Description

technical field

[0001] The invention relates to a magnesium alloy surface remelting surfacing welding method, in particular to a magnesium alloy surface SiC+Al surfacing welding method, which is used in the field of welding technology. Background technique

[0002] Magnesium and magnesium alloys have light specific gravity, and magnesium alloy has high specific strength and specific stiffness, good thermal and electrical conductivity, good damping and shock absorption and electromagnetic shielding performance, and is easy to process and shape, easy to recycle waste, and less environmental pollution. Replace steel and aluminum alloy structural parts in aviation, transportation and other industries, thereby reducing weight and improving energy efficiency. However, magnesium alloy has low hardness, poor wear resistance, active chemical properties, and no corrosion resistance, which greatly limits its application range. Ceramic materials can be used as the surface coating of th...
