INVESTIGATION BIOMEDICAL CORROSION OF IMPLANT ALLOYS IN PHYSIOLOGICAL ENVIRONMENT

A biomaterial could be any material, which is designed for medical application inside human body for medical purposes such as treat, augment, repair or replace a tissue function of the body. And, these materials became very common in the ten recent years, and Ni-Ti alloys is considered as one of the metals that is used for biomedical applications. For long period, the biomaterials are very limited materials and these materials are very expensive such as bioinert titanium based alloys, stainless steel, alumina and zirconia ceramics. This research study focuses on the corrosion properties of both samples (Titanium and Stainless steel) in different corrosive environments such as NaCl, H2SO4 and NaF, and investigates the microstructure before and after corrosive environments. And then, measuring the surface roughness with and without corrosive environments. Finally, XRD for both titanium and stainless steel samples are tested.
