Method and composition for obtaining diffused aluminum coating layers on metal articles

Claim 1

A PROCESS OF APPLYING A DIFFUSED METALLIC PROTECTIVE COATING TO A METAL ARTICLE WHICH COMPRISES: COATING THE SURFACE OF SAID ARTICLE WITH A MIXTURE INCLUDING SMALL PARTICLES OF A METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM AND ALUMINUM ALLOYS AND A WATER VEHICLE, AND ALUMINUM AND ALIMINUM ALLOYS AND A WATER VEHICLE, AND APPROXIMATELY .27 TO 1.64 PERCENT OF UNREACTED BORAX BY WEIGHT OF SAID WATER TO MAINTAIN FROM 1000 TO 6000 P.P.M. OF BORON OXIDE IN SOLUTION FOR PREVENTING REACTION P.P.M. OF BOROM OXIDE IN SOLUTION FOR PREVENTING REACTION BETWEEN THE WATER AND COATING METAL PARTICLES; AND FIRING SAID COATED ARTICLE AT AN ELEVATED TEMPERATURE THAT CAUSES SAID COATED ARTICLE AT AN ELEVATED TEMPERATURE THAT CAUSES THE COATING METAL TO DEVELOP A DIFFUSED METALLIC PROTECTIVE COATING LAYER ON THE SURFACE OF SAID ARTICLE. FACE FORMED BY THE PROCESS OF APPLYING A MINERAL COATING IN THE PATH OF DISCHARGE THEREOF; A PLATFORM MOUNTED FOR FREE ROTATION IN SAID TANK CONCENTRICALLY THEREOF AND ON ONE SIDE THEREOF, APPLYING A DYE IN THE FORM OF AN AQUEOUS SOLUTION CONTAINING FROM 0.2% TO 0.015625% BY ADAPTED TO SUPPORT AN EGG BASKET WITH ITS SIDES EXPOSED TO THE PATHS OF DISCHARGE OF SAID APERTURES AND ITS TOP WEIGHT OF THE DYE TO THE OPPOSITE SIDE THEREOF, SAID DYE HAVING THE PROPERTY OF INCREASING OPACITY OF THE PAPER BELOW SAID BAFFLE; MEANS FOR INTRODUCING WASHING LIQUID UNDER A POSITIVE PRESSURE TO SAID CONDUIT MEANS. YET HAVING A MINIMUM ADVERSE EFFECT ON BRIGHTNESS AS MEASURED FROM THE COATED SURFACE OF THE PAPER, AND CALENDERING OF THE COATED, FINISHED PAPER TO IMPROVE THE PRINTING QUALITY OF THE COATED SURFACE THEREOF AND WHEREIN THE PAPER IS CHARACTERIZED IN THAT IT IS SUBSTANTIALLY FREE FROM FILLER MATERIALS.
