对经不同预先热处理钢的渗硫层的机械性能以及结构特点、化学成分进行了观察测定，提出了硬度沿层深的变化规律．并以销盘摩擦方式用标准微型钢球与渗硫处理的钢制圆盘进行摩擦特性试验．
The mechanical properties, structural characteristics and chemical composition of the sulphided layer through different pre-heat-treated steels were observed and measured, and the variation of hardness along the layer depth was proposed. The friction characteristics of the steel disc with standard micro-steel ball and sulfur-infiltrated steel were tested by means of pin-plate friction.
