| 摘 要： | 用ＳＥＭ研究了浸在Ｈａｎｋ模拟体液中的轧态３１６Ｌ和铸态３１６Ｌ和铸态３１７Ｌ不锈钢在腐蚀疲劳期间产生的间晶腐蚀。结果表明，腐蚀疲劳初始裂纹是在腐蚀晶界上孕育产生的，在疲劳应力作用下，由沿晶扩展变为穿晶扩展；晶间腐蚀不是由碳化物析出造成晶界贫Ｃｒ产生的。而是一种非敏化晶间腐蚀。

| Abstract: | The behaviours of intergranular corrosion on the rolled 316L and cast 317L implant stainless steels were studied by using SEM in the process of corrosion fatigue in Hank physiological solution. It was concluded that the initial fatigue cracks engender at the corroded granular boundaries and propagate along intergranule first and then transgranule under the fatigue stress. The intergranular corrosion is not due to the chrome-deficiency induced by the precipitation of carbide at the granular boundary but due to non-sensitized intergranular corrosion. |
