The experiment on continuously purifying of aluminumbasealloy melt by travelling magnetic field was carried out. The trajectory model was used to calculate the inclusion removal efficiency.
In salt lake, the alclad on LC4 aluminumalloy remaindered for half a year, and used up for one year. The base of LC4 aluminumalloy was corroded seriously.
According to the liquid separation property of Cu-basealloy, the Cu-base coating is obtained on the aluminumalloy by CO2 laser cladding for improving the surface strength of aluminum alloy.
