Estimating the functional properties of thin calcium-phosphate coatings on medical implants

Research output: Contribution to journalArticle

Abstract

Thin calcium-phosphate (CP) coatings were formed on the models of medical products by radio-frequency (RF) magnetron sputtering. Using microscope studies, the coatings were shown to be visually continuous without visible pores and cracks. The functional properties of thin CP coatings were estimated by the method based on the measurement of the disruptive electrical voltage in compliance with GOST (State Standard) 9.302. Thin CP coatings on specimens subjected to sand blasting endured shear loads better in comparison with bending ones.
