摘 要: 初步研究了高鋁鋅基合金的粉末冶金工藝及其材料的摩擦磨損性能。通過氣噴氣冷法制取合金粉末，用壓制后真空燒結的方法制備高鋁鋅基合金粉末冶金材料。實驗結果表明，高鋁鋅基合金的粉末冶金試樣在干摩擦和油潤滑條件下的磨損率及摩擦系數均小于同一合金的鑄造試樣，但其壓潰強度有待提高。在實驗的基礎上還探討了該材料的耐磨減摩機理。

Abstract:The powder metallurgy of high aluminium-zinc alloy and its tribological characteristics have been studied. The alloy powder was produced by gas atomization. P/M material samples were made by pressing and sequent vacuum sintering. The results show that the wear rate and friction coefficient of P/M material samples are lower than the cast alloy samples of the same composition, but their compressing strength needs to be improved. Based on the experimental results, the wear-resisting and anti-friction mechanism of the P/M materials have also been probed.
Key words: high aluminium zinc alloy powder metallurgy friction wear
