摘要: 用新组建的微尺寸试样腐蚀疲劳实验平台研究了304不锈钢微试样在腐蚀性介质(0.9% NaCl溶液)和实验室空气中的疲劳性能?结果表明:预腐蚀后,微试样表面腐蚀形貌为均匀腐蚀,没有发现明显的点蚀特征?微试样在空气中的疲劳寿命为107次,是腐蚀介质中疲劳寿命的10~100倍? 腐蚀疲劳过程中伴随着最大载荷的降低,且在疲劳断裂前很短的时间内,最大载荷急剧降低?腐蚀疲劳断口上没有明显的腐蚀疲劳长裂纹出现?

Abstract：Fatigue tests were performed using a special developed testing machine for 304 stainless steel micro-sized specimens in both the laboratory air and the aggressive (0.9% NaCl solution) environments. The experimental results showed that corrosion behavior on the surface of micro-sized specimens was mainly general corrosion and no obvious corrosion pits were found after pre-corrosion. Corrosion fatigue life of micro-sized specimen in air is about 107 cycles, which is about 10~100 times larger than that of the micro-sized specimen in corrosive solution. The decreasing value of maximum load was monitored during the course of corrosion fatigue tests and rapid decreasing value was observed at the terminal stage of corrosion fatigue tests. A detailed fractographical analysis was presented and no long corrosion fatigue crack was found on the fracture surface.

Key words： MEMS corrosion fatigue austenitic stainless steel maximum bending stress
