| 摘 要： | 采用双级雾化水冷快凝与粉末冶金技术制备了（2024Al)-20Si-5Fe(质量分数.%)耐磨合金。分析了合金的微观组织。利用磨损实验研究了合金的耐磨性和磨损失效形式。结果表明：快凝粉末冶金合金具有比铸造合金更细小的微观组织。更高的耐磨性和减磨性。耐磨性是铸造合金的2．5－4倍。快凝合金的磨损失效形式主要是磨粒磨损和疲劳磨损。耐铸造合金的磨损失效形式主要是磨粒磨损、粘着磨损和部分氧化磨损。

| Abstract: | A rapidly solidified (2024Al)-20Si-5Fe powder alloy has been prepared by two-stage atomization with water-cooling. The microstructure characteristics and wear behaviors have been investigated with electron microanalysis and wear test. The principal test results show that the rapidly solidified alloy has finer microstructure and higher wear resistance, as well as good anti-attrition than those of the cast alloys with the similar composition. The main wear-out-failure ways of the rapidly solidified alloy are grain-abrasion and fatigue wear, but for the cast alloy the main ways are grain-abrasion, sticking wear and oxidizing wear. |
