We have investigated nine patients with cemented Furlong (JRI, London, UK) titanium hip replacements who presented with early pain despite a well-fixed, aseptic prosthesis. All were followed up clinically and radiologically at regular intervals. Pain was located in the thigh and was worse at night. Radiographs showed cortical hypertrophy of the femur around the tip of the stem. Eight of the nin...

Titanium and its alloys have been widely used as implant materials due to their excellent mechanical property and biocompatibility. In the present study, the effect of glucose concentration on corrosion behavior of pure titanium TA2 in Hanks' simulated body fluid is investigated by the electrochemical impedance spectrum (EIS) and potentiodynamic polarization methods. The range of glucose concen...

The effects of Cr, Mo and W on the crevice corrosion of a number of commercial Ni-Cr-Mo (W) alloys in 1.0 mol/L NaCl were studied using the potentiodynamic-galvanostaticpotentiodynamic technique to measure film breakdown and repassivation potentials as well as protection temperatures. As expected, Cr is the key element determining resistance to crevice initiation but a substantial Mo alloy cont...

In the present study we performed anodization of stainless steel AISI 316L varying voltage, time and H 2 O concentration in electrolyte obtaining self-ordered porous oxides. Open-circuit potential measurements, potentiodynamic polarization electrochemical impedance spectroscopy were 0.1 M SO 4 , NaCl NaOH electrolytes. The metallic substrate underneath grown oxide was also characterized. result...
