Abstract
The present invention provides a corrosion-resistant structure for a high-temperature water system comprising: a structural material; and a corrosion-resistant filmformed from a substance containing at least one of La and Y deposited on a surface in a side that comes in contact with a cooling water, of the structural materialwhich constitutes the high-temperature water system that passes a cooling waterof high temperature therein. Due to above construction, there can be provided the corrosion-resistant structure and a corrosion-preventing method capable of operating a plant without conducting a water chemistry control of cooling water by injecting chemicals.
