Crevices of artificial joints can become occluded and are prone to severe corrosion. Different crevice width was controlled to reveal its effect to corrosion for two commonly used alloys (316L stainless steel and CoCrMo alloy). The results show that 316L stainless steel with the narrowest (0.05 mm) width corrodes more easily and more severely. There is no typical crevice corrosion for CoCrMo alloy, and the exterior of the crevice has different degrees of corrosion due to the mass transfer effect caused by the crevice with different widths. The corrosion rate reaches the lowest value when the width is 0.1 mm.

CoCrMo合金与不锈钢316L人工关节材料在生理盐水中的缝隙腐蚀行为
人工关节的缝隙可能会堵塞并容易受到严重腐蚀。控制不同的缝隙宽度以揭示其对两种常用合金（316L 不锈钢和 CoCrMo 合金）腐蚀的影响。结果表明，宽度最窄（0.05 mm）的316L不锈钢更容易腐蚀，腐蚀更严重。CoCrMo合金不存在典型的缝隙腐蚀，由于不同宽度的缝隙引起的传质效应，缝隙外部有不同程度的腐蚀。当宽度为 0.1 mm 时，腐蚀速率达到最低值。
