СHARACTERIZATION OF ARC-PVD ZrN NANOSTRUCTURED COATINGS BY USING THE FRACTALS THEORY

Abstract

Nanostructured ZrN coatings for hardening of a thin-walled cutting tools operating under cyclic loads conditions have been obtained and investigated. The structure and mechanical properties of nanocoatings have been examined. It was revealed that the ZrN coating improved the properties of thin-walled cutting tools. ZrN surface morphology was theoretically substantiated with the application of the fractals theory.
