| 摘 要： | 在前期研究工作的基础上,着重讨论了不同颗粒体积分数对Al2O3/钢基复合材料900 ℃下高温磨料磨损抗力的影响。结果表明:适当的颗粒体积分数(39 %左右)的复合材料因颗粒对基体保护好,起主要抗磨作用,因而高温抗磨性较好;较高或较低颗粒体积分数的复合材料因颗粒脱落或基体磨损严重使得其高温抗磨性较低。

| Abstract: | Based on previous work, abrasive wear resistance of Al2O3/steel composites with different Al2O3 particle volume fraction (VOF) at 900 ℃ was investigated. It can be got from the experimental results that a suitable particle volume fraction is important to protect the metal matrix from wear at elevated temperature. The less the particle VOF, the poorer the abrasive wear of the composites due to bulk matrix easily worn off by grits. The more the particle VOF, however, the poorer the abrasive wear of the composites, too. The reason is that Al2O3 particles are easily dug out by grits during wearing. When the particle VOF is 39 %, the wear resistance of test composites is excellent. |
