Wear and corrosion involve mechanical and electrochemical mechanisms, and the combined action of these mechanisms often result in significant mutual reinforcement.

腐蚀磨损是同时涉及力学因素和电化学因素的复杂的材料的流失过程，通常条件下，腐蚀磨损不是纯磨损和纯腐蚀的简单叠加，还有两者间的协同作用，为定量描述腐蚀与磨损的促进程度、进一步完善腐蚀磨损机理，本文利用腐蚀磨损协同作用率值的大小来分析腐蚀和磨损的交互作用程度，结果表明：本文制备的镀层，在5％H_2SO_4溶液中腐蚀磨损时，机械磨损是造成镀层表面材料流失的主要原因，腐蚀和磨损的协同作用为次要因素。

When the parameter matching of the wheel location is improper, namely, the matching between the wheel toe-in and the wheel camber angle is ill-suited, abrasion of the two wheels of the same steering axle is inside or outside simultaneously, because of wheels sideslip. However, when double-front-axle steering system failure take place, abrasion of the two wheels of the same steering axle is in the same side, and that, tyre abrasion direction of front and back steering axles is rightabout. That is to say, if tyre abrasion of front steering axle lie in the left side, tyre abrasion of back steering axle lie in the right side to a certainty, which is the rule of tyre abrasion of double-front-axle steering automobile.

当定位参数匹配不当时，同一转向轴上左右车轮的磨损部位都在内侧或外侧，原因是左右车轮在滚动的同时还要产生相向或反向侧滑；而双前轴转向汽车前、后转向轴引导汽车转向方向不一致时，同一转向轴左、右车轮的磨损部位都在同一侧，而且前、后转向轴上的车轮偏磨损方向正好相反，即如果前转向轴左、右车轮磨损部位在左侧或右侧，那么后转向轴左、右车轮磨损部位就在右侧或左侧，这是双前轴转向汽车特有的轮胎磨损规律。
