The physical model of changes setting in multilayer bearings

This work presents the physical model of changes setting in multilayer bearing of combustion engines. It is known, that the slide bearing of high-load combustion engines independently from manufacturing technology, must have a material stability with regard on diffusion process of the alloy components. The present state of materials used on slide multilayer bearings of combustion engines has not changed during the last 30-year. Only small changes and modifications of material multilayer bearings, with the use of the same groups of materials, independently from specific manufacturing technology of bearing and their use were observed. The change of bearings materials. growth of operating requirements of combustion engines, ecological limitation and the price of materials may force changes in present constructional and technological conception of multilayer, in range of materials selection and huilding the bearings. This work presents the physical model of changes setting in multilaver bearing on different building. U was found that the slide bearing of high-load combustion engines is not physically and thermally stable up to l80 centigrade. Different models show that after heating, all phases and structural components present on graph of equilibrium in given temperature are not created.
