功能性钎涂技术的研究进展与应用现状

As one of the important methods to modify the surface of materials and prolong service lives of key structural components, brazing coating technology had been widely applied in aerospace, agricultural machinery, oil drilling and other fields. The relevant researchers had performed extensive study in the field. In this paper, the relevant studies on biomimetic brazing coating technology in the past two decades are reviewed. Firstly, the research status on biomimetic brazing coating technology is summarized. Secondly, the preparation processes and properties regulation of carbide/Ni, carbide/Cu, carbide/Fe, carbide/Ag brazing coating technology are expounded in detail. Additionally, the applications of brazing coating technology in the field of surface modify of aerospace, agricultural machinery, oil drilling components are introduced. Finally, the current problems and shortage of the brazing technology are pointed out and the future development direction of brazing technology is expected. This aim of this paper is to provide the theoretical guide and reference for the research of functional brazing coating technology based on the summary of relevant researches.
