摘要：
Information of the wear resistance proprieties of coatings is urgently required by suppliers and users to provide confidence in the performance of engineering coatings. The balcrattring test has been used to investigated the abrasive wear resistance of a series of thin (3.5-5.8 mu m) PVD coatings of CrNx (0.18 <= x <= 1) on identical a DIN 1.4301 steel substrates. Two different abrasives, SiC and diamond were used. The hardness of the films was found to be in the range of 8-40 GPa. The aim of this paper is to evaluate the abrasion resistance of hard coatings, and low abrasive wear resistance of these coatings are compared. The results obtained show an excellent correlation between coatings hardness and abrasive wear resistance. The results were compared to those of a chromium nitride reference coating. The results obtained show an excellent correlation between coating hardness and abrasion resistance.
