Abstract

Because of the superior chemical and mechanical properties of titanium, many surface treatments have been developed to alleviate its bioactivity limitations. Among all these, the procedures involving the modification of the surface of the titanium using liquid media have received more attention, because of their ability to modify all outer and inner pores of porous titanium implants. In this research, both rigid and porous titanium implants were surface treated using hydrogen peroxide and the effects of treatment on surface morphology and the weight change of the rigid implant and the mechanical properties of the porous implant were investigated using scanning electron microscope (SEM), balance, and compression tests, respectively. The results indicated that although this procedure was a corrosive phenomenon leading to the surface roughening of rigid samples and influencing cell adhesion positively, it also resulted in about 34% reduction in the mechanical properties of the porous titanium implant. © 2016 Elsevier B.V.
