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 0×1017N+/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。
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 50×10^(17) N^+/cm^2 in various load. The Knoop surface hardness of 30CrMnSiA steel is more than one time higher than treating before.
