| Abstract: | The corrosion cause of "four kinds of piping" in power plant boiler is briefly analyzed, and the developing situation of anti-corrosion of boiler tubes is presented. The hot spraying technology and its application in hot-corrosion protection for boiler tubes and high CrNi alloy's excellent corrosion resistance is also provided in detail. It is pointed out that arcspray, especially high velocity arc-spray has an extensive application in boiler tubes. |
