摘 要: 研究了喷射成形Zn-27Al-1Cu合金棒坯的制备技术、热挤压工艺以及Zn-27Al-1Cu合金滑动轴承的制备技术,分析了喷射成形Zn-27Al-1Cu合金的显微组织、力学性能、耐磨性能。实验结果表明:采用喷射成形制备的Zn-27Al-1Cu合金的棒坯经后续热挤压成形后,具有比传统铸造ZA27合金更高的力学性能和耐磨性能。这种由喷射成形Zn-27Al-1Cu合金制造的滑动轴承在实际使用过程中,其寿命比传统材料制造的滑动轴承提高150%以上。

Abstract:Producing process of spray formed Zn-27Al-1Cu billets, hot extrusion process and producing process of sliding bearing were studied. The microstructure, properties and wearability of spray formed Zn-27Al-1Cu billets were also studied. The results of experiments and application show that the strength of hot extruded Zn-27Al-1Cu from spray forming process is much better than those of Babbit and cast ZA27 alloy. The durability of new type sliding bearing is 150% more than that of conventional one.
