Abstract

The present invention relates to a method for constructing a whitlockite coating on a surface of a calcium phosphate-based bioceramic substrate and a resulting coating, wherein the preparation method includes the following steps of: preparing pure calcium phosphate-based bioceramic powder firstly, then pre-firing, shaping and calcining the pure calcium phosphate-based bioceramic powder to obtain a calcium phosphate-based bioceramic substrate, placing the substrate in a solution containing Mg, then transferring the substrate to a high-temperature high-pressure reaction kettle for a hydrothermal reaction, and then cleaning and drying the sample to obtain a whitlockite coating.
