ANTICORROSIVE COATING FILM, HEAT TRANSFER PIPE AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an anticorrosive coating film capable of not only preventing corrosion or exfoliation caused by sour gas generated inside a coal-fired power generation boiler but also suppressing arrival of the sour gas to a heat transfer pipe; and to provide a heat transfer pipe having the same formed thereon.SOLUTION: An anticorrosive coating film having a ground layer comprising a M-Cr-Al-Y-based alloy (M is at least one kind of Ni, Co and Fe), and a surface layer containing stabilized ZrOand inorganic glass having a slow cooling point of 600-800°C, is formed on a substrate.
