Rouging is a type of corrosion that occurs in certain closed water systems made of stainless steel, such as purified water systems.
There are various theories about the causes of rouging. The most likely explanation is that the passive layer cannot reform if it wears away in oxygen-depleted water. In three different case studies involving three industrial water systems, it has been demonstrated that rouging can be mitigated through electropolishing.
