摘要
本文通过应用实践考核,并对40CrNiMoA 和2Cr18Ni8W2A 钢经离子氮碳共渗处理前后的氢量测定,证明在离子氮碳共渗处理后,氢脆迹象不仅没有出现,且最终是使原材料中的含氢量减少.
The practical observation and actual measurement of the hydrogen content before and after the lonitrocarburizing of steels 40CrNiMoA and 2Cr18Ni8W2A show that hydrogen brit-tleness does not occur after ionitrocarburization,and moreover,hydrogen content is finally reduced.
