Abstract:
Evaporation of calcium on commercially pure titanium was performed. Heatings under vacuum or oxygen flow improved calcium diffusion in the titanium substrate. X-Ray Photoelectron Spectroscopy did not revealed any superficial segregation of titanium but revealed the formation of CaCO3. The film formed on titanium was characterized using X-ray photoelectron spectroscopy with argon-ion sputtering. The results indicated that: the surface layer consisted of CaCO3; the interface contained CaCP3, CaO et TiO2; only CaO was present in the bulk titanium.
