There are two ways for the abrasive particle movement relative to material's surface: sliding and rolling.
磨料颗粒相对于材料表面的运动方向上主要可分解为两种运动方式, 即 滑动和滚动.
Derived from the Newton law and Hertz equation, a dimensionless quantity, called the relative erosion strength, is found to be a constant during the impacting of an abrasive particle on ductile materials.
从牛顿定律和赫兹方程导出一个称为量钢一的量的相对冲蚀强度,发现在磨拉冲击韧度材料过程中保持不变。
The content ( by vo lume) of the former should be ≤ 0.88% for ≤ 16% cobalt alloy. Those over 0.88% in the standard photograph are pseudoimages resulting from too large particle slie of abrasive materials during polishing.
含钴量≤16%的合金中,共晶石墨的体积含量应≤c.88%,标准照片中>0.88%的照片,是抛光时研磨料粒子太粗造成的假象;
