采用球-平面接触微动磨损试验机考 察了轧制固溶316L不锈钢在不同极化状态下的微动磨蚀行为.结果表明:在阳极极化状态下 ,随着极化电位的升高,腐蚀疲劳微断裂作用增强,促进了微动损伤过程的发展;在阴极保 护状态下,摩擦系数随微动过程的变化规律及微动损伤形貌与阳极极化态下的存在显著差异 ,在阴极极化态下,微动摩擦副之间的粘着导致较高的微动摩擦应力状态,但与阳极极化态 相比并未产生严重损伤.
採用毬-平麵接觸微動磨損試驗機攷 察瞭軋製固溶316L不鏽鋼在不同極化狀態下的微動磨蝕行為.結果錶明:在暘極極化狀態下 ,隨著極化電位的升高,腐蝕疲勞微斷裂作用增彊,促進瞭微動損傷過程的髮展;在陰極保 護狀態下,摩抆繫數隨微動過程的變化規律及微動損傷形貌與暘極極化態下的存在顯著差異 ,在陰極極化態下,微動摩抆副之間的粘著導緻較高的微動摩抆應力狀態,但與暘極極化態 相比併未產生嚴重損傷.

The influence of applied potential on the frettin g corrosion-wear behavior of 316L stainless steel in saline solution has been i nvestigated with a test rig of ball-on-plane contact configuration. It has bee n found that under anodic polarization conditions, the friction coefficients and especially the steady-state fretting wear process is dependent on the anodic p olarization parameters. The higher the applied potential, the more severe the fr etting damage will be. This is because 316L stainless steel is of high chemical activity under anodic polarization, which promotes the fretting damage of the st eel. Contrary to the above, the fretting damage of 316L stainless steel is effec tively prevented by cathodic protection. This is because the adhesion between th e contact surfaces of the fretting pair can be abated by cathodic protection, th ough a relatively higher friction coefficient is recorded in this case.
