The hob is an important tool for the shield machine, which improves its wear resistance and is of great significance for extending its life and improving the reliability of the shield machine. Based on the working condition of the hob, Ni-Cr-B-Fe surfacing flux-cored wire was designed. The effects of Ni and B content on the microstructure and properties of deposited metal were studied by XRD and SEM. Optimize Ni and B content to provide technical data. The powder 40%Ni-10%Cr-50%Fe-B alloy flux-cored wire studied was used for hob surfacing, which significantly improved its wear resistance.
