SHEN LIDA / GU JIAJUN / LIU QINGRONG

The invention discloses a preparation method of a porous biological ceramic coating with controllable porosity, and relates to the technical field of preparation of biological ceramic materials and ceramic coatings. The method comprises the following steps: (1) mixing biological ceramic powder with a pore-forming agent to obtain biological ceramic composite powder; (2) adding the composite powderand other assistants into photosensitive resin in proportion to prepare light-curing ceramic resin slurry; (3) coating the surface of a matrix with the light-curing ceramic resin slurry, and performing light curing to obtain a porous biological ceramic coating green body; and (4) degreasing the porous biological ceramic coating green body at high temperature, removing the pore-forming agent and performing sintering to obtain the porous biological ceramic coating. The method is simple, convenient and easy to operate, and the biological ceramic coating with controllable porosity and uniform tissue structure can be prepared by designing and optimizing the composition and proportion of the light-curing ceramic slurry and using a photocuring forming mode.
