The steel-bonded cemented carbide combines the excellent mechanical properties of alloy steel with the high wear resistance and hardness of cemented carbide,offering a compelling cost-performance ratio.Achieving a strong metallurgical bond between the steel-bonded cemented carbide and the metal substrate of large-scale wear-resistant components has become a key technological challenge in enhancing the overall wear resistance and service life of equipment.This article summarizes the different metallurgical bonding forms,principles,and characteristics of steel-bonded cemented carbide with steel,and provides an overview of the research achievements in this field by scholars at home and abroad in recent years.It specifically introduces the research status of connection methods such as casting-in,brazing,diffusion welding,laser welding,and arc welding,and summarizes the applicability and existing issues of these connection methods in practical usage,with a particular focus on statistical data and analysis of the interface bonding between steel-bonded cemented carbide and the steel substrate.Finally,through summarizing existing technologies,the article outlines future research and development directions for achieving a robust metallurgical bond between steel-bonded cemented carbide and the steel substrate.
