Abstract The process of diamond induction brazing has a great influence on the microstructure and property of the steel substrate.Post brazing heat treatment is an important method to improve the performance of the substrate, but it also has great impact on the coating. The influence of post heat treatment on the hardness and microstructure evolution of induction brazing nickel base alloy coating was investigated by means of high temperature microscope, SEM, XRD, hardness testing and other analytical methods. The results show that the NiCrSiB brazing coating structure was mainly composed of Ni solid solution, CrB, Ni₃Si, Ni₃B, and Ni-Ni3Si eutectic phases. After quenching treatment, the content and dimension of Ni₃Si-Ni solid solution eutectic crystals decreased, the CrB phase grew to a certain extent, and the total content of Ni₃Si phase reduced. After tempering treatment, the content of the eutectic structure near the grain boundary of the NiCrSiB brazing coating increased, and CrB phase grew further to promote the formation of little Ni₃Si phase. The hardness of the brazed state coating was higher, then it decreased integrally after quenching and rose again after tempering. A novel technology of brazing and coating combined with heat treatment to improve the comprehensive performance of the rotary cultivator was developed, based on the rotary blade for agricultural machinery equipment as the specific object.
