The seizure resistance of balls and the scoring resistance of gears, which are sulphurized at a temperature of about 463 K were investigated by a four-ball machine and a power-circulating gear machine, respectively. As a result, it was clarified that the seizure resistance of the sulphurized balls and the scoring resistance of the suplhurized gears were about 1.5-2.0 times larger than those of the unsuplhurized ones, and a considerable relationship between the siezure resistance in the ball tests and the scoring resistance in the gear tests was recogized. Further, the scoring resistance of the gears was increased with increasing viscosity of the lubricants.To clarify the seiezure resistance and the frictional characteristics of stainless steel ball, which was thermally diffused after Sn-plated, four-ball test was run under dip-feed lubrication and dry friction. From the seizuring test, the following results were obtained. Under dip-feed lubrication, the coefficient of friction was decreased with increasing thickness of the Sn-diffused layer, and the seizure resistance of the ball was increased with increasing thickness of the diffused layer. The seizure resistance of the ball in which the diffused layer was 8 m thick was about 2.6 times larger than that without diffused layer. Further, under dry friction, the running time at the incipient stage of seizuring with the balls in which the thickness of the Sn-diffused layer exceeded 4 m was about 5 min independently of the thickness of its layer, and it was considerably longer than that without diffused layer.

采用四球机和动力循环齿轮机分别研究了在463 K左右的温度下硫化的钢球和齿轮的抗卡扣性和抗刻痕性。结果表明，含硫钢球的抗压阻力和含硫齿轮的抗压阻力约为未含硫钢球的1.5 ~ 2.0倍，钢球试验中的抗压阻力和齿轮试验中的抗压阻力之间存在相当大的关系。此外，齿轮的划痕阻力随着润滑油粘度的增加而增加。为明确镀锡后热扩散的不锈钢球的抗抓抓性和摩擦特性，在浸渍润滑和干摩擦条件下进行了四球试验。从癫痫发作试验中，得到以下结果：蘸料润滑时，摩擦系数随扩散层厚度的增加而减小，球的抗卡扣性随扩散层厚度的增加而增大。有扩散层厚度为8 m的球的抗癫痫能力比没有扩散层的球大2.6倍。此外，在干摩擦条件下，sn扩散层厚度超过4 m的球在抓球初期的运行时间与sn扩散层厚度无关，约为5 min，且明显长于未扩散层的球。
