摘要: AbstractThe variation with time of the open circuit potentials six molybdenum containing stainless steels was measured in Arabian Gulf water under conditions simulating operation multistage flash evaporation distillers. The effects temperature range 22–70°C and sea concentrated by cold to between 100 150% were examined detail. With all steels, plots potential as a function logarithm immersion consisted two straight line segments: first, characterised lower slope, attributed formation very thin, barrier type oxide layer, whereas second related longer times immersion, indicating thicker film. mean rates thickening both forms (δ¯1 δ¯2) computed according transient theory. Depending on steel, δ¯2/δ¯1 varied 4·6 11·0 below 40°0C 1·1 1·6 at 70°C. Curves representing δ¯1 δ¯2 exhibited ma...
