【摘要】 硫在钢中形成的硫化物种类有很多,其在大部分钢中还是作为有害元素存在。但是,在有些钢种中硫也能作为有益元素而改善钢的性能。例如:易切削钢中的MnS割断了基体的连续性而使车屑易断,改善了钢材的切削性能。低碳钢中纳米尺寸弥散硫化物粒子可以钉扎晶界,阻碍其运动导致晶粒细化。FeS、MoS₂、WS₂都具有优良的润滑性能,在涂层、固体润滑剂等方面都有很好的润滑效果。高硫钢中含有大量的硫化物,具有良好的自润滑、减摩、耐磨、耐热性能。更多还原

【Abstract】 Various sulfides can be founded in steels,which were regarded as harmful to the properties of the steels.But in some sulfides were useful to improve some properties such as machinability and antifriction.The nanometer sized sulfides precipitated from low carbon steel can pinning the grain boundary and block recrystallization,leading a fine grain structure. FeS、MoS₂、WS₂ all possess excellent lubricating properties and alloy containing this kind of sulfides had self-lubricity, antifriction,abrasion resistance and heat resistance.更多还原
