ABSTRACT
The results of experimental studies of the dependence of the thickness of amorphous-crystalline Zr-Al-B coatings on the value and level of distribution of residual stresses of type 1 are presented. Was demonstrated that residual compressive stresses arise in the surface layers of coatings, which in absolute value are not significant for its integrity and quality. It is established that the amorphous-crystalline composition, in conditions of minimizing residual stresses and the optimal combination of the volume fraction of components, the structure and morphology of their components, has the best surface strength and wear resistance under friction compared to tungsten carbide and iron coatings
