Research status of the transition layer on laser cladding.

Laser cladding technology is widely used in component repair and surface strengthening because of its advantages of various powder options and high processing efficiency. This paper outlines the application and research of transition layers in laser cladding and details the advantages of transition layers in terms of bonding performance, defect rate, and cladding thickness. Compared with conventional laser cladding, the composite process with the addition of transition layer has been further improved in terms of organization, mechanical properties, and corrosion resistance. In addition, the repair process of laser cladding to meet the cladding thickness of the parts and avoid the degradation of surface properties is also discussed. [ABSTRACT FROM AUTHOR]
