一、高强度钢的防护与 镉—钛电镀 随着航空工业的发展,高强度钢的使用日趋广泛。但是,高强度钢的防护,一个众所周知的难题就是氢脆,即材料受氢的影响,在低于其屈服强度的应力条件下,容易发生早期脆性断裂。而且,材料强度越高,受氢程度越严重,所受应力越大,氢脆危险性也越大。电镀及表面处理作业中的酸洗、腐蚀、阴极除油、电镀等 First, the protection of high-strength steel and cadmium - Titanium plating With the development of the aviation industry, the use of high-strength steel is increasingly widespread. However, one of the well-known problems of high-strength steel protection is hydrogen embrittlement, that is, the material is affected by hydrogen. Early brittle fracture tends to occur under stress conditions below its yield strength. Moreover, the higher the material strength, the more severe the degree of hydrogen, the greater the stress, the greater the risk of hydrogen embrittlement. Electroplating and surface treatment operations pickling, corrosion, cathode degreasing, plating and so on
