Epoxy/alumina composite coating on welded steel 316L with excellent wear and anticorrosion properties

Abstract The main purpose of this study is to elaborate anticorrosive coatings for the welded steel 316L, since this later is widely used in industrial field. Hence, within this work we have studied the electrochemical behaviour of different zones of the welded steel 316 in 1 M HCl media. The macrog...
