Abstract

In the present investigation, the NiCrMoFeCoAl-30%SiO2 composite coating was sprayed on T22 bare steel with the HVOF technique. HVOFtechniqueallows the production of dense, excellently structured coatings with smoother surfaces and enhanced mechanical properties of the boiler materials. The produced coatings are characterized for their microstructure, and corrosion resistance by high-temperature corrosion.The specimen microstructure has been characterized by SEM/EDS and XRD methods. The coating thickness, porosity, microhardness, and coating density have been assessed.
