  • High coating weight iron phosphating, compositions therefor, and use of the coating formed as a lubricant carrier
    Patent number: 5891268
    Abstract: Iron phosphate conversion coatings that are well adapted to serve as carriers for metal cold working lubricants, particularly such lubricants that contain polyoxyethylene adducts of long chain primary alcohols as a major lubricating component, can be formed on ferriferous surfaces within practical times such as 5 to 10 minutes by contact with an aqueous solution of almost neutralized phosphoric acid that has sufficient Free Acid and/or Total Acid content to form a heavier phosphate conversion coating than do conventional iron phosphating compositions. The phosphate conversion coating forming aqueous liquid composition advantageously also contains an accelerator component such as chlorate or hydroxylamine.
