Tribocorrosion denotes an irreversible material degradation for several metallic components used in corrosive environments, and it arises from the interplay between chemical, mechanical, and electrochemical processes. In this study, some investigation has been performed to compare the tribocorrosion behavior of AISI 1045 steel and AISI 2205 duplex stainless steel sliding against an alumina pin in seawater. The lowering in the open circuit potential (OCP) of AISI 2205 during the tribocorrosion demonstrates that its protective passive film was damaged by wear and resulted in a wear-accelerated corrosion in the wear track. However, sliding was found to accelerate the corrosion of the unworn areas for AISI 1045, leading to an anodic shift of the OCP. Moreover, the total material loss increased with an increase in the applied potential for both materials. It was revealed that AISI 1045 was more sensitive to corrosion under sliding than AISI 2205. Therefore, pure corrosion loss and corrosion-induced wear constituted the primary reasons for the degradation of AISI 1045 at applied anodic potentials.

摩擦腐蚀表示腐蚀环境中使用的几种金属部件发生不可逆的材料降解，它是由化学，机械和电化学过程之间的相互作用引起的。在这项研究中，已经进行了一些调查，以比较AISI 1045钢和AISI 2205双相不锈钢在海水中在氧化铝销钉上滑动时的摩擦腐蚀行为。摩擦腐蚀期间AISI 2205的开路电势（OCP）降低表明，其保护性钝化膜被磨损损坏，并导致磨损轨道上的磨损加速腐蚀。但是，发现滑动会加速AISI 1045的未磨损区域的腐蚀，从而导致OCP发生阳极移动。而且，随着两种材料的施加电势的增加，总材料损失也增加了。结果表明，AISI 1045比AISI 2205对滑动腐蚀更敏感。因此，纯腐蚀损失和腐蚀引起的磨损是AISI 1045在施加的阳极电势下降解的主要原因。
