| Summary: | Multilayer coatings represent a promising class of protective coatings due to the improvement in tribological, mechanical, and anticorrosive properties conferred to the coated surfaces. This has motivated the research, development and implementation of these materials in many industrial applications; nowadays the requirements of the industry are not satisfied with materials that have a good property, but a combination of good properties for most of the applications. In this work CrN/TiN multilayer coatings were deposited by magnetron sputtering; the variation of number of coating bilayers with 4 μm total thickness was of 10, 40, 80 and 100. The grain size and the roughness of coatings were determined by means of atomic force microscopy; micro hardness and scratch adhesion tests were performed, the friction coefficients were evaluated in a ball on disk tribometer, and the abrasive wear resistance was determined by Calotest method. for the sample with 10 bilayers to 29.8 GPa for the sample with CrN / TiN 100 bilayers..
