摘要
研究了铸态ZA合金的微观组织和耐磨性。结果表明:高铝锌合金的铸态组织由初生α相和(α+η)共析体组成。随着铝含量的增多,合金中的初生α相增多,共析体减少,合金的二次枝晶臂间距变化不明显;同时合金的耐磨性随铝含量的增多而增大。
The microstruαure and wear resistance of as cast ZA alloy was investigated. The results show that the microstruαure of high aluminum Zn-based cast alloy consists of primary phase α and （α＋η） euteαoid. The quantity of primary phase α increases and the euteαoid （α＋-q） decreases with the increase of aluminum contents in the alloy, while the secondary dendrite arm spacing of the alloy has no remarkable change. The wear resistance of the alloy increases with the increase of the aluminum contents.
