Abstract:X32CrMoV33 hot work tool steel samples coated with AlTiN and AlTiON were submitted to thermal cycling under conditions that approximate thixoforming of steels and to sliding wear tests at 750... and residual compressive stresses inherited from the deposition process. The impact of AlTiN and AlTiON coatings on the high temperature wear resistance, on the other hand, is favourable......
of specimens as compared with that of unreinforced specimen. The friction coefficients of specimens decrease with increasing of testing temperature. The wear rates of Fe-Cr-B alloys decrease firstly... of specimens were polished by abrasive paper. The wear test was conducted under the load of 10 N and sliding speed of 0.20 m/s. Meanwhile, the turning radius is 5 mm with a testing time 30 min......

. The thicker Cr interlayers result in reduced critical load values. Moreover, the wear resistance of the Cr-Al-Si-N coatings is greatly enhanced by introducing the Cr interlayer with thickness of 60 nm in spite of the decreased microhardness. The friction coefficient of the coating system is also moderately reduced. Key words: Cr-Al-Si-N coating; Cr interlayer; hardness; adhesion; wear 1......
