“…Its content in the earth's crust is as high as 7.73%, ranking third, following only oxygen and silicon, which makes it the most abundant of the metallic elements. The tensile strength of pure aluminum (with an aluminum content not less than 99.60%) is 70-130 MPa, its elongation rate is 6-43%, and its hardness is 35 HB [2][3][4][5][6][7][8][9]. An aluminum alloy is made by adding some other elements to pure aluminum.…”

As one of the lightest structural metals, the application breadth of aluminum alloys is, to some extent, constrained by their relatively low wear resistance and hardness. However, laser cladding technology, with its low dilution rate, compact structure, excellent coating-to-substrate bonding, and environmental advantages, can significantly enhance the surface hardness and wear resistance of aluminum alloys, thus proving to be an effective surface modification strategy. This review focuses on the topic of surface laser cladding materials for aluminum alloys, detailing the application background, process, microstructure, hardness, wear resistance, and corrosion resistance of six types of coatings, namely Al-based, Ni-based, Fe-based, ceramic-based, amorphous glass, and high-entropy alloys. Each coating type’s characteristics are summarized, providing theoretical references for designing and selecting laser cladding coatings for aluminum alloy surfaces. Furthermore, a prediction and outlook for the future development of laser cladding on the surface of aluminum alloys is also presented.
