TiB_2 is the most stable compound of the transition element Ti and the element B, and is one of the ad- vanced ceramic materials, which possesses a series of excellent properties as high abrasion resistance, high erosion resistance, high temperature resistance, oxidation resistance and so on, but it is rather difficult to utilize as the construction material directly for its high brittleness and difficult fabrication. The coatings con- taining the TiB_2 fabricated by various technologies can both haave the excellent performance of TiB_2 material to satisfy the require- ments of working pieces such as wear resistance, erosion resist- ance, high temperature resistance and so on, and at the same time it can save the material and the cost. Especially the thermal spraying technology has become the keystone to fabricate the TiB_2 coatings because of its simpleness and agility. The configuration and performance of the advanced ceramic material TiB_2 were in- troduced firstly, and the main methods of fabricating the TiB_2 coatings were presented. The stress was the research advancement and achievement of thermal spraying TiB_2 ceramic coatings at home and abroad. Afterward, the characteristics and developing current of different thermal spraying technologies were analyzed and discussed. Finally the successful application and wide devel- opment potential of TiB_2 coatings were recommended.
