前言由于酸洗和电镀过程中,氢渗入到钢的内部,引起零件某些机械性能的恶化,这就是通常所称的氢脆现象。对于电镀氢脆这一潜伏性破坏因素,早已引起人们的重视,对此,曾有人作了许多试验与研究,并发表了不少文献。在国外,首先是美国的三大航空公司——洛克希德、波音和道格拉斯作了各种试验研究并制定了一系列有效对策。日本 Preface Due to pickling and electroplating, hydrogen penetrates into the interior of the steel and causes deterioration of some mechanical properties of the part. This is what is commonly referred to as hydrogen embrittlement. For the latent hydrogen embrittlement electroplating destructive factors, has drawn people’s attention, which, there have been many experiments and studies, and published a lot of literature. Abroad, the United States, the first of three major airlines - Lockheed, Boeing and Douglas conducted a variety of pilot studies and developed a series of effective countermeasures. Japan
