    Abstract

    Tantalum has physical and chemical properties that are well suited for use in medical implants. However, a lack of bone induction prevents this biologically inert material from combining well with bone tissue. This study reports the successful preparation of a micro-arc oxidation (MAO) coating on tantalum in phosphate solution. The porous surface of the coating includes uniformly distributed craters. Its constituent elements are evenly dispersed. Tantalum is present in the coating as tantalum pentoxide. In vitro testing of the coating with MG63 osteoblasts showed it has good biocompatibility and can promote cellular adhesion and proliferation. MAO coating on tantalum represents a new and potentially useful method to improve the clinical applicability of tantalum.
