Surface microstructure and cell compatibility of calcium silicate and calcium phosphate composite coatings on Mg-Zn-Mn-Ca alloys for biomedical application

▶CaSiO3/CaHPO4·2H2O composite coating has been prepared onto Mg-Zn-Mn-Ca alloy. ▶ The composite coating is nontoxic. ▶ The composite promotes the osteoblasts adhesion and cycle stage. ▶ The composite coating improves the anti-corrosion property.
