TRIBOLOGICAL PROPERTIES OF TI/A-C:H NANOCOMPOSITE CARBON BASED COATINGS
Journal Title: Tribologia - Year 2016, Vol 267, Issue 3
Abstract
The paper presents the results of mechanical and tribological tests of Ti/a-C:H nanocomposite carbon coatings and a-C:H hydrogenated carbon coating. All coatings were deposited by magnetron sputtering technique at various acetylene gas flows in a vacuum chamber, resulting in different coatings properties. The conducted study determines hardness, elasticity modulus, fracture resistance, and tribological properties – wear and friction coefficient of deposited coatings. The lowest wear and coefficient of friction were exhibited coatings deposited at higher acetylene flows, 15-20 sccm. However, they are brittle and the critical load in scratch testing is several times smaller than in a case of softer coatings deposited at lower acetylene flow up to 10 sccm.<br/><br/>
