控制超高强度钢零件电镀渗氢,预防氢脆发生的方法

摘要

超高强度钢是一种综合性能优良的结构材料，氢脆敏感性高。零件的电镀过程极易发生渗氢，可导致氢脆延迟性断裂，引发事故。对电镀过程渗氢的主要环节(前处理、电镀过程及后处理等)进行分析、研究，总结出了控制渗氢，防止氢脆发生的实用、有效方法；对氢脆试验方法作了简要介绍。%Ultrahigh-strength steel is a kind of structural material of premium properties,and its sensitivity of hydrogen embrittlement is high.The electroplating process of the part is very easy to cause absorption hydrogen,and it may result in hydrogen embrittlement delay fracture in use with accident.By analyzing and researching main factor-preprocessing affected absorption hydrogen of electroplating process,electroplating process,and postplating etc,summarize a practical and valid method that controls absorption hydrogen of electroplating process to prevent hydrogen embrittlement.Make a brief intro-duction to test method for hydrogen embrittlement.
