摘　　要：进行了不同Al含量和Nb含量下Ti-Al-Nb系新型合金试样的抗高温氧化性能和耐高温磨损性能测试、比较和分析。结果表明:随Al含量和Nb含量的增加,试样的单位面积质量增重和高温磨损体积先减小后略有增大,抗高温氧化性能和耐高温磨损性能先提升后缓缓下降。14%Al含量下试样的单位面积质量增重和高温磨损体积分别较8%Al含量时减小了53.85%、50%;35%Nb含量下试样的单位面积质量增重和高温磨损体积分别较20%Nb含量时减小了43.75%、41.38%。Ti-Al-Nb系新型合金试样的Al含量优选14%、Nb含量优选35%。The high temperature oxidation resistance and high temperature wear resistance of Ti-Al-Nb alloy samples with different contents of Al and Nb elements were tested,compared and analyzed.The results show that with the increase of Al content and Nb content,the mass gain per unit area and high temperature wear volume of the sample decrease first and then increase slightly,and the high temperature oxidation resistance and high temperature wear resistance increase first and then decrease slowly.The mass gain per unit area and high temperature wear volume of the sample with 14% Al content respectively decrease by 53.85% and 50% comparing with those of the alloy with 8% Al content.And the mass gain per unit area and high temperature wear volume of the sample with 35% Nb content respectively decrease by 43.75% and 41.38% comparing with those of the alloy with 20% Nb content.The Al content and Nb content of Ti-Al-Nb alloy are optimized at 14% and 35%,respectively.
