【摘要】 以高温硬度作为高温强度和耐磨性的参考评价指标，试验研究了铝、铜、硅、锰等的含量对高铝锌合金高温硬度的影响，并由此而研究出Ｚｎ－Ａｌ４３，型高铝锌合金的耐磨性优于高强度锌合金ＺＡ２７和挤压加工铝青铜ＱＡｌ１０－３－１．５，故有可能进一步扩大高铝锌合金的应用范围。更多还原

【Abstract】 Hardness at elevated temperature was chosen as a reference indication ofelevated temperature strength and wear resistance,and effects on the elevated temperature hardness of contents of aluminium,copper,silicon and manganese were experimentally studied. This has led to develop a Zn-A143-type alloy, presenting better wear re-sistance than the high strength zine alloy-ZA27 and a squeezed copper alloy QAI 10-3-1.5.This implies that the application of high aluminium zine alloys might be further extended.更多还原
