METHOD FOR PREPARING NANOSTRUCTURED CALCIUM-PHOSPHATE COATING FOR MEDICAL IMPLANTS

摘要

FIELD: medicine.SUBSTANCE: what is described is a method for preparing a nanostructured calcium-phosphate coating for medical implants consisting in sputtering a target of stoichiometric hydroxyapatite Ca(PO)(OH)in high-frequency magnetron discharge plasma in the argon environment under pressure of 0.1-1 Pa and target power density of 0.1-1 W/cmfor 15-180 min at a distance from the target to a carrier within the range of 40 to 50 cm, wherein the nanostructure is formed after a coating procedure in the process of the controlled thermal annealing at a temperature of 700-750°C for 15-30 min.EFFECT: higher post-coating effectiveness of the production process.4 dwg
