Nanoindentation results revealed that the surface hardness of 316L stainless steel increased markedly after coating with CuAlO 2 films. Electrochemical tests of corrosion potential, breakdown potential, and corrosion current density showed that the corrosion resistance properties of 316L stainless steel are considerably improved by CuAlO 2 coatings. Bicinchoninic acid (BCA) protein assay results revealed that the protein adsorption behavior of 316L stainless steel did not exhibit notable differences with or without CuAlO 2 coatings. A CuAlO 2 coating of 100 nm thickness improved the surface nanohardness and corrosion resistance ability of 316L stainless steel. CuAlO 2 is a potential candidate for biomaterial coating applications, particularly for surface modification of fine, delicate implants. ? 2013 Elsevier B.V. |
