| Abstract: |
| High boron Fe-based alloy is a Fe-based wear-resisting material with in-situ formation of boride. It has the advantages of high hardness, high temperature stability and low cost. In recent years, it has been widely studied. In this paper, the research progress of high boron Fe-based wear-resistant cladding coating in recent years was systematically reviewed from two aspects of material system and preparation technology of cladding layer. Firstly, three high boron Fe-based material system (Fe-B-C, Fe-B-Cr-C, Fe-B-Cr-Mo-C) were introduced. The interaction law between the alloy components and the type, morphology and distribution of in-situ boride hard phase was described. The micrograph of borides with the change of components content was given. The effects of components design and heat treatment process on the microstructure evolution and wear resistance of the alloy were summarized. At the same time, the influence of other elements on the microstructure and properties of high boron Fe-based alloy was analyzed. And then the preparation technology of high boron Fe-based wear-resistant cladding was introduced, including plasma cladding, laser cladding, electron beam cladding and argon arc cladding. The feasible improvement methods of cladding technology were analyzed, such as compound heat source and applied magnetic field. The influence of the preparation technology on the cladding layer was discussed. In addition, the research direction and the application prospects of high boron Fe-based alloy cladding were forecasted. |
