Model development of Coating Material for Low Carbon Steels using Multi Criteria Decision Making Techniques

Fluid handling equipment such as propellers, impellers, pumps, and pumps in warships and submarines all suffer from flowbased erosion-corrosion concerns. While numerous coating materials are available to counteract erosion corrosion damage in the aforesaid components, iron-based amorphous coatings are thought to be more effective. This paper concentrates on the selection of the coating material for AISI 304L SS. In this investigation, WC-10Co-4Cr coating was developed on stainless steel substrate using MCDM techniques. Fuzzy analytic hierarchy process (FAHP) is the technique applied to calculate the weights of Criteria and Combinative DistanceBased Assessment Method (CODAS) is utilised for ranking the Alternatives.
