Development of coating material for low carbon steels using MCDM

Abstract

Fluid handling equipment like propellers, impellers, pumps, and pumps in warships and submarines are all vulnerable to flow-based erosion and corrosion. 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 selected on stainless steel substrate using MCDM techniques. Fuzzy analytic hierarchy process (FAHP) is the technique applied to calculate the weights of criteria and combinative distance-based assessment method (CODAS) is utilised for ranking the alternatives.
