| Abstract: |
| 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. |
