The invention discloses a hydrophilic bioactive ceramic coating material for biomimetic biomineralization osteogenesis. The material comprises an HA/BaTiO3 composite layer. The invention further discloses a preparation method of the composite material, and the composite material is prepared by adopting a broadband laser cladding method. BaTiO3 is introduced into a traditional bioactive ceramic coating material to form an HA/BaTiO3 composite layer, a bioelectric microenvironment is constructed in situ to prepare a hydrophilic bioactive ceramic coating, effective combination of electrical stimulation and an artificial joint coating is realized, and the piezoelectric effect of piezoelectric electric charges and inorganic salt ions in body fluid is utilized to effectively improve the mechanical property of the artificial joint. Inorganic salts of calcium and phosphorus are adsorbed to the surface of the coating, so that an osteogenesis environment is created for osteogenesis of a life body, the hydrophilic perfor
