中文摘要:
      为了提高冶金设备用铜质传热零部件的耐磨性和抗氧化性能,对纯铜进行了925℃深层渗铝12h +925℃固溶1.5h+300℃时效处理3h,研究了其金相组织特征及其耐磨性和抗热疲劳性能。试验结果表明:处理后试样表层组织主要由β’相组成,与纯铜试样相比,其磨粒磨损抗力和粘着磨损抗力分别是纯铜的2. 12倍和22. 59倍,9300C循环加热冷却250次后,其热疲劳质量损失率仅为纯铜的g%。
英文摘要:
      In order to improve the wear resistance and thermal fatigue resistance of metallurgical equipment copper heat transfer components, the pure copper samples were solid solution treated at 925℃ for l. 5 hours and aging heat treated at 300℃ for 3 hours after deeply aluminized at 925 ℃ for 12 hours. The microstructures and properties of the samples were studied. The results show that the microstructure of the solid solution and aging heat treated after deeply aluminized copper surface is β' , the abrasive wear resistance and adhesive wear resistance of solid solution and aging heat treated sample are the 2. 12 times and 22. 59 times of that of the pure copper sample respectively. The ratio of weightlessness of the thermal fatigue sample subjected to solid solution and aging heat treatment is 9 percents of that of pure copper sample after heated at 930℃ and cooled for 250 times.
