dc.description.abstractThe purpose of this work was to evaluate the Ti-35Nb-7Zr experimental alloy after surface treatment and soaking in solution body fluid (SBF) to form bonelike apatite. The Ti-35Nb-7Zr alloy was produced from commercially pure materials (Ti, Nb and Zr) by an arc melting furnace. All ingots were submitted to sequences of heat treatment (1100 °C/2 h and water quenching), cold working by swaging procedures and heat treatment (1100 °C/2 h and water quenching). Discs with 13 mm diameter and 3 mm in thickness were cut. The samples were immersed in NaOH aqueous solution with 5 M at 60 °C for 72 h, washed with distilled water and dried at 40 °C for 24 h. After the alkaline treatment, samples were heat treated in both conditions: at 450 and 600 °C for 1 h in an electrical furnace in air. Then, they were soaking in SBF for 24 h to form an apatite layer on the surface. The surfaces were investigated by using scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), infrared spectroscopy (FTIR) and contact angle measurements. The results indicate that calcium phosphate could form on surface of Ti-35Nb-7Zr experimental alloy. © Springer-Verlag Berlin Heidelberg 2013.en
