Resumen
Polycrystalline calcium titanate films up to 300 nm in thickness were grown
on titanium and Ti6Al4V substrates by the hydrothermal–electrochemical
technique in an autoclave at 200 ◦C. The films examined by x-ray diffraction
exhibited reflections from orthorhombic calcium titanate on both substrates.
The analysis by x-ray photoelectron spectroscopy showed calcium, titanium
and oxygen at binding energies consistent with calcium titanate. The films
grown on Ti6Al4V exhibited a small aluminium content but no vanadium. All
films showed magnesium incorporation equivalent to a few per cent of the
calcium content, which can be useful for the eventual use of the coating for
biocompatible applications.
