【摘要】 目的研究钴-铬合金表面氮化钛薄膜的制备及其机械性能。方法应用多弧离子镀技术制备氮化钛薄膜,在金相显微镜下观察薄膜形貌,并通过划痕法和磨损实验测试膜-基结合强度及薄膜的耐磨性。结果钴-铬合金试样表面形成一层致密、均匀、平滑的金黄色薄膜,X射线衍射证实薄膜成分为氮化钛,膜-基结合力平均值为77N,同等磨损实验条件下,镀膜试样的失重量仅为未镀膜者的1/5。结论用多弧离子镀技术可以在牙科钴-铬合金表面制备机械性能良好的氮化钛薄膜。更多还原

【Abstract】 Objective To evaluate the preparation and mechanical function of TiN coating on Co-Cr alloy.Methods Multi-arc ion plating was used to prepare TiN coatings.Microstructure,bonding force and the wear resistance were measured by metallurgical microscope,scratch method and wear test,respectively.Results It is found that pure TiN films appear on the Co-Cr substrate.The average value of bonding force is 77 N.In the same experimental condition,the weight loss of coated samples is only 20 percent of that of uncoated ones.Conclusion TiN film with satisfactory mechanical properties can be prepared by multi-arc ion plating.更多还原
