摘要： Disclosed are aluminum alloy products and methods of making and processing such products. Thus, disclosed are aluminum alloy products exhibiting controllable surface properties, including excellent bond durability, low contact resistance, and corrosion resistance. Aluminum alloy products described herein include a migrant element, a subsurface portion having a concentration of the migrant element, and a bulk portion having a concentration of the migrant element. The aluminum alloy product comprises an enrichment ratio of 4.0 or less, wherein the enrichment ratio is a ratio of the migrant element concentration in the subsurface portion to the concentration in the bulk portion. Additionally, the aluminum alloy products surface and/or subsurface can contain phosphorus (e.g., elemental phosphorus or oxidized phosphorus). The phosphorus containing surface provides reduced electronic stress on an electrode tip of a resistance spot welding apparatus, and an extended service lifetime (e.g., weld cycles to failure) of the electrode tip.

摘要： Described are methods of treating surfaces of metal alloy substrates and associated metal alloy products. The methods may include providing an aluminum alloy product having a bulk and a surface and scanning abeam of high energy across the surface. The method may further include applying a liquid layer onto the surface prior to scanning a beam of high energy. The beam of high energy may interact with the surface and/or the liquid layer to form a treated surface. The beam of high energy may interact with the surface and/or the liquid layer to physically modify the at least a portion of the aluminum alloy product to form a treated sub-surface layer.

摘要： Described herein is a continuous coil pretreatment process used to treat the surface of an aluminum alloy sheet or coil for subsequent deposition of an acidic organophosphorus compound. The process can include applying a cleaner to a surface of an aluminum sheet or a coil; etching the surface of the aluminum sheet or the coil with an acidic solution; rinsing the surface of the aluminum sheet or the coil with deionized water; applying to the surface of the aluminum sheet or the coil a solution of an acidic organophosphorus compound; rinsing the surface of the aluminum sheet or the coil with deionized water; and drying the surface of the aluminum sheet or the coil.

摘要： Described are techniques for treating metals by exposing the metals to reactive solutions to reduce a temperature of the metal and to modify a surface of the metal through chemical reaction, such as by removing material or adding material. The disclosed techniques may advantageously increase the rate at which the temperature of the metal may be reduced as compared to conventional cooling techniques involving pure water, increase metal manufacturing rates, and reduce overall complexity of a metal manufacturing process. The disclosed techniques may also advantageously expand the range of available surface treatments, allow for faster surface treatment processes, and reduce or eliminate the use of hazardous chemicals during a surface treatment process. Such advantages may arise by employing chemical processing that takes place or takes place more efficiently at elevated temperatures.

摘要： A non-contact heating apparatus uses a series of rotating magnets to heat, levitate, and/or move metal articles therethrough. A first series of rotating magnets heats the metal article to a desired temperature. A second series of rotating magnets levitates the metal article within the heating apparatus and maintains desired tension in the metal article, including urging the metal article through the heating apparatus. The heating apparatus can extend sufficiently far to soak the metal article at the desired temperature for a desired duration. The rotating magnets can be positioned outside of an electrically non-conductive, heat resistant chamber filled with an inert or mildly reactive gas, through which the metal article passes in the heating apparatus.
