Surface preparation is the pre-treatment step before any application of paint or coating, for better resistance toward the corrosion and chemical reaction between metal and chemicals and long life of job. Surface preparation helps to remove contaminant like rust, dust, oil, moisture etc. Surface preparation of metal is one of the key factors in order to ensure consequent properties of coating. This is mainly done to produce effective adhesion between coating and substrate. Interfacial adhesion can be done through two general mechanisms electrostatic bond and mechanical inter locking. electrostatic bond between the coating and metal substrate can be improved by removing any significant oxide layer and impurities. Surface roughness enhance the mechanical inter locking of coating within the surface irregularities. As a part of surface preparation sand blasting process is performed on the surface of M.S.G.L pressure vessel. Nozzle type, blasting pressure, stand of distance, Blasting angle, and Size of the abrasive are the parameter which affect the blasting time and surface roughness, Blasting process consume high time and high cost. By changing above five parameter we have perform number of experiment and get conclusion that for a specific rang of roughness we need specific process parameter, so we get given roughness in minimum time.
