| 中文摘要: |
| 为提高铜质件的耐热性和耐磨性，采用纯铜深层渗铝内氧化试验方法制备了Al2 03/Cu表面复合材料，研究了纯铜深层渗铝内氧化的金相组织特征及性能，结果表明：与纯铜试样相比，深层渗铝内氧化试样的抗磨粒磨损性能和抗粘着磨损性能分别为纯铜试样的1. 85倍和9.4倍，抗热疲劳性大幅度提高，经250次热循环后，内氧化试样质量损失率为纯铜试样的0.88%。这种特性使得纯铜深层渗铝内氧化Al2O3/Cu复合材料在高温服役条件下更适合用作冶金设备用传热铜材料。 |
| 英文摘要: |
| To improve the heat resistance and wear resistance of coppery elements, the Al203/Cu composite material was prepared by intemal oxidation of deeply aluminized pure copper matrix. The microstructures and properties of the composite material were studied. The results show that the grain-abrasion resistance and adhesive wear resistance is 1. 85 times and 9. 4 times that of copper respectively; the thermal fatigue resistance of the composite is higher than that of copper, the weightlessness of thermal fatigue sample is 0. 880/o of that of copper. The specialty makes the Al203/Cu composite material by internal oxidation of deeply aluminized pure copper matrix is more fine to be the diathermanous copper material of metallurgical equipment in the high temperature service condition than the ageing and solution alloy of aluminized deeply pure copper. |
