Ni-P/CaF_2复合镀层的高温抗氧化及耐磨性能

The Anti-oxidation and Abrasion Performance in High Temperature of Ni-P/CaF_2 Composite Coating

基于化学镀 Ni- P镀层的耐腐蚀和 Ca F2 粒子的高温自润滑性能 ,设计并获得了化学镀 Ni- P/Ca F2 复合镀层 ,通过自行设计制造了用于高温耐磨性能测试的试验机。研究表明 ,该镀层在高温条件下具有优异的抗氧化性能和自润滑减磨性能。而且在 70 0℃以下 ,随测试温度的增加 。

The electroless Ni P/CaF 2 coating, which combines the anti oxidation performance of electroless Ni P coating with the self greasy property of CaF 2 in high temperature was designed A testing machine was also designed to measure its abrasion performance in high temperature It is shown that Ni P/CaF 2 has good performance Moreover, the abraded quantity of coating is decreased with the increasing of testing temperature under 700℃
