This research work aims at investigating the performance of the gas tungsten arc welded dissimilar AISI 304 and AISI 310S when subjected to cyclic hot corrosion in air oxidation and in the molten salt environment of K2SO4 + 60% NaCl environment at 600°C. The weldments are characterized for its mechanical and metallurgical properties. Tensile strength of the weldment is found to be 529 Mpa. Further the hot corrosion studies are performed on the various zones of the weldment and the corrosion products are characterized by the combined techniques of optical microscopy, XRD and SEM/EDAX analysis.

The present study aims to evaluate the hot corrosion behaviour of the Ni-based alloy Superni- 75 in the molten salt environment of Na2SO-60%V2O5 at 900°C under cyclic conditions. The thermogravimetric technique was used to establish the kinetics of corrosion. X-ray diffraction, scanning electron microscopy/energy-dispersive analysis and electron probe microanalysis techniques were used to analyse the corrosion products. Superni-75 has successfully provided the hot corrosion resistance to the given molten salt environment. The hot corrosion resistance of the Superni-75 has been attributed to the formation of uniform, homogeneous and adherent thick layer of the scale consisting mainly of oxides of nickel and chromium, and refractory Ni(VO3)2. These oxides and refractory nickel vanadates have blocked the penetration of oxygen and other corrosive species to the substrate.

Marine Applications

An attempt was made to study the hot corrosion behavior on gas tungeten arc welded Austenitic stainless steel AISI 304 and Nickel-copper alloy Monel 400. These materials are widely used in power plant, petro-chemical and marine applications where the weldments are usually subjected to aggressive corrosion environment. GTA welding was carried out using ENiCu-7 and E308L filler wires. Various regions of the weldment of AISI 304, Monel 400 were exposed to the air oxidation as well as in the molten salt environment consist of K2SO4 + NaCl (60%) at 700°C. Mechanical properties of the weldments were also studied. The corrosion products of the weldments were analyzed using SEM/EDAX, XRD analysis.
