Calcium Phosphate Formation on Ti-Ag Alloys in Simulated Body Fluid

Journal of Biomechanical Science and Engineering, 2009
Ti-Ag alloys with 20 and 25 mass% Ag were prepared; their surfaces were polished using silicon carbide abrasive papers. The polished alloys were immersed in a simulated body fluid (SBF), and their surfaces were observed by scanning electron microscope ...
