Phosphate conversion coatings are used on aluminum for extruding, functioning as a lubricant.10 WebOwing to its phosphate-rich characteristics, PA can bind strongly with many metal ions, such as Zn 2+, Mg 2+, Cu 2+, and Fe 3+, via metal chelation. Upon contact with the metal and metal oxide substrates, PA is readily adsorbed on their surfaces to form the phosphate-based conversion coatings.
