抗磨添加剂与电弧喷涂耐磨涂层间的协同效应

Synergistic Effects of Anti-Wear Additive and Wear-Resistant Coating by Electric-Arc Spraying

研究了2种φ2 mm粉芯丝材电弧喷涂Fe-Cr-Ni涂层和7Crl3涂层以及与2种典型润滑油抗磨添加剂的协同效应,并借助X光电子能谱(XPS)研究了其协同作用机理.结果表明:DBP和ZDDP润滑油抗磨添加剂能明显地改善电弧喷涂Fe-Cr-Ni涂层和7Cr1 3涂层的抗磨性.添加剂DBP能显著地降低2种电弧喷涂涂层/GCr15摩擦副的摩擦系数,但ZDDP抗磨添加u剂的减摩效果不太显著.在含DBP和ZDDP添加剂油润滑条件下,涂层磨痕表面形成了摩擦化学反应膜.

In this paper, studied synergistic effects of Fe-Cr-Ni coating and 7Cr13 coating, which is made by electric-arc spraying f2mm powder core thread material, and anti-wear additive in two typical lubricating oil. The mechanism was studied with the help of X-ray electron spectrum (XPS). It was shown that anti-wear additive DBP and ZDDP can obviously improve anti-wear properties of electric-arc spraying Fe-Cr-Ni coating and 7Crl3 coating. DBP can greatly reduce friction coefficient of /GCr15 friction couple, but result of reducing friction of ZDDP is not obvious. After using additive DBP and ZDDP, friction chemical reaction film formed on the surface of coating.
