摘要

对过共晶铝合金颗粒增强复合材料在不同的工艺条件下（即不同的浇注温度、模具温度和离心机转速）成形的5个铸件在铸态、T4态和T6态的金相组织、耐磨性和硬度进行对比分析

以得到最适合做制动盘的材料和成形工艺。研究结果表明

Al-21Si-5Mg-1Cu-1Ni-0.2Ti-0.4Mn材料在浇注温度为757℃、模具温度为100℃和离心机转速为400r/min条件下浇注

并进行T6处理后

可得到硬度（HRB）为89.6和耐磨性较好的材料

可用于制作制动盘。

Abstract

The microstructure

wear resistance and hardness of the five brake discs which were produced by three kinds of composites at different processing conditions

such as different pouring temperatures

mould temperatures and rotating velocities of centrifugal machine

were comparatively analyzed in as-cast

T4 and T6 treatment composite in order to provide the most suitable materials and forming process for brake disc.The results indicate that Al-21Si-5Mg-1Cu-1Ni-0.2Ti-0.4Mn alloy which is poured at 757℃ into permanent mold with 100 ℃ and 400 r/min exhibits a better wear resistance and hardness of HRB89.6

showing a desirable material for brake disc.
