Abstract:
A method of disposing a corrosion resistant system to a substrate may comprise applying a plating material to the substrate; forming a chemical conversion coating solution by combining a solvent, at least one corrosion inhibitive cation comprising at least one of zinc, calcium, strontium, magnesium, or aluminum, at least one corrosion inhibitive anion comprising at least one of phosphate, molybdate, or silicate, and a complexing agent; and applying the chemical conversion coating solution to the plating material on the substrate.
