Overview of coatings for a cyclic-temperature environment. Test method, including a heat cycle between 21 to 300 deg-C simulating the dehydrator operation and exposure to salt spray. The performances of the three coatings were evaluated using this method. Factors to be considered for coating selection in the cyclic-temperature environment are discussed.c
This study focuses on a better understanding of significant pitting corrosion on coating surface damaged carbon steels, or low alloy steels, during salt spray testing for automotive applications. Anodic cyclic polarization test was used to evaluate the severity of pitting corrosion, and to estimate the corrosion rate of raw materials.
Encapsulation of Linseed Oil & Tung Oil in urea-formaldehyde shells was performed using in-situ polymerization technique. Thin film self-healing coatings with uniform and quick self-healing ability were achieved with microcapsules at concentration of 3 wt%. Anti-corrosive performance was evaluated using immersion test & electrochemical impedance spectroscopy (EIS).
