研究了17-7PH不锈钢在沿海大气环境下的接触腐蚀行为。结果表明,在秦皇岛和广东暴晒的17-7PH型不锈钢,无论装配与否,都没有出现显著的腐蚀。而且胶结装配方式不会降低材料的疲劳寿命。涂漆可有效防止17-7PH型不锈钢的电偶腐蚀及大气腐蚀。
The contact corrosion behavior of 17-7PH stainless steel in coastal atmosphere was studied. The results show that the 17-7PH stainless steel exposed in Qinhuangdao and Guangdong shows no significant corrosion whether assembled or not. And cementing assembly will not reduce the fatigue life of the material. Painting can effectively prevent Galvanic corrosion of 17-7PH stainless steel and atmospheric corrosion.
