Elastic-Plastic Analysis of Rolling Contact for Ti-C-N Coated Steel

Abstract

In this paper, we attempt to explain the decohesion mechanism of Ti-C-N films by an approximate numerical analysis of the elastic-plastic stresses to which the material is subject in rolling contact. Compressive and tensile stresses were observed forward and backward in the rolling contact. The results were used to predict trends in film decohesion with the elastic properties of films deposited by ion plating on tool steel substrates. It is important to analyze the stresses at the interface between films and substrates in determing the practical use of Ti-C-N-coated steels.
