摘　　要：为提高Q235钢的耐磨性,采用固体粉末法对Q235钢进行Al-Si共渗处理.改变渗剂中Al粉质量分数,以研究Al对渗硅层耐磨性的影响.利用扫描电镜、维氏硬度计、磨粒磨损试验等手段对渗后试样的金相组织、硬度、耐磨性能进行表征.结果表明:Al粉质量分数为35%时,渗层厚度最大,渗层硬度最高,耐磨性能最佳.Siliconizing layer was prepared on Q235 steel by the solid powder method at 900℃ for 12h, using SiO2 as source, pure Al powder as reducer and a dual activator of NaF and NH4Cl. The microstructure hardness test and wear resistance test to analyze the effect of Al content on the wear-resisting performance siliconizing layer. The results show that the wear test and scanning electron microscope, when Al powder content is 35% permeability layer thickness is the maximum; permeability layer hardness is the biggest and wear resistance is the best.
