Corrosion and Heat Treatment of Paint Coating Containing Battery Cathode Waste Material-Epoxy Resin in 3.5 wt% Sodium Chloride Solution

摘要

This study investigates the effect of heat treatment at 25, 100, 350, and 500 C on the durability ofmild steel samples coated with an epoxy paint coating system with various weight percentages ofcathode waste material (CWM) in 3.5 wt% sodium chloride (NaCl). The epoxy paint coating systemsincorporated with 0 and 10 wt% of CWM and exposed at 100 C possessed reasonable thermalstability and barrier protection after the corrosion test. The results indicated that these coatings canprotect the substrate from severe corrosion for 720 h of electrolyte immersion. Moreover, the highepoxy cross-linking and excellent filler particle arrangement improved paint coating adhesion on themild steel surface.
