METHOD OF OBTAINING COMPOSITE POROUS BIOACTIVE COATING Russian patent published in 2017 - IPC C23C4/12 C23C4/04 

FIELD: chemistry.

SUBSTANCE: method of producing a composite porous bioactive coating includes spraying a substrate on a first stage of a metal coating layer at an angle to the substrate greater than 45°, deposition on it in the second stage of a layer of the same metallic material at an angle to the substrate less than 45° and spraying onto the layers obtained in the third stage of the bioactive ceramic layer. The layers are sprayed on all three stages at a substrate temperature of 200-900°C, and the bioactive ceramic layer is sprayed in the third stage at angles of 45-90° to the surface of the metal coating layer formed in the second sputtering stage.

EFFECT: increase in the shear strength of the composite coating while maintaining its porosity of 10-60 percent and a pore size of 10-600 mcm.
