摘要 采用多弧离子镀设备,在高速钢W18Cr4V上先进行等离子氮化,再沉积TiN薄膜,研究了不同渗氮温度和时间对PN+TiN薄膜组织和性能的影响。结果表明,温度为500℃左右和时间为2h以上条件下对W18Cr4V进行渗氮处理后再沉积TiN薄膜,可以得到最佳的薄膜表面显微硬度(1800~2000HV0.05)和膜/基结合力(50N),涂层耐磨性也得到明显提高。 TiN thin films were deposited after plasma nitriding by multi-arc ion plating system on high speed steel W18Cr4V. The effect of different nitriding temperatures and times on the preparation and properties of PN + TiN films were studied. The results show that the optimal surface microhardness (1 800-2 000 HV005) and adhesion strength (50 N) can be gained when the film is deposited after plasma nitriding at 500 ℃ for over two hours, and the wear resistance of the coating is enhanced remarkably.
