Bioactive Bilayer Glass Coating on Porous Titanium Substrates with Enhanced Biofunctional and Tribomechanical Behavior

The use of porous titanium samples fabricated by space-holder powder metallurgy with bioactive coatings has already been reported to prevent resorption the bone surrounding implant and improve osseointegration, respectively. However, presence pores as well poor adherence brittle behavior inherent glassy affect service implants from these samples. Therefore, they need be optimized. In this work, 50 vol.% porosity substrates were manufactured different pore range size (100–200 355–500 µm) spacer particles coated a bilayer glasses (45S5/1393). effect on tribomechanical properties infiltration glass 1393 along bioactivity 45S5 evaluated instrumented micro-indentation scratch tests formation hydroxyapatite in simulated body fluid. results obtained very promising potential for replacement small tumors cortical tissues, mainly due smaller that present an improved biomechanical biofunctional balance.
