Microstructure and mechanical properties of GH3536 alloy were examined using laser cladding deposition (LCD) forming technology on the surface of forged GH3536 alloy. The results show that an equiaxed crystal junction zone with a width of 250-320 μm is formed between the laser forming zone of the LCD forming GH3536 alloy and forged substrate. Additionally, the width of the molten pool in the forming zone is 2-2.5 mm. There is a dendritic structure and a few hole defects in the molten pool. The continuous distribution of M₆C and M₂₃C₆ carbides precipitated in the bonding and forming zones during the forming process. The LCD forming GH3536 exhibits evident anisotropy since the GH3536 alloy in the forming zone has a higher room temperature tensile strength than the base material.The tensile and yield strength of the material perpendicular to the forming direction are 12.5% each higher than the material parallel to the forming direction. Although, it is 9.1% longer and its elongation is 7.7% less. Its Vickers hardness is 12.4% lower than the base material owing to the large grain size of the GH3536 alloy in the laser forming zone and few hole defects.
