Laser cladding technology has been proved an effective method to remanufacture the damaged parts by cladding high performance materials. The type of alloy powders, laser output power, and scanning speed were selected as influencing factors to conduct orthogonal cladding experiment on the substrate of carbon steel C45. Bonding shear strength and micro hardness of the clad layer and the substrate was tested and analyzed. Metallography of the clad layer was evaluated by scanning electron microscope (SEM) image. The experimental results show that a good metallurgical bond is formed between the clad layer and the substrate without porous cracks and other defects.
