Abstract: Laser cladding technology is a new type of surface modification technology, it is helpful to improve the corrosion resistance of the material matrix, which is beneficial to increase the service life of the materials and reduce the manufacturing cost. The recent development of laser cladding technology was mainly summarized, including laser cladding equipment, the process flow of laser cladding, and the advantages and disadvantages of laser cladding technology. The various widely used cladding layer materials（nickel-based, cobalt-based, iron-based self-fluxing alloy powders, ceramic powders,composite powders） and ultrasonic vibration assisted technology were briefly introduced, and the future development direction of laser cladding technology was prospected.
