Corrosion behavior of AISI321 stainless steel in an ethylene glycol-water solution

Porous metallic alloys are reported as the prospective biomaterials for restorative medicine due to their unmatched features guaranteeing fixation of prosthesis. Numbers of research are focused on functional properties of porous materials. Especially corrosion behavior seems to differ from the analogue bulk materials. The aim of presented work was to study corrosion resistance of sintered porous implant steel 316L. Samples with porosity in range of 26-40% were fabricated by means of the PM method. Corrosion tests were carried by using an automatic polarization unit Atlas-Solich98 in 0.9% NaCl water solution. The experiments conducted confirm that porous 316 stainless steel possesses a distinct passivation range. The obtained results showed the effect of pore morphology on corrosion resistance of sinters.

Stainless Steel 316

Stainless steel is commonly applied for food processing equipment because of its stability in acid-base conditions. However, corrosion and metal release from the steel can occur in some situations lead to food contamination and decrease the component reliability as well. The objective of the present work is to study the corrosion behavior of austenitic stainless steel 316 L in a water solution containing 9 wt.% NaCl mixed with different concentrations of citric acid. Immersion test and polarization measurements were conducted to quantify the corrosion rate and polarization behaviors of the samples. The result shows that the shape of polarization curves and the corrosion rate are pH dependence. An increased citric acid concentration until the pH value of 4 will enhance the passive film development, but the further increase in acidity aggravates the corrosion attack.
