摘要
铝合金气缸的表面硬度及耐磨性能不好,为了提高其表面硬度及耐磨性能,改善其高温性能,本文利用改质材料经过摩擦作用发生塑化和塑性流动后形成改质层的原理,对铝合金气缸内表面的摩擦改质工艺进行了研究。研究结果表明,在铝合金气缸内表面采用Al-Si 13%合金和Al-Cu 35%合金作为改质材料经过摩擦改质处理后,可形成比较稳定的硬质膜,涂覆层的细化更加均匀,结合界面和气缸内表面的形状都非常圆滑,改善了气缸的耐磨性,有利于发动机的小型轻量化。
The performance of Al alloy cylinder at high temperature largely depends on its inner surface hardness and wear resistance.In order to increase the surface hardness and strengthen the wear resistance,this paper researches the process of coating friction of Al alloy cylinder by using for reference the principle which the surface modified material through friction plasticizes and the plasticized flow of the surface morphology forms a modified layer.The results show that the inner surface of the Al alloy cylinder using Al-Si 13%alloy and Al-Cu 35%alloy as modified friction modified material can form more a stable horniness membrane with a thinner and more uniform coating layer and a very sleek interface and inner surface of cylinder shape.Thus the wear resistance of the cylinder is improved to make engines more small-sized and light weighted.
