中文摘要：对泵车耐磨件进行自纳米化处理；用金相、扫描电镜、X射线衍射和表面显微硬度测试仪对纳米化处理的表面进行观察分析，发现材料表面获得纳米层，为后续渗碳、渗氮及热处理工艺提供组织准备。
英文摘要：The self-nanocrystallization treatment of wear-resistance subassembly was carried out. The treated material surface was observed and analyzed through metallography microscope, SEM, X-ray diffraction and micro-hardness tester. The results show that the nanolayer formed in the material surface can provide a microstructure preparation for carboning, nitriding and other heat treatments.
