Abstract

Wear is one of the main failure forms of metal parts， and the surface coating technology is one of the important methods to protect metals from wear. TiC-TiB2 dual-phase composite wear-resistant ceramic coating is widely used as a protective coating for material surface due to dual advantages of carbide and boride ceramics，such as higher hardness and better wear and corrosion resistance. In this paper，the research progress of in-situ TiC-TiB2 composite coating was reviewed from two aspects: preparation method and main metal binders of TiC-TiB2 coating.The advantages and disadvantages of different preparation methods for TiC-TiB2 coating were compared， and the problems and possible solutions in practical applications were referred. The synthesis mechanisms and the reasons for improving the performance of TiC-TiB2 coating after adding different metal binders were summarized. The advantages and disadvantages of various metal binders in actual applications were analyzed. Finally， the future optimization directions and urgent problems of the preparation process of TiC-TiB2coating were pointed out.

Key words： TiC-TiB2; ceramic coating; preparation method; metal binder; wear
