Abstract

Stainless steel exhibits corrosion resistance under ordinary atmospheric conditions; however, corrosion attacks can occur at certain temperatures. Ceramic material coatings are required to improve the corrosion resistance at elevated temperatures. This study aimed to coat stainless steel with Polyaniline/Al2O3/Epoxy and Polyaniline/Al2O3/Al/Epoxy. The research methodology includes sanding specimens with dimensions of 40 mm x 40 mm x 1.5 mm using 60-grit sand paper. The Polyaniline/Al2O3/Epoxy slurry was prepared with an Al2O3 to Polyaniline powder ratio of 3:7. For every 1 gram of Polyaniline/Al2O3 mixture, 15 mL of epoxy was added as the binder. The slurry was applied to the substrate using the wet spraying method, with a spray gun nozzle distance of 100 mm from the substrate and a spraying pressure of 2 bar. The adhesion of the coatings was evaluated using a Hot-Cross-Hatch Adhesion tester. Adhesion tests were conducted on unsanded and sanded substrate specimens. The surface roughness of the unsanded specimen was 0.374 μm, while the sanded specimen showed a surface roughness of 1.521 μm. The hot cross-hatch adhesion tester adhesion test results showed no delamination for the sanded specimens, while the unsanded specimens delaminated by 2.163%.
