| Abstract | The evaluation of tribological properties of PVD multi- and nanocomposite coatings on the PM substrate Bohler S390 is presented. Tribological properties were evaluated by the ball-on-disc test and by metallographical analysis of the wear track after testing at room temperature. Coefficient of friction and specific wear rates were evaluated. Damage mechanisms were identified and their relationship with structural characteristics was inferred. PVD technology is among the modern ways of depositing thin coatings onto the surfaces of machine parts. Technological methods of deposition process of thin coatings are constantly innovated. At the same time, new types of coatings are being developed. The evaluation of structure, composition and properties of coatings is necessarily all development time. An AlTiNmulti and nanocomposite nACo (TiAlSiN) coatings are used to increase the service-life of cutting tools. Because of this, it is important to analyse the behaviour of coated materials in a tribological environment. |
