采用球－平面接触微动设备，对３１６Ｌ不锈钢在不同ＮａＣｌ溶液中微动过程力学化学交互作用进行了研究，并解析了材料微动损伤速率与溶液腐蚀特性之间的关系。结果表明，材料微动过程力学化学作用相互促进，力学损伤在微动损伤过程中占居主导作用。强碱性、强酸性及溶液富含Ｃｌ＾－的情况下，都可导致材料严重微动损伤，而在中性条件下，力学因素对化学损伤促进作用最为明显。
The synergistic effect between fretting warand cornion of 316L stainless steel (316LSS) in different NaCl solutions has been investigated with a sphere-plane contact device. ?he results shaved that the synergistic effect was remarkable, while mechanical action was the daninative factor for inducing damage. ?he evolutions of mechanical damage rate (including corrosion mted section) and synergistic damage against the variations of pH and concentration of U-of the solutions wen? similar to each other. On the other hand, the evolution of fretting current as a function of time was of inter relationship with the occurrence of local armion such as crevice attack in fretting. Both heavy alkaline, acidic medim and the solution of U-concentration in it d d result in serious fretting damage. And mechanical action might be of rn ranarkable pmn,tion to corrosion in neutral mediums.
