摘要
研究了合金铸铁凸轮轴氩弧重熔淬火后强化层的组织、耐磨性及磨损机理。试验结果表明 ,合金铸铁凸轮轴氩弧重熔硬化层具有较高的抗擦伤性能和疲劳磨损性能 ,优良的热稳定性和莱氏体枝晶显著细化是提高耐磨性的主要因素。
The microstructure,wear resisting and abrasive mechanism of argon arc remelting area of alloyed casting iron camshaft is studied.The result showed that the properties of wear resisting and fatigue resisting of the argon arc remelted harding area is high. The heat stability and fine ledeburite is the main reason for the increase of the wear resisting.
