Tribological Behaviour of Nanostructured Ti-C:H Coatings Used for Biomedical Applications

Popis výsledku v původním jazyce

The tribological properties of Ti-C:H coatings were studied using pin-on-disc CSM Tribometer. The functional Ti-C:H layers were deposited by PECVD using magnetron sputtering of Ti-target in C2H2 + Ar atmosphere. The sets of coatings samples were preparedwith varying content of C:H components controlled by C2H2 flow. The typical thickness of Ti-C:H coatings varied from 2.5 to 3.5 um. The sliding tests were carried out at room temperature (RT) and at 100 °C using HS steel and ceramic Al2O3 balls with a diameter of 6 mm. The results showed relative clear correlation between tribological properties and coatings composition. There is assumed the commercial production for biomedical applications using Ti-C:H coatings deposited on Ti-alloy. The results acquired in this study will support the research and development of deposited surgical tools and prostheses with improved sliding properties.
