热处理对Ni-P基镀层耐高温腐蚀磨损性的影响

Effects of Heat Treatment on Corrosion and Wear Resistance of Ni-P-base Chemical Plating Coating at High Temperature

Ni P化学镀层经过热处理后 ,镀层硬度、耐蚀性、耐磨性得到提高。在Ni P化学镀的基础上 ,加入元素Co和SiC微粒 ,形成Ni Co P SiC复合镀层 ,经过 10 0～ 6 0 0℃回火后 ,与Ni P镀层相比 ,复合镀层表现出高硬度、高温耐磨性变化趋势小的特点 ,尤其经过 30 0℃回火后 。

After heat treatment, Ni P plating coating has good hardness,crossion and wear resistances.Then, by adding some particles such as Co and SiC, the Ni Co P/SiC composite plating coating can be formed, and this coating, through 100～600℃ tempering,has more better hardness, crossion and wear resistances,especially at 300℃ tempering, in comparison with the Ni P coating.
