选择铝锰共晶合金及其复合材料作为研究对象,用XRD,SEM,EDS分析试样.首先分析了试样的金相组织,再分析了它们在三种摩擦条件下的磨损失重、摩擦因数及磨痕形貌,最后分析其耐冲蚀性能.结果表明:Al2O3颗粒的加入改变了铝锰化合物的形态；试样在仅有腐蚀液条件下的磨损量和摩擦因数最大,在有腐蚀液加磨粒条件下次之,在干摩擦条件下最小；从磨痕形貌可知在仅有腐蚀液条件比在腐蚀液磨粒条件有更多的凹坑,在腐蚀液磨粒条件比干摩擦条件有更深的犁沟.在7m/s冲蚀速度下,冲蚀试样的磨损率随磨粒粒径的增大呈先增大后减小的趋势；在3.5m/s下,磨损率随磨粒粒径的增大而逐渐减小,合金在0.15～0.212mm粒径下实验后出现“增重”现象.
