铸铁零件的等离子强化现代内燃机的功率大、转数高，所以它的零件也承受着日益增加的载荷。提高零件的耐磨性，特别是提高凸轮轮和摇臂的耐磨性早已成为正待解决的课题。目前，有两种解决方法，一是选择合适的材料，二是完善强化工艺。现在汽车和拖拉机凸轮轮采用的材料是... Plasma Enhanced Iron Castings Modern internal combustion engines have high power and high revolutions, so their parts are also subject to increasing loads. Improve the wear resistance of parts, in particular, to improve the wear resistance of the cam wheel and arm has long been a problem to be solved. At present, there are two solutions, one is to choose the right material, the second is to improve the strengthening process. Now the materials used in car and tractor cam wheels are ...
