摘要

采用加速腐蚀(5%NaCl盐雾)试验和旋转弯曲疲劳试验

研究了0.52%～1.00%Ni对2000 MPa级中碳弹簧钢NHS(%:0.44～0.45C、1.95～2.08Si、0.68～0.70Mn、0.90～0.92Cr、0.14～0.15V)腐蚀疲劳性能的影响。结果表明

增加NHS钢中的M含量

腐蚀坑深度降低

在5%NaCl水溶液中钢的点蚀电位增加

从而导致腐蚀疲劳强度提高。与传统的60Si2CrVA弹簧钢相比

NHS弹簧钢呈现出良好的耐腐蚀疲劳性能。

Abstract

The effect of 0.52～1.00 Ni on corrosion fatigue properties of 2.000 MPa grade medium carbon spring steel NHS ( 0.44~0.45C

1.95~2.08Si

0.68~0.70Mn

0.90~0.92Cr

0. 14~0. 15V) has been studied by using accelerated corrosion(5% NaCl salt spray)test and rotating bending fatigue test. Results indicated that with increasing the Ni content in steel NHS

the depth of corrosion pits in steel decreased and the corrosion pitting potential of steel in 5% NaCl aqueous solution increased as a result to increase the corrosion fatigue strength and life of the steel. As compared with conventional spring steel 60Si2CrVA

the spring steel NHS presented better anti-corrosion fatigue properties.
