Effect of Preliminary Nitric Chemical Treatment on Corrosion Behavior of 316 Stainless Steel in Chloride Solution Contain Glucose
Abstract
The aim of this study is to analyze the impact of a preliminary nitric acid chemical treatment on the corrosion of 316 stainless steel particularly used in implant applications, in a 0.9% chloride solution containing glucose. The steel 316 study has a variety of distinct phases and inclusions. Chemical nitric acid treatment for three days at 22°C changes the open circuit potential in the chloride solution, containing one, two or four grams per liter of glucose, after one hour and eight days of immersion at 37°C. The results show that the open circuit potential is higher when the solution contains two or four grams of glucose per liter after one hour and eight days of immersion at 37°C. In contrast, the corrosion potential of chemically treated samples increases when immersed in a chloride solution containing two, or four grams of glucose per liter, while their resistance to polarization decreases after one hour of immersion. However, after eight days of immersion in sodium chloride solution, chemically treated samples have lower corrosion potentials for different glucose concentrations compared to untreated samples, and the polarization resistance decreases only for those immersed in chloride solutions containing two or four grams of glucose per liter. In addition, untreated samples show an increase in their polarization resistance and corrosion potential with the increase in glucose concentration after one week of immersion. A significant morphological difference in corrosion is observed between chemically treated and untreated samples when immersed in a chloride solution. In addition, the rate of pitting formation decreases for untreated samples after one week of corrosion; this may be explained by the passivation of untreated 316 steel after one week of free corrosion in the sodium chloride solution.
