摘要: Vanadium additions increase the pitting potential of 18% chromium ferritic stainless steel. Artificial-pit measurements showed that this is not related to any change in dissolution kinetics pit anolyte, contrast with effect molybdenum which lowers rate strongly. A decrease nucleation metastably growing pits found for vanadium-alloyed steels, but smaller than alloying. The salt film artificial steels was dissolve more slowly molybdenum-alloyed steels; slower expected contribute resistance steels.
