摘　　要：研究了不同过渡层TiN涂层结合力的影响 ,用划痕法测定了临界载荷Lc,用扫描电镜观察了划痕形貌。结果表明 ,4种TiN复合涂层的结合力和硬度均明显高于TiN单层 ,其中Ni W过渡层对结合力提高幅度最大 ,并对TiN涂层起到有力的支撑作用。以M2为基体的TiN复合涂层的临界载荷均高于硬度较低的、以Effect of different interlayers on adhesion strength of TiN coating was investigated. The critical load Lc of TiN coating was measured by means of scratch test.The scratch morphology was observed by SEM. The results showed that four kinds of TiN composite coatings possess higher adhesion strength and microhardness than single TiN coating.Among the four kinds of TiN composite coatings Ni W+TiN composite coating possesses best adhesion strength. Interlayer provides a stronger support for top TiN layer. Critical load of TiN coating on M2 substrate is better than that of TiN coating on 3Cr2W8V substrate with lower hardness.
