Well, George, as 007 says, phosphoric acid does not convert rust back to iron. It converts it to iron phosphate, which is a stable, corrosion resistant substance that makes an excellent base for paint. If you remove the black phosphate coating, then you're back to steel. Phosphate coatings are used on military hardware, particularly firearms, due to their corrosion resistance and non-reflective appearance.
