Abstract

The plasma-sprayed NiCr–Cr2O3 and Al2O3–40 % TiO2 powders are deposited as coating on nickel-based superalloy. The electrochemical polarisation studies were carried out with 1.0 M H2SO4 solution as a corrosive medium. The corrosion current density of the coated sample was found to be decreased and exhibits better corrosion resistance than bare metal. The characterisation studies on the exposed sample result reveal that the bare metal has undergone severe intergranular attack and segregation on austenitic phase. The corrosion products formed are in the form of sulphides, and contribution of sulphur was noticed through EDS analysis.
