选用压铸铝硅合金、铁基粉末冶金、灰口铸铁进行摩擦对比试验。结果表明 ,在给定的滑动摩擦条件下压铸铝硅合金的耐磨性最高 ,加工硬化能力最强 ;铁基粉末冶金仅次于压铸铝硅合金 ;灰口铸铁的耐磨性及加工硬化能力最差。
Selection of die-casting aluminum-silicon alloy, iron-based powder metallurgy, gray cast iron friction contrast test. The results show that the die-cast aluminum-silicon alloy has the highest wear resistance and the highest work-hardening ability under a given sliding friction condition. Iron-based powder metallurgy is second only to the die-cast aluminum-silicon alloy. The wear resistance and work-hardening ability of gray cast iron Worst.
