【摘要】 石墨铸铝是一种新型的复合材料。本文系统地介绍了该材料的发展、制备工艺和性能,并讨论了影响石墨飘浮的因素。指出,石墨铸铝复合材料具有较小的膨胀系数,良好的减磨性和抗震性能。因此,它是制造内燃机活塞和滑动轴承的理想材料。更多还原

【Abstract】 AbstractCast Al-Gr.alloy is a new kind of composite material.In this paper the dovelopment,preparing process and properties of Al-Gr Composite material have been systematicallyintroduced. The factors effecting on the floating of graphite particles have also beendiscussed.It is indicated that Al-Gr composite material has little coefficient of expansiongood antifriction and antiviberation. properties. Therefore it is an ideal matorial forpreparing piston in internal-combustion engine and sliding bearing.更多还原
