With graphite particle content increasing from 5% to 20%, wear weight-loss and friction coefficient of the composites are obviously declined, greatly improving wear resistance of the composites.
随着石墨颗粒含量从5%增加到20%,镁合金基复合材料的耐磨性得到明显的改善,磨损质量损失与摩擦系数都降低到较低水平。
This surface has extreme hardness (60 RC. ), excellent wear and corrosion resistance, and low coefficient of friction.
这表面有极高的硬度(60局。),耐磨性和耐腐蚀性,低摩擦系数。
However, in some application conditions, low hardness, big friction coefficient and poor wear resistance confine its extensive application in engineering.
然而,在某些应用条件下,钛合金的硬度低,摩擦系数大,耐磨性差。
