Conversion Coatings: Phosphate vs. Zirconium

The zirconium chemistry will replace the rinse stage of the iron phosphate process, also making it less expensive to operate and convert; remember, zirconium coatings do not require heat. Also, the existing, larger iron phosphate stage will be converted into a rinse stage, and cleaning of this stage will not be as critical because it will not contain chemistry.

Chemically. zirconium is highly reactive - in air or in aqueous media, it promptly develops an oxide film, which makes it stable with regard to corrosion. The stability can, however, be drastically reduced by fluoride ions, even in trace amounts [12]. Zirconium is stable in both acid and caustic media. At high temperatures it is attacked slowly
