摘要: Abstract Air receivers in railway coaches usually come under severe degradation due to exposure external atmosphere and corresponding climatic changes. IS 2062 Steel is used for this application. Frequent cleaning replacement become part of the process. Polymer based coating can save material from corrosion subsequent wear. In work poly urea was carried out on an steel. The properties were studied using potentiodynamic polarization test ASTM standard 3.5%NaCl solution. resistance coated compared with base material. depth samples evaluate enhancement IS206. enhances codal life these by manifold.
