Abstract: Liquid transfer rolls such as printing rolls are made by imposing a hard ceramic coating on an incipient liquid transfer roll in an electrolytic bath subjected to a modified shaped wave alternating current, which causes dielectric breakdown and the formation of a hard ceramic coating on the roll. The roll is laser engraved to form liquid carrying reservoirs or cells on the surface of the roll, either before or after the ceramic coating is built on the roll.

Abstract: An aluminum alloy article is anodized in an aqueous solution of phosphoric acid. Oxide forms on the surfaces of the article and dissolves as it forms to displace contaminants and deoxidize the surfaces. The anodizing etch rate is from about 0.0002 to about 0.0005 inch/surface/hour. Residual oxide on the surfaces is a maximum of about 3000 Angstroms. The article may be left in the solution following anodizing to dissolve a portion of the residual oxide. Preferred anodizing parameters include 15 to 25% by weight phosphoric acid, 75.degree. to 95.degree. F., and 4 to 10 volts. Usual anodizing times are from 5 to 10 minutes. Following deoxidation, the article is ready for subsequent processing, such as anodizing to provide a controlled thickness porous oxide coating followed by adhesive bonding.

Abstract: A process for the electrolytic coloring of aluminum or aluminum alloys consisting of subjecting the previously anodized piece to two electrolytic treatments in a coloring solution (solution of soluble metal salts). The first consists of an alternating current treatment with an elevated positive polarization, to cause a modification in the pores of the anodic layer. After this electrolytic treatment and in the same bath, the sample is colored by applying thereto an alternating current. The electrolytic treatment prior to coloring permits colors differing from those produced in conventional coloring to be obtained.

Abstract: A process is disclosed for the production of bases for offset printing plates in the form of sheets, foils or webs made of roughened aluminum or one of its alloys, which is carried out in an anodic oxidation stage, i.e. in an aqueous electrolyte which contains phosphorus-containing anions. In the procedure, an electrolyte containing dissolved phosphoroxo anions, with the exception of aqueous H.sub.3 PO.sub.4, is employed, and the treatment is carried out for a period of about 1 to 90 seconds, at a voltage between about 10 and 100 volts and at a temperature of about 10.degree. to 80.degree. C. The electrolyte is, in particular, a salt of an oxyacid of phosphorus, such as Na.sub.3 PO.sub.4 or K.sub.3 PO.sub.4. Hydrophilization of the base can be carried out additionally after the anodic oxidation. Also disclosed is a base material produced according to the process and an offset printing plate which includes the base material.

Abstract: Anodizing of aluminum or aluminum alloys at an exceptionally high film forming rate is conducted by the employment of a current density greater than 1.5 A/dm.sup.2 and a concentration of sulfuric acid of from 20% to 30% by weight in an electrolyte solution bath, and by the use of a racking device and cooling device which is designed for said severe conditions of current density and sulfuric acid concentration. A careful selection and regulation of the anodizing temperature enables the option of forming a soft or hard oxide film of greater thickness than achieved heretofore. Bath temperatures of around 30.degree. C. permit the formation of a soft oxide film, while bath temperatures of around 5.degree. C. permit the formation of a hard oxide film.

Abstract: Environmentally stable bond joints of aluminum metal and aluminum alloys in adhesively joined structures are formed by utilizing a prebonding anodization of the aluminum surfaces in a phosphoric acid electrolyte containing from about 1.5 to about 50% H.sub.3 PO.sub.4 at 1 to 50 volts for a period of 5 to 60 minutes using a bath temperature of 50.degree. to 100.degree. F. The anodized surface is then washed free of electrolyte, dried and coated with an adhesive resin. The aluminum metal segments are then arranged in a composite arrangement and bonded together under pressure and heat to cure the adhesive resin. The resulting structure is resistant to failure of the bond joints on exposure to moist atmospheric conditions. The surface preparation provides a hydration resistant aluminum oxide surface which minimizes adhesive-aluminum separation under aqueous exposure. Alloys containing copper and other alloying constituents may be successfully anodized and bonded by this process.
