摘要： 通过改变等离子弧淬火条纹与运动方向的夹角,在不同载荷、不同速度条件下测试其在往复运动条件下的摩擦因数·研究表明,等离子弧淬火可以改变局部金相结构,提高硬度,大幅度改善其摩擦学性能;改变等离子弧淬火条纹与运动方向的夹角,可以改变摩擦副的摩擦因数,并且当等离子弧淬火条纹与运动方向夹角成90°～78°时,润滑条件最好,因此摩擦因数最小,减摩性能最好;在相同速度下,随着载荷的增加等离子弧淬火条纹摩擦因数减小;摩擦表面的等离子弧淬火条纹的方向设计将成为提高材料寿命、减少能源消耗的一种简单可行的方法·

Abstract: By changing the angle included between plasma-arc quenched stripe and moving direction, the friction factor in reciprocating motion was investigated at/under different speeds/loadings. The results indicate that the plasma-arc quenching process can change partly the metallographic structure of a workpiece, increase its hardness and greatly improve its frictional nature and function. Furthermore, changing the angle included between plasma-arc quenched stripe and moving direction can change the friction factor of related surfaces. When the angle is in the range from 90° to 78°, the lubrication conditions are optimized, so that the friction factor is the smallest with the best antifriction performance. In addition, the friction factor of plasma-arc quenched stripe can be reduced with the increase of load when keeping the speed constant. A conclusion is thus drawn that how to design the direction of plasma-arc quenched stripe on frictional surface is important because it is available to prolong the service life of the parts/materials to be used and reduce energy consumption.
