摘 要: 研究了噴射成形Zn-27Al-1Cu合金棒坯的制備技術(shù)、熱擠壓工藝以及Zn-27Al-1Cu合金滑動(dòng)軸承的制備技術(shù)，分析了噴射成形Zn-27Al-1Cu合金的顯微組織、力學(xué)性能、耐磨性能。實(shí)驗(yàn)結(jié)果表明：采用噴射成形制備的Zn-27Al-1Cu合金的棒坯經(jīng)后續(xù)熱擠壓成形后，具有比傳統(tǒng)鑄造ZA27合金更高的力學(xué)性能和耐磨性能。這種由噴射成形Zn-27Al-1Cu合金制造的滑動(dòng)軸承在實(shí)際使用過程中，其壽命比傳統(tǒng)材料制造的滑動(dòng)軸承提高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.
