Abstrakt:	The structure of the silver-substituted hydroxyapatite and tricalcium phosphate powders is confirmed by the methods of X-ray phase diffraction analysis and IR spectroscopy. Silver-substituted hydroxyapatite coatings consist of large particles of round shape and the presence of nanoparticles is also detected. The silver-substituted tricalcium phosphate coatings are formed by fine particles and nanoparticles are detected on the entire surface of the coating. Both types of coatings exhibit hydrophilic properties. The adhesion of silver-substituted tricalcium phosphate coatings is almost twice higher than the adhesion of silver-substituted hydroxyapatite powder coating. The obtained coatings are of interest as antimicrobial coatings for intraosseous dental and orthopaedic endoprostheses. [ABSTRACT FROM AUTHOR]
