Abstract: A PROCESS FOR APPLYING A PROTECTIVE COATING ON ALUMINUM, ZINC AND IRON UNDER SUBSTANTIALLY INDENTICAL OPERATING CONDITIONS WHICH CONSISTS ESSENTIALY OF APPLYING TO THE METAL SURFACES OF ALUMINUM, ZINC AND IRON OF A COMPLEX FLUORIDE COATING SOLUTION FREE FORM CHROMIC ACID, PHOSPHORIC ACID AND OXALIC ACID HAVING A CONCENTRATION OF FROM 0.1 TO 15 GM. PER LITER, BASED ON THE METAL CONTENT, OF COMPLEX FLUORIDES OF METALS SELECTED FROMTHE GROUP CONSISTING OF BORON, TITANIUM, ZIRCONIUM AND IRON, FROM 0.1 TO 10 GM. PER LITER OF FREE FLUOREDE IONS AND FROM 0.5 TO 30 GM. PER LITER, CALCULATED AS SODIUM M-NITROBENZENE SULFONATE, OF AN OXIDIZING AGENT, AT A PH OF FROM 3.0 TO 6.8 FOR A TIME SUFFICIENT TO FORM A COATING. THE APPLIED COATINGS CNA BE POST-PASSIVATED WITH SOLUTIONS CONTAINING CHROMIC OR PHOSPHOORIC ACIDS.

Abstract: A PROCESS FOR THE APPLICATION OF CONTINUOUS PHOSPHATE COATINGS ON IRON, STELL AND ZINC SURFACES. THE LAYERS ARE OF A THICKNESS OF ONE MICRON OR LESS AND ARE OF PARTICULAR HARDNESS. THESE COATINGS ARE PRODUCED BY SPRAYING ON THE METAL SURFACES AN AQUEOUS SOLUTION CONTAINING, ASIDE FROM ZINC-, PHOSPHATE-AND NITRATE IONS, NO2-INS, WATER-SOLUBLE GLYCEROPHOSPHATE AND NONIONIC DETERGENTS, ALL IN PREDETERMINED AMOUNTS IN VERY NARROW LIMITS. FOR THE COATING OF ZINC SURFACES, AN ADDITION OF A FLUORO-COMPLEX IS OPPORTUNE. THE RATIO OF TOTAL ACID TO FREE ACID IS TO BE HELD AT 8 TO 12. IN THE PROCESS ACCORDING TO THE INVENTION, A PRETREATMENT, E.G., DEGREASING, NOT ONLY IS NOT REQUIRED BUT ACTUALLY MAY BE DELETERIOUS. PHOSPHATE LAYERS OF 0.5 MICRON READILY CANA BE ATTAINED.
