EFFECT OF CU2+ AND ZN2+ INCORPORATED INTO FLUOROHYDROXIAPATITE COATING ON CoCrMo ALLOY WITH ANTIMICROBIAL PROPERTIES

The present study reflected antibacterial properties of a coating based on fluorohydroxyapatite (FHA)/with Cu2+ and Zn2+ ions on CoCrMo alloy in phosphate buffered saline (PBS) medium. The coating structure was identified by Fourier transformed infrared spectroscopy (FTIR) and the surface analysis of phosphate deposits by quantifying the hydrophilic / hydrophobic balance and the roughness by AFM determinations.Cu2+ and Zn2+ ion release was studied using inductively coupled plasma mass spectrometry (ICP-MS) method. Antibacterial properties of coatings were determined by contact method using using agar disc diffusion method for two bacterial strains: Staphyloccoccus aureus and Pseudomonas aeruginosa.
