摘要： A method of producing an automotive vehicle bumper from an extruded blank of a heat treatable, age hardenable aluminum alloy. The method comprises heating the blank to a solution heat treating temperature for the alloy, working the blank while hot to a preliminary contour, quenching the hot formed blank to a temperature at which the temper of the alloy is unstable, cold working the blank before any appreciable natural age hardening occurs and to a bumper contour in which the blank is dimensionally stable, and ageing the formed and shaped blank. The blank may be subjected to further finishing operations including trimming and hole punching prior to ageing, and buffing, chemically brightening and anodizing the aged blank to enhance the appearance of the outer surface of the final bumper product.

摘要： PIGMENTED SILICEOUS COATINGS HAVING GOOD ADHESION, HARDNESS AND SMOOTHNESS ARE PRODUCED ON THE SURFACE OF AN ALUMINOUS METAL BY IMMERISING THE METAL AS ANODE IN AN AQUEOUS BATH OF AN ALKALI METAL SILICATE CONTAINING AN INSOLUBLE PIGMENT, AND PASSING FULL-WAVE RECTIFIED ALTERNATING CURRENT THROUGH SAID BATH AT A VOLTAGE SUFFICIENT TO CAUSE DISSOCIATION OF THE BATH CONSTITUENTS BY MULTIPLE SPARK DISCHARGING AT THE ANODE SURFACE. THE BATH ALSO CONTAINS AN ALKALI CHROMATE, MOLYBDATE OR TUNGSTATE, AND AN ALKALI CARBONATE, PHOSPHATE OR BORATE. THE COLORED COATING THUS OBTAINED IS DECORATIVE AND USEFUL ON BUILDING TRIM, ALUMINUM SHINGLES AND SIDING, AND THE LIKE.
