Abstract

The preparation methods and development trend of ZrB2-based composite coating were reviewed. The technical advantages and applications of thermal spraying technology in the preparation of ZrB2 based composite coating were introduced, summarized and prospected. The reaction synthesis of ZrB2 based composite coating by thermal spraying can solve the problem of poor melting state caused by the high melting point of raw material and improve the quality and properties of the coating. The design of precursor powder composition is one of the key factors to make the ZrB2 based composite coating prepared by thermal spraying reaction synthesis to meet the ideal application requirements. The problems to be considered in the composition design and optimization of precursor powder are also put forward.
