Abstract:

Magnesium alloys are one of the most promising lightweight structural materials. Nevertheless, the poor corrosion and wear resistance of magnesium alloys restrict their applications. As a surface modification technology, laser cladding can effectively improve the surface properties of magnesium alloys because of its unique high efficiency and metallurgical combination of coating and substrate. Due to the characteristics of magnesium alloy, laser processing parameters and material selection are of vital importance to improve the surface properties of magnesium alloys. The influence of laser cladding process parameters (laser power, scanning speed and wavelength) is discussed in detail, and the main material systems for laser cladding of magnesium alloys are summarized. In addition, the development and status of laser cladding of magnesium alloys are discussed, and the main problems of laser cladding of magnesium alloys are put forward. The future development of laser cladding of magnesium alloys is predicated.
