| Abstract: | This paper describes the corrosion behavior of heating pipe in hydrazine hydrate evaporator, and shows that the main mechanism is cavitation corrosion. The chemical corrosion by the hydrazine hydrate solution enhances cavitation corrosion. The main measure to prevent the corrosion of the heating pipe is suggested. |
