Corrosion Resistance of Inconel 625 CMT-Cladded Layers

The coating was prepared at the boiler manufacturing plant using the cold metal transfer (CMT) method. The Inconel CMT was cladded on the surface of 16Mo3 boiler steel (outer diameter = 60 mm, wall thickness = 6 mm). In turn, the thickness of Inconel CMT cladding was 2–3 mm. The chemical composition of the Inconel 625 is listed in Table 1.
