| 摘 要： | 首次研究了Ａｌ６５Ｃｕ２０Ｃｒ１５准晶颗粒／Ａｌ基复合材料的硬度及摩擦学性能。研究表明，该复合材料的硬度随准晶颗粒体积分数的增加而增加，最大达到１２００ＭＰａ，最纯铝的４倍。复合材料的摩擦学性能优于纯铝，当准晶颗粒体积分数为１５％￣２０％，摩擦学性能随体积分数的升高而改善，当体积分数达到２５％时，摩擦学性能有所降低。

| Abstract: | In this paper the tribological properties and hardness of Al 65Cu 20Cr 15 quasicrystalline particles/Al composite alloys are reported. It was found that the hardness of the alloys increases with increasing volume fraction of quasicrystalline particles and the maximum hardness is as high as 1 200 MPa, being 4 times of that of Al. At our test conditions, frictional coefficient and wear rate are lower than that of Al and decrease with increasing volume fraction of quasicrystalline particles in a range from 15% to 20%, when volume fraction reaches 25%, the frictional coefficient and wear rate increase to some extent. |
