Abstract

Serious wear failure of agricultural machinery soil-engaging components has always been an industry problem to be solved. Braze coating technology,as a new direction in AM（Additive Manufacturing）,has brought new breakthrough in recent years. Heterogeneous brazing technology is used to optimize the materials of soil contacting parts to greatly improve their wear resistance,which is of great significance for improving working efficiency and fostering green transformation of agricultural machinery. This paper summarized the application status and limitations of heterogeneous additive technologies such as overlay welding,thermal spraying,spray welding,and cladding for agricultural machinery soil-engaging components,focused on the application advantages of wear-resistant coating for soil-engaging components based on braze coating technology,and explored the existing problems and development direction of soil-engaging components coatings by braze coating technology.
