【摘要】 利用新型超硬材料α-C₃N₄的抗腐蚀、耐磨损的特性,将其沉积在制造人工关节的材料钛合金TC4的表面后,再浸没在仿照人体体液中,加上高负载进行磨损实验.通过线性极电阻测试表明:表面沉积了α-C₃N₄的TC₄试样,比起表面未沉积α-C₃N₄的TC4试样,显示出了很好的抗腐蚀性能,使TC4的使用寿命提高近30倍.更多还原

【Abstract】 The new super hard material α-C₃N₄ has the characteristics of resisting erosion and abrasion. Wedeposited it on the surface of the titanium alloy TC4, which is the material usually used to make the artificial arthrosis.Then we put them in the edificial bodily humour and added high load to do abrasion test. The linear polar electricresistance test show that the TC4 sample with α- C₃N₄ deposited on the surface has better anti-erosion ability and itslongevity is about 30 times as long as the TC4 sample without α- C₃N₄ deposited on the surface.更多还原
