2/1/2021 · This experimental study is an attempt to investigate the comparative hot corrosion performance of different ceramics coatings on boiler tube steel. The different coatings have been deposited by high velocity oxy fuel technique by mixing 10, 20 and 35 wt% of Cr3C2 in NiCr. The coated samples were tested in simulated boiler environment of molten salt at 800 °C temperature. The …

The Characterization of Twin-Wire Arc-Sprayed FeCrBSi Coating and the Application in Sewage Sludge Boilers…

19/9/2014 · Incineration in boilers is an environment-friendly treatment for industrial and civil sewage sludge. However, due to the aggressive nature of the sludge, the boiler fireside-surface is subjected to severe wear, erosive, and high temperature corrosion problems during incineration. In this study, we developed an economical FeCrBSi wire material with iron weight content as high as 80%. The
