Analyzing the corrosion and tribocorrosion performances of monolayer TiO₂ and bilayer TiO₂-SiO2 coatings at different SBF temperatures

Abstract

In this study, using commercial pure titanium (Cp-Ti) samples, monolayer TiO2, and bilayer TiO2-SiO2 coatings were produced. The aim of this study is to compare the effect of monolayer and bilayer coatings on corrosion and tribocorrosion behaviors of the preferred Cp-Ti material which is preferred especially in applications such as dental implants at different temperatures in simulated body fluid (SBF). XRD and SEM were used for the structural characterization of the coatings. Then, the adhesion strengths of monolayer and bilayer coatings were investigated. Corrosion and tribocorrosion performances of the coatings were carried out at different temperatures due to the change in oral environment temperature due to hot food and drinking consumption. Adhesion strengths corrosion and tribocorrosion performances of untreated, monolayer, and bilayer Cp-Ti samples were examined, and the best performance was seen in the bilayer coatings.

Experimental study on effect of deformation temperature on mechanical and biological activities of Ti-6Al-7Nb titanium alloy

“…The surface reactivity of a material, including its ability to support the formation of a HA layer, is crucial in SBF treatment. Higher deformation temperature might influence the surface structure, composition, or defects, affecting the materials reactivity with the SBF solution [25,26]. The effect of deformation temperature on the biological activities of titanium alloys in simulated body fluid is considered.…”
