Influence of High-Frequency Micro-Forging on the Surface Microstructure and Cracking Behavior of Laser Cladding
This paper utilized self-made high-frequency micro-forging machine to treat NiCrBSi alloy cladded by laser, Optical Microscopy(OM) to study geometric characteristic of plastic deformation, OM and SEM to observe influence on surface microstructure and cracking behavior of the laser cladding layer under micro-forging. The results have shown that: Regularly dendrite microstructure, which is peculiar of laser cladding layer, was broken into pieces. Cracking behavior of laser cladding layer improved greatly.
