Research on Aluminum Alloy Cylinder Internal Surface Friction Coating Treatment Process
The performance of Aluminum alloy cylinder at high temperature largely depends on its inner surface hardness and wear resistance. In order to improve its surface hardness and strengthen the wear resistance, the process of coated friction of Aluminum alloy cylinder are studied by using for reference the principle which the surface coating material through friction plasticizing and the plasticized flow of the surface morphology forms a modified layer. The results show that the inner surface of the Aluminum alloy cylinder using Aluminum -Si13% alloy and Aluminum -Cu35% alloy as modified friction coating 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 after processing. Thus the wear resistance of the cylinder is improved to make engines more small-sized and light weighted.
