Abstract: Provided herein is a process for the pretreatment of workpieces having a surface of aluminum or aluminum alloys for noncutting forming and/or joining by welding or adhesive bonding to similarly pretreated, precoated workpieces, or to precoated parts. The parts are composed of steel, galvanized steel, and/or alloy-galvanized steel. Further provided herein is a subsequent permanent corrosion-protecting treatment by phosphating, by means of a chromium-free conversion treatment, by application of primer, or by surface coating, wherein the workpieces are a) pickled by means of an aqueous, acidic solution comprising mineral acid by dipping or spraying, b) rinsed with water, and c) brought into contact with an aqueous, acidic, chromium-free solution comprising Zr as complex fluoride and Mo as molybdate by application by dipping or spraying. After subsequent drying, a layer weight from 2 to 15 mg/m2 of Zr and Mo is formed.

Abstract: A method of both coating a substrate with aluminum oxide and infusing the substrate with elemental aluminum is disclosed. In one example, the method includes providing a metal powder/polymer binder slurry, the slurry having a solvent, an organic binder, metal granules and a seed element, wherein the metal granules include Al; dispersing the slurry upon a Cr-containing surface; after dispersing the slurry, exposing the slurry to air and maintaining the temperature of the slurry and substrate below 110° C. to remove at least a portion of the solvent from the slurry; and, in a combined step, both exposing the binder, metal granules and substrate to air and heating the remaining slurry and substrate at a temperature less than or equal to 1000° C. to both diffuse at least a portion of the metal of the metal granules into the substrate and coat the substrate with aluminum oxide.

Abstract: The invention relates to a method for creating a diffused thin film surface treatments on one or more interior surfaces of closed or partially closed fluid transport or processing systems providing improved surface prophylaxis against fouling. The method involves contacting the interior surfaces to be treated with a metal compound composition, and converting the metal compound composition to metal oxide for example by heating the surfaces to the desired temperature after all or a part of the system has been assembled. Embodiments of the present invention can be performed in situ on existing fluid processing or transport systems, which minimizes the disruption to the surface treatment created by welds, joints, flanges, and damage caused by or during the system assembly process.

Abstract: A method for producing an organic microdisk structure 40, which is characterized by comprising: a cladding layer formation step 1 wherein a cladding layer 12 is formed by printing a first ink 11 that contains a fluorine-containing hyperbranched polymer on a substrate 10 by an inkjet method; a core layer formation step 2 wherein a core layer 22 is formed by printing a second ink 21 that contains a laser dye and a triazine-based hyperbranched polymer containing no fluorine on the cladding layer 12 by an inkjet method; and an etching step 3 wherein the cladding layer 12 is etched using a solvent 31 that dissolves only the fluorine-containing hyperbranched polymer. Consequently, an unconventional novel method for producing an organic microdisk structure with use of an inkjet method is able to be provided.

Abstract: This surface treatment method comprises a rustproofing step, a rinsing step, and a cleaning step. In the rustproofing step, a rustproofing liquid containing orthophosphoric acid and an organic acid is used to perform a rustproofing treatment on the surface of a steel material. In the rinsing step, a treatment liquid containing an oxo acid salt of a transition metal is used to perform a rinsing treatment on the surface of the steel material. In the cleaning step, the surface of the steel material that has undergone the rinsing step is subjected to a cleaning treatment.

Abstract: The present invention pertains to a method for producing a black-plated steel sheet capable of being blackened in a short amount of time, and exhibiting an excellent ability to maintain a black appearance after processing. As an original sheet, the sheet used is a Zn-plating steel sheet which contains molten Al and Mg and has a Zn-plating layer containing molten Al and Mg, containing Al in the amount of 1.0-22.0 mass %, inclusive, and containing Mg in the amount of 1.5-10.0 mass %, inclusive. The plating layer is blackened by causing the molten-plating steel sheet to contact water vapor inside a tightly sealed container. When doing so, the concentration of oxygen inside the tightly sealed container is 13% or less.

Abstract: An iron-containing metal surface, such as a brushed stainless steel, comprises a heat-set layer of a metal phosphate reaction product formed between a surface metal and phosphate precursor wherein the reaction product layer has an average thickness less than 2 micrometers. A metal surface, that resists retention of environmental stains or marks as well as resisting tarnish at elevated temperatures, is formed by forming a reaction product with the metal surface by heat setting a surface liquid layer containing a phosphate precursor such as a phosphate ester-containing solution or phosphoric acid solution, and optionally containing a phospho alumina precursor, onto the metal surface. An article coated in accordance with this invention is similar in appearance to a similar article without such a coating for maintaining original aesthetic properties.
