The enhanced characteristics of osteoblast adhesion to porous Zinc-TiO2 coating prepared by plasma electrolytic oxidation

► Porous Zn-TiO2 coating was prepared by plasma electrolytic oxidation in a novel Ca, P, Zn-containing electrolyte. ► Characteristics of the Zn-containing TiO2 coating were investigated. ► Adhesion of MC3T3-E1 cells on Zn-TiO2 coating, as well as its possible signal transduction pathway involved are discussed.
