Characteristics of Surface Layer of Chromium Cobalt Alloy Coated with Titanium Nitride and Zirconium Nitride

Overview

Technically pure titanium or its alloys are broadly used in recent oral implantology. The material has optimal biological characteristics but its technological processing is difficult. The aim of our research was to improve the technological processing of a cromium cobalt alloy and to maintain the biological characteristics of the material. We focused on a cromium cobalt alloy coated with biomaterials titanium nitride and zirconium nitride. Our study brings a report from the evaluation of mechanical and physical characteristics of the coated surface of the cromium cobalt alloy. The obtained results are promising for oral implantology. The study is a part of the project No. 7356-3 of the Internal Grant Agency of the Ministry of Health of the Czech Republic.

Key words:
