Abstract

The paper reports the results of depositing SiO2 and SiO2-TiO2 coatings on titanium alloy Ti-6Al-4V ELI (ASTM-grade 5). Oxide coatings were deposited onto the titanium alloy substrate by sol-gel method and by electrophoresis. The produced coatings were chemically uniform, compact and highly dense. We then performed SEM microstructure examination, as well as microhardness and surface roughness measurements for different coating combinations. The significance of the results was assessed by the Shapiro-Wilk and t-Student tests using the STATISTICA software. It has been found that there are statistically significant differences in the hardness of SiO2 and SiO2-TiO2 coatings. The results of roughness parameters reveal significant differences only for individual coatings.
