| Abstract Scope |
Functionalization of metallic surfaces for prostheses helps to improve osseointegration as well as wear and corrosion resistance, among other properties. This work describes the use of electron beam (EB) structuring and Plasma Electrolytic Oxidation (PEO) to control the surface topography and the bioactivity of Titanium alloys. Surface structures are designed following different criteria to develop a multiscale topography on the substrate. The molten pool and the fast cooling generated by EB structuring provoke a change in the microstructure. PEO coatings with different Ca/P ratios are successfully formed on the EB structured titanium surfaces. The increment of the treatment time affects the roughness, the Ca/P atomic ratio, and the pore morphology at the surface of the material. The original structured topography produced by EB remains well preserved. Furthermore, the corrosion behavior of the coated specimens is evaluated in physiological media. |
