How Is the Corrosion Resistance of TZM Molybdenum Alloy?

TZM molybdenum alloy has certain corrosion resistance. Compared with pure molybdenum, TZM molybdenum alloy has better corrosion resistance and can withstand certain acid, alkali and salt corrosion. Specifically, TZM molybdenum alloy has good corrosion resistance to nitric acid and sulfuric acid at high temperature, but has poor corrosion resistance to strong acids such as hydrofluoric acid, hydrochloric acid and hydrobromic acid, and is prone to corrosion. In an oxidizing atmosphere, a dense oxide film will form on the surface of the TZM molybdenum alloy, which can improve its corrosion resistance. In general, the corrosion resistance of TZM molybdenum alloy is closely related to its chemical composition, preparation process, surface treatment and other factors.
