چکیده
|
In the past, damaged tissue was removed from the patient's body. but now tissue regeneration using scaffolds and implants are used to repair the damaged tissue and organs. besides the mechanical properties of metallic biomaterials, they suffer from bioinertness. using some surface treatment techniques, the bioactivity and also corrosion resistance of titanium implants could be improved. in this study, the effect of h2o2 and alkali treatments on the corrosion behavior of titanium implant in the artificial saliva, surface morphology and phases formed on the surface, was investigated using electrochemical corrosion test, scanning electron microscopy (sem) and thin film x-ray diffractometry (tf-xrd), respectively. the results indicated that on the surface of h2o2 and alkali treated titanium samples, fine particles of anatase and fine wires of rutile were formed, respectively. the results revealed that the corrosion resistance of alkali treated titanium in the artificial saliva was higher than that of the h2o2 treated titanium sample. the corrosion current density for the untreated, h2o2 and alkali treated titanium samples was about 0.6×10^-8, 5×10^-8, 3×10^-8a/cm^2, respectively.
