Definitions

  • This invention relates to the art of producing a chemically bonded chromate conversion coating on surfaces of aluminum or alloys thereof in which aluminum is the principal or predominant ingredient.
  • the principal object of the invention is to render aluminum surfaces highly resistant to corrosion regardless of whether or not the coated surface is subsequently given a finish of paint, lacquer, enamel, japan or the like.
  • the present invention is based upon the discovery that the corrosion resistance which can be imparted to surfaces of aluminum by treatments of the character just described can be still further enhanced if there be added to the baths which are employed in producing the coat-# ing ions of metal from the class consisting of zirconium, titanium and tin. Moreover, the use of such metal additions to coating baths of the character described makes it possible to operate the baths at considerably lower temperatures than has heretofore been customary. Indeed, with our invention, it is even possible to produce coatings at room temperature or lower. By room temperature is meant average living temperature, which is in the neighborhood of 72 F.
  • the form in which the dissolved zirconium, titanium or tin is introduced into the coating bath appears to make little or no difference so long as the composition of the solution is not otherwise adversely disturbed.
  • these metals should not be introduced along with reducing agents which would cause a loss of hexavalent chromium by the reduction thereof to trivalent chromium.
  • Diammoniumsilicofluoride (NHqJgslFs 14 Chromic acid--- 10 Zirconium nitrate Zr(NO .5H O 12 Water to make 1 liter.
  • mixtures of the metals may be used.
  • the amount of stannic chloride used may be reduced by means of additions of titanium trichloride or of zirconium nitrate or both.
  • the surface to be coated should first be cleaned.
  • the cleaning which forms no part of the present invention, may be carried out by conventional methods. For instance, grease and dirt may be removed by dipping into a mild silicate alkali bath or by the use of an emulsion of a grease solvent.
  • the clean work either wet or dry, may be treated with a solution of the character described, such for example as the solutions of the formulae given above.
  • the treatment may be given by immersing the surface to be coated in the solution, by flowing or spraying the solution on the work or by any other convenient technique in which the solution is allowed to act upon the work.
  • the solution of Formula No. 1 may be heated to approxi mately F. and the clean work immersed in it for approximately 30 seconds to 2 minutes.
  • the article may be rinsed with clean water and dried and afterwards painted, if desired.
  • the rinsing may be done with a dilute solution of Formula No. 1, after which the article may be dried and then painted. Or, if the piece is not to be painted, it may simply be removed from the solution and dried.
  • our invention makes it possible to operate with baths at considerably lower temperatures than has been possible heretofore.
  • prior practice coating baths of silico-fluoride and chromic acid have been used hot,fi. e., at or near the boiling point. With our solutions thisis not necessary, although some slight increase in temperature may be employed if desired because of the greater rapidity of the resulting actioiif Nevertheless, and by way 'of-specific example, Form'ulfNo. 5 as given above will produce excellent corrosion resistant coatings if the cleaned article is immersed in the bath for a period of 1 to 2 minutes at a temperature not exceeding 80 F. Subject to minor variations the formulas of the other examples will yield comparable results as to temperature and time of treatment needed to produce good coatings. This is a marked and very valuable advantage of our invention.
