摘要
A novel restraint spraying-Conform (RS-C) process, which directly combines spraying with Conform to process metals in one step, has been proposed. Al-20Si alloy selected as experimental material was successfully fabricated by the RS-C process. The microstructures were dominated with fine and uniform primary silicon phases. The tensile strength and elongation to failure of the Al-20Si alloy were 204 MPa and 7.2% respectively after the RS-C process. The wear resistance of the processed Al-20Si alloy was increased significantly, about 1.7 times over the as-cast ingot. The experimental results indicate that RS-C is a promising near net shape forming technology.
