Abstract

Zirconium dioxide ceramic coatings were applied to the surface of 316L steel using the sol-gel method. The coated samples were heated at 300 °C or 500 °C. The task of the coatings was to increase the bioactivity and corrosion resistance of 316L steel in the SBF (simulated body fluids) environment. Examination of the chemical composition (EDS, Raman spectroscopy) of these samples after 150 days of exposure showed an increased presence of phosphates on the surface compared to uncoated steel samples. The deposition of ZrO2 coatings also increased the corrosion resistance of 316 L steel in the SBF solution (electrochemical tests).
