Abstract
The corrosion behavior of riveted dissimilar metals TC4-316L in simulated marine atmo-spheric conditions was investigated by means of mass loss methods, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and confocal laser scanning microscopy. While the corrosion kinetics, rust composition, and corrosion morphology are mainly concerned. The results indicate 316L stainless steel is corroded when riveted parts TC4-316L were immersed in 3.5%NaCl solution peri-odically for 1200 h, but TC4 Ti-alloy has no obvious corrosion. The corrosion products of 316L stainless steel composed of FeOOH, Fe3O4 and Fe2O3, while the oxide scale formed on the surface of TC4 Ti-alloy is mainly TiO2 and Ti2O3. Compared with the corrosion behavior of the bare 316L stainless steel, the 316L stainless steel with riveted TC4 Ti-alloy was suffered from accelerated corrosion due to the combined effect of galvanic corrosion and crevice corrosion.
