METHOD FOR MAKING SUPPORTED CALCIUM-PHOSPHATE COATING

摘要

FIELD: medicine. ^ SUBSTANCE: invention refers to the method for making bioactive calcium-phosphate coatings and can be used in manufacturing of orthopaedic and tooth prostheses. The method for making supported calcium-phosphate coating involves radio-frequency magnetron sputtering of hydroxyapatite target Ca10(PO4)6(OH)2 during 15-150 min with using argon as a working gas at pressure in a working chamber 0.1 Pa. The coating is settled over a support over a ring of magnetron cathode region, where field lines of magnetron magnetic field localise high-frequency plasma with maximal effect of charged particle on the support at specific power of high-frequency discharge 50 W cm-2 that provides formation of coating composition close to that of stoichiometric hydroxyapatite Ca10(PO4)6(OH)2. ^ EFFECT: application of the method ensures activation of coating crystallisation during growth with final phase formation that corresponds to composition of the target. ^ 6 dwg, 3 ex
