods and physical and mechanical properties of the working surfaces, which are given in photographs with microstructures of the corresponding layers of the working surface. Also graphic dependences of microhardness of the corresponding areas of working surfaces are given. Sufficiency of the estimation of the average general accumulation can be described with the help of quantiles normalizing normal distribution . The experiment investigates - the mass loss of material in the process of wear (X). The wear process is affected by the microhardness of the coating material (X1), the contact pressure P (X2), the velocity of the sample V (X3) and the wear time (X4).
