METHOD OF REALIZATION ANTICORROSION COAT ON THE SHIELD WARM OF FURNACE CHAMBER

摘要

The invention provides using three-phase process for applying two-layer anticorrosion coating forming the base for a cooling shield in a boiler firebox, where in the first phase the base has a purity level Sa 3 and a surface roughness Rz 35-100 micron and in the second phase Al powder is sprayed on in argon, and in a third phase the Al top layer is heated to obtain AlO.
