wear intensity

To attain good strengthening effect with good thermal intensity and wear-resisting property, it is very important to determine optimized heat treatment process parameters.

为了使热处理后的ADC12合金保持较好的强化效果，同时又具有较好的热强度和耐磨性，确定优化的热处理工艺参数显得尤为重要。

In virtue of abraser and vibrating sample magnetometer, the effect of rare earth element cerium on wear volume, magnetic intensity, coercitive force and magnetic permeability of electroless Co-Ni-B alloy coating are studied.

借助磨损试验机和振动样品磁强计等研究了稀土金属Ce对化学镀Co-Ni-B合金镀层磨损体积、磁化强度、矫顽力和磁导率的影响。

When the brake speed is 3000 r/ min, the material's wear intensity is minor.

制动速度大于4000r/min时，摩擦系数迅速下降；
