description The invention discloses a preparation method of a beta-tricalcium phosphate nanometer coating. The preparation method comprises the following steps: (1) adding dispersant in a calcium source solution, uniformly stirring, adding a phosphorus source solution dropwise, and continuously stirring, ageing, filtering, washing, freezing, drying and calcining the mixture to obtain a beta-tricalcium phosphate powder; (2) adding the prepared beta-tricalcium phosphate powder in ethanol, carrying out ball milling and standing to prepare a stable beta-tricalcium phosphate suspension; and (3) taking a gold sheet as a working electrode, a platinum electrode as a counter electrode and the beta-tricalcium phosphate suspension as an electrolyte, applying direct current between the electrodes, and carrying out electrophoretic deposition on the surface of the gold sheet to obtain the beta-tricalcium phosphate nanometer coating. According to the preparation method, phase change and embrittlement caused in the high temperature proc
