Friction and Wear Behaviors of CAPVD TiAlN Coating

Abstract:

The paper reports friction and wear study of TiAlN coating at different speeds and loads. The coating was deposited on YG6 (WC+6 wt.% Co) cemented carbide by cathodic arc physical vapour deposition technique. Ball-on-disc wear tests were performed on the CETR UMT-2 test system against SiC balls. The coating character and test results were obtained through SEM, XRD and Wyko surface profilometer. The results are as follows: The value of friction of coefficients decreased and depth of wear tracks became smaller as speeds and loads increased. TiAlN coating showed excellent anti-wear properties at high speed and high load, and was more suitable for these similar working conditions.
