The application of coatings can be found in engineering components, cutting tools and forming and in special instruments. Industrial sectors in wich such improvement are utilized include the automotive, aircraft and other transportation industries, the electronics and metal industry as well as the sector producing machinery for the chemical, food and other process industries, military equipments, equipments of instrument outside space, even recently the growth are of coating applications is in biomedical components and others. The main purpose of coatings are used to reduce wear and protect the substrate from wear, increasing component life times, increasing the fungsional and performance of tools, reduce friction and to minimilized production cost. This final project present the result of finite element analysis (FEA) which is used to simulate three-dimentional (3D) sliding contact. This research was conducted in case of single coating and multilayered ellipsoids from gradient, sandwich and the selected multilayer coatings with various preset vertical interferences, materials and thickness of coatings and then sliding across each other with both no imposed friction coefficient imposed and a coefficient of 0,3 imposed. A finite element analysis (FEA) is used for modeling and getting the result to investigate including the von Mises stresses, contact areas, shear stress at each coatings and that influence of substrate as a function of sliding distance. Contour plot of the von Mises stresses are presented to show the distribution of stresses with increasing plastic deformation as sliding distance progresses. It is found that vii comparation of present model with model from other researcher shown very good with error less than 2 % and the graph result are coincide with the others.
