Effects of Surface Roughness on the Adhesion and Corrosion Properties of Organic Coating Applied on One Surface of One Sample Set of Mild Steel

This report basically discusses the research done and basic understanding of the chosen
topic, which is the Effects of Surface Roughness on the Adhesion and Corrosion
Properties of Organic Coating Applied on One Surface of One Sample Set of Mild
Steel. One of the effected areas after performing surface preparation on any metal
surface is the surface roughness. The samples for this study are mild steel. Three
samples with different surface roughness were prepared. ASTM B 117-90 Salt Spray
(Fog) test is carried out in order to study the corrosion behavior and performance in
accelerated environment. The adhesion behavior was determined by performing scratch
test on the coated surface after underwent the accelerated corrosive environment while
the corrosion performance was determined by visual inspection. In this study, oil
modified alkyd-based enamel coating is selected as the test sample.
