Estimating the Functional Properties of Thin Calcium-Phosphate Coatings on Medical Implants

摘要

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 com pliance with GOST (State Standard) 9.302. Thin CP coatings on specimens subjected to sand blasting endured shear loads better in comparison with bending ones.
