采用Taber磨料磨损试验定量研究了晶粒细化对纯镍耐磨性的影响。随着晶粒尺寸从多晶减小到纳米晶范围，耐磨性如从增加的硬度预期的那样显著增加，并且由于磨损的体积损失遵循Archard定律。在泰伯磨损试验后，在多晶镍上观察到广泛的塑性变形。随着晶粒尺寸的减小，
The effect of grain size reduction on the wear resistance of pure nickel was investigated quantitatively using the Taber abrasive wear test. As the grain size decreases from the polycrystalline to nanocrystalline range, the abrasive wear resistance increases considerably as expected from the increased hardness, and the volume loss due to wear follows Archard’s law. Extensive plastic deformation is observed on the polycrystalline nickel after the Taber wear test. With decreasing grain size,
