Microstructure and tribological study of TiAlCN and TiTaCN coatings

The low coefficients of friction and wear rates transition metal carbonitride make them excellent candidates for applications. Coatings based on titanium alloyed with Ta Al were deposited using reactive magnetron sputtering the surface VT1-0 steel AISI 304. effect alloying carbonitrides acetylene flow during deposition structure, composition, tribological properties coating was studied. TiAlCN TiTаCN coatings in various flows along stable argon nitrogen flows. Scanning electron microscopy, optical X-ray phase analysis, sliding test (ball-on-disk method) two media used to study resulting coatings. average coefficient under without lubrication varied range 0.13-0.85 0.0015-0.081. From point view rate, it is shown that most wear-resistant conditions TiAlCN-2. can be useful as protection machine parts or tools are subject wear.
