Abstract
TiN coatings were deposited by Magnetron Sputter Ion Plating (MSIP) on the surface of high-speed steel W18Cr4V.The microstructure,coating thickness, micro-hardness and wear resistance of surface modification sample were investigated by the D/MAX-ⅢB X-ray diffraction tester, the coating thickness tester, the HV-1000 micro-sclerometer,the LKDM－2000 friction and wear tester,the S-3000N scaning electron microscopy.The influence of sputtering time,N2 partial pressures and sputtering current on the microstructure,coating thickness, micro-hardness and wear resistance of TiN coatings were also analysed.The best synthesis performance sputtering coatings of technologic scheme was established.
