Title: Mechanical tests of gradient Ti/TiN/TiCN hard coating intended for tool production
Keywords: PVD, hard coatings, mechanical properties, mold making

Abstract: Nowadays, hard coatings are used practically everywhere in machine building and their variety is huge. During the operation of injection molds there are some problems with the rapid wear of the active elements, the ejection of the finished article, etc., which could be successfully solved by applying of a suitable coating. The main mechanical properties of gradient Ti/TiN/TiCN hard coating on Stavax ESR steel which was created by Physical Vapor Deposition (PVD) method, are investigated here. A special attention is paid to the wear resistance which was studied by the ball-on-flat method at different loads applied on the counter-part. The width of the carved traces was measured and using its value, the wear rate was geometrically evaluated. The obtained results are analyzed and recommendations for the practical use of the coating are given.
