Corrosive Wear Behaviour of Plasma Sprayed Inconel 718 and Titania Coatings on Low Carbon Steel In Marine Environment

Abstract

Low carbon steel is most widely used in marine and agricultural application due its wide availability and low cost. One of the major limitations of using low carbon steel is its susceptibility to corrosion resulting in loss of material and huge replacement costs. In order to overcome this limitation, one of the methods is applying surface coatings thereby enhancing its corrosion resistance in sea water environment. Plasma spray technology has become very prominent in the field of application of ceramic coatings mainly to protect material surfaces from corrosion and wear. In this direction an attempt has been made to develop coatings composed of TiO2 and Inconel 718 on low carbon steel substrates and subject them to corrosion test under simulated conditions.
