Erosion and Abrasion Resistance, Mechanical Properties, and Structure of the TiN, Ti-Cr-Al-N and Cr-Al-Ti-N Coatings Deposited by CFUBMS

摘要

The results of structural studies and mechanical, abrasion, and erosion tests of single-layer and multi-layer TiN, Ti-Cr-Al-N, and Cr-Al-Ti-N coatings deposited on a closed-field unbalanced magnetron sputtering (CFUBMS) system using the ion-plasma technique are reported. It is demonstrated that, despite their low level of hardness (17-18 GPa versus 40 GPa for TiN), Ti-Cr-Al-N and Cr-Al-Ti-N coatings are superior to single-layer titanium nitride coatings in terms of their abrasive wear resistance and erosion resistance due to their structural features.
