氮离子注入对钻杆接头材料表面硬度的影响

Effect of Surface Hardness with Nitrogen Ion Doping for Drill Rod Joint Material

摘要:

对钻杆接头材料30CrMnSiA钢的样品进行氮离子注入表面改性试验，结果表明，在不同载荷的情况下，选用氮的注入量为50×1017 N+/cm2是比较合适的，氮离子注入后样品的表面努氏硬度提高1倍多。

Abstract:

The surface property modification experiment was carried out with nitrogen ion doping in 30CrMnSiA steel materials. The experimental results show that the proper doping dose is 50×1017 N+/cm2 in various load. The Knoop surface hardness of 30CrMnSiA steel is more than one time higher than treating before.
