摘　　要：为了防止钢铁材料表面在大气环境中发生氧化锈蚀,通常在钢铁零件表面镀锌或镀锌镍合金等防护层。但电镀过程可能会引起高强度材料的氢致开裂或氢脆延迟破坏,因此,探讨高强度材料电镀过程的氢脆敏感性至关重要。本文分析了电镀过程引起高强钢零件氢脆故障的案例和学者们的实验研究结果,探讨了电镀过程中氢的渗入过程,归纳了氢原子在零件内部的存在状态,对比了不同电镀溶液沉积过程中的氢脆敏感性,分析了镀层微观形貌对于氢原子逃逸和氢脆敏感性的影响,总结了热处理烘烤除氢工艺、材料氢脆敏感性评价方法等的研究现状。相关内容可为降低高强钢材料电镀氢脆敏感性的风险打下技术基础,更好的指导电镀高强度钢零件的应用。In order to prevent oxidative rust on the surface of steel materials in natural atmospheric environment,protective layers such as galvanized or galvanized nickel alloy are usually used on the surface of steel parts.Since the electroplating process may cause hydrogen embrittlement or hydrogen embrittlement delayed damage of high-strength materials,it is very important to investigate the hydrogen embrittlement sensitivity in electroplating of high-strength materials.In this paper,the hydrogen embrittlement failure cases of high-strength steel parts caused by electroplating process and the experimental research results of scholars were introduced,the infiltration of hydrogen during electroplating was discussed,the existence state of hydrogen atoms inside the parts was summarized,the hydrogen embrittlement sensitivity during deposition of different electroplating solutions was contrasted,the influence of coating microstructure on hydrogen atom escape and hydrogen embrittlement sensitivity were analyzed,the research status of hydrogen removal process by heat treatment and baking and evaluation methods of hydrogen embrittlement sensitivity of materials were summarized.The relevant content can lay a technical foundation for reducing the risk of electroplating hydrogen embrittlement sensitivity of high-strength steel materials,and better guide the application of electroplating high-strength steel parts.
