通过表面机械研磨处理（SMAT）在纯钛表面制备了厚度为30 μm的纳米晶（NC）层。显微组织观察表明，晶粒尺寸随着深度的增加而增大。SMAT试样与粗晶试样相比，摩擦系数降低，耐磨性提高。SMAT试样硬度的提高是其耐磨性提高的主要原因。
A nanocrystalline (NC) layer with the thickness of 30 µm was produced on pure titanium surface by surface mechanical attrition treatment (SMAT). Microstructure observation indicated that the grain size increases with depth from the treated surface. The friction coefficient decreases and the wear resistance increases with the SMAT sample as compared to its coarse-grained counterpart. The improvement of the wear properties could be attributed to the higher hardness of SMAT sample.
