CORROSION BARRIERS FOR HEAT EXCHANGERS
20210025662 · 2021-01-28 ·

A method of applying a heat exchanger coating system includes forming a conversion coated substrate by applying a conversion coat onto a substrate to provide corrosion resistance to the substrate and encapsulating the conversion coated substrate with a pinhole-free, uniform, atomic layer deposited, corrosion resistant coating.
