In Ni-Cr-Fe-Mo (W) alloys, chromium is the key element that inhibits localized corrosion initiation, while Mo enhances film stability and impedes the …
Nickel Chrome Alloys
Alloys that have undergone this type of attack have wart-like formations on their surface. The preferential formation of chromium sulfides shows that alloys with higher chromium levels are more resilient to this form of attack. Nickel/chromium alloys with over 30% chromium have a two-phase structure including γ-nickel and α-chromium.
Chromium Compound
Chromium compounds are colored as chroma means color in Greek and their oxidation state varies from chromium (II) to chromium (VI) (Jacobs and Testa, 2005).Exposure to chromium can happen through skin contact, breathing, eating or drinking substances containing chromium. Cr (III) is most stable and occurs in the form of ores namely …
