一、前言在腐蚀介质中,金属同时承受腐蚀和交变应力作用时,疲劳强度叫显降低,这就是所谓的腐蚀疲劳。虽然,腐蚀疲劳明确是指在清水、盐水和酸性溶液中等而言,但是在大气中的影响也不可忽视。而且,在这种情况下腐蚀疲劳进一步可分为由于吸附大气中的氧、水蒸汽、其他气体及油脂等而产生吸附疲劳和由于电化学机理而产生湿气腐蚀的腐蚀疲劳。 First, the preface In the corrosive medium, the metal at the same time withstand the role of corrosion and alternating stress, the fatigue was significantly reduced, which is the so-called corrosion fatigue. Although, corrosion fatigue is clearly defined as clear water, salt water and acidic solution, but in the atmosphere can not be ignored. Further, corrosion fatigue in this case can be further classified into corrosion fatigue caused by adsorption of oxygen, water vapor, other gases, grease and the like in the atmosphere and moisture corrosion due to electrochemical mechanism.
