The use of micrometer thick coatings in tribosystems now is of increasing interest in the area of mechanical engineering to reduce friction and wear. This work was initiated to analyse critically the deformation of electrodeposited Co-W and Fe-W coatings resulting from indentation tests, and to identify the microscopic features of the surfaces of such electrodeposited layers. On other hand, the present work focuses on an improved understanding of the plastic deformation field of the indentation made in thin layer deposited on a substrate, especially the mechanisms formation of the pile-ups around the indenter.
