Metal Salts As Flux in Hot Corrosion
Hot corrosion can affect gas turbines operating in high salt environments (e.g., near the ocean). Salts, including chlorides and sulfates, are ingested by the turbines and deposited in the hot sections of the engine; other elements present in fuels also form salts, e.g. vanadates. The heat from the engine melts these salts which then can flux the passivating oxide layers on the metal components of the engine, allowing corrosion to occur at an accelerated rate.

Famous quotes containing the words metal, flux and/or hot:
“We are supposed to be the children of Seth; but Seth is too much of an effete nonentity to deserve ancestral regard. No, we are the sons of Cain, and with violence can be associated the attacks on sound, stone, wood and metal that produced civilisation.”
—Anthony Burgess (b. 1917)
“Sense is a line, the mind is a circle. Sense is like a line which is the flux of a point running out from itself, but intellect like a circle that keeps within itself.”
—Ralph J. Cudworth (1617–1688)
“There is little for the great part of the history of the world except the bitter tears of pity and the hot tears of wrath.”
