Resumo
Albumin is the most abundant protein found in human serum and sinovial fluids. Investigations on its effects on the corrosion resistance of metallic biomaterials have led to controversial conclusions. The BSA (bovine serum albumin) concentration used in most of the studies is below the usual concentration found in the human physiological fluids. This is possibly the reason for the lack of agreement on the conclusions reported in literature. The aim of this study is to evaluate the effect of albumin in concentration on the susceptibility to corrosion of the ASTM F139 austenitic stainless steel (SS) used in fabrication of orthopedic implants, specifically on the areas marked by a Nd: YAG laser. The electrolyte used was a phosphate buffer solution (PBS) and the effect of albumin was investigated by adding 10 g/L into the electrolyte and comparing the corrosion resistance in the two environments, with and without albumin, by electrochemical methods. The Mott-Schottky approach was used to evaluate the electronic properties of ASTM F139 SS oxide layer marked by laser beam. The results showed a strong effect of the albumin on the electronic properties of the passive film and on the resistance to localized corrosion. The albumin changes the flat band potential position, increasing the oxide layer doping densities. The laser marked surface showed lower corrosion resistance in the electrolyte with albumin, when compared to the tests performed with pure PBS.
