Metabolic Albumin and Its Effect on Electrochemical Behavior of Titanium Implant Alloy

Abstract

Human albumin is a protein made by the liver. It is the most abundant circulating protein, accounts for 50-60% of total protein in the blood and plays many roles. The most important are the oncotic and non-nociceptive properties. The albumine is part of the family of globular proteins, the most common of which are the serum albumins. All the proteins of the albumin family are water-soluble, moderately soluble in concentrated salt solutions, and experience heat denaturation. Albumin is commonly found in blood plasma and differs from other blood proteins because it is not glycosylated. Thanks to their unique properties and benefits such as superior biocompatibility and good corrosion resistance, Titanium and Titanium alloys have many uses. Their applications include dental implants and parts for orthodontic surgery; replacement parts for hips, knees, shoulders, spine, elbows and wrist joints; bone fixation devices such as nails, screws and nuts; housing parts for pacemakers and artificial heart valves; surgical instruments and components in high-speed blood centrifuges. In SITU electrochemical measurements are: open circuit potential (OCP), polarization resistance (Rp), potentiodynamic polarization (PD) and cyclic voltammetry polarization (CV) were performed to monitor the corrosion process. The optical images of the tested samples have been observed before and after corrosion experiments using an optical microscope (Optika) in order to understand the nature of corrosion and the damages produced by this process.
