【Abstract】 Al--17Si--2Cu--1Mg alloy plate blank was produced by Multi--Layer Spary Deposition Technology. The effect of over--heat temperature of molten alloy and cooling conditions on microstructure of deposits was studied. The relationship between the substrate materials, temperature and the adhering results of the deposits, and the substrates was discussed and proper processing was proposed.更多还原
