42CrMo钢/3.5%NaCl腐蚀疲劳门槛值的研究

A STUDY OF CORROSION FATIGUE THRESHOLD LIMIT OF 42CrMo STEEL/3.5%NaCl

本文针对石油开采工程中常用材料42CrMo钢的实际应用环境,就环境介质3.5％NaCl加入对42CrMo钢的“门槛值△K_(th)～复合比K_Ⅱ/K_Ⅰ曲线”的影响展开了研究,并就研究结果进行了分析讨论。

In this paper, the effect of the environmented medium (3.5% NaCl solution) on the relationship between the eorrosion fatigue threshold limit ΔKth of 42CrMo steel and mixed proportion KⅡ /KⅠ had been studied. The experimental results have been analysed and discussed.
