Tribological Properties of PVD CrAlN Coating Tools

Article Preview

Abstract:

The paper reports the tribological properties of the CrAlN coating tools at different speeds and loads. The coating was deposited on 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 sallower as speeds increased and the coating presented adhesion phenomenon under low load. CrAlN coating showed excellent anti-wear properties at high speed and low load, and was more suitable for these similar working conditions.
