  • Patent number: 5795661
    Abstract: A method for improving the formability of zinc coated steel sheet, and the product produced therefrom. The steps of the method include applying to the zinc coating an oxalic acid solution in an amount that will form a zinc oxalate film having a coating weight in a range of s about 10 mg/ft.sup.2 to about 100 mg/ft.sup.2. A lubricant is applied to the zinc oxalate film, and the lubricant is adsorbed by the zinc oxalate film to provide a lubricated zinc oxalate film that is bonded to the zinc coating. The method produces an improved zinc coated sheet product having a tightly formed lubricated coating structure resistant to galling in the die steels of a forming press. The improved zinc coated sheet product having a lubricated zinc oxalate film improves formability and reduces the coefficient of friction during the forming operations that shape the zinc coated steel sheet or strip into a finished product shape.

    Abstract: Dielectric sealing of porous anodized aluminum, in which moisture in the pores of the oxide coating formed by hardcoat anodizing is removed, and the porous anodized surface then impregnated with a dielectric wax. Suitable wax sealants include Carnauba and Montan waxes. The anodized member is preliminarily heated to a temperature in the range 120.degree.-180.degree.

This heating process may be continued for the purposes of impregnating the pores with the wax sealant, which is applied as a hot melt. Alternatively, the preliminary dehydration is achieved simply by heating the member to the impregnating temperature, with no separate dehydration stage. Any excess material remaining on the member's surface is removed. The resulting product has excellent resistivity and dielectric properties, and maintains these properties at elevated humidities.

  • Patent number: 4486510
    Abstract: A method of manufacturing a tuner chassis, in which a tuner chassis assembly is entirely dipped in a molten solder bath to effect the plating of the chassis surface with a solder layer, and thereafter the chassis assembly is dipped in an oil bath heated to a temperature higher than the melting temperature of the solder and then raised, whereby the state of solder plating on the chassis surface is improved by making use of the mechanism that oil forms an oil film on the chassis.

  • Patent number: 4228200
    Abstract: A method for controlling the coating of wires, strips or the like, emerging from molten metal baths, involving subjecting the wire to a single stationary, alternating electromagnetic field generated by an electromagnetic device positioned at or below the point of emergence such that the point of emergence is always within the electromagnetic field. The frequency and/or current for generating the field may be adjustable, and the field generated by either parallel or transverse to the wire, strip or the like. The wire, strip or the like may pass through, or adjacent, the electromagnetic device. A neutral or reducing atmosphere may be provided within a chamber situated at the point of emergence and the point of emergence covered with particles inert to the environment. Alternatively the emergence area, may be covered by a confined or unconfined bed of oil charcoal.

  • Patent number: 4165242
    Abstract: A method of treating metal parts to provide durable and rust-inhibiting coatings is described. The application method can be used to treat single parts or bulk barrel processing of parts. The method comprises the steps of(a) phosphating the metal parts with an aqueous metal phosphating solution,(b) electrophoretically depositing a siccative organic coating on the phosphated metal parts, and(c) applying a corrosion inhibiting film of oil as a seal coat.

  • Patent number: 3983305
    Abstract: The invention provides a novel method of increasing the corrosion resistance and improving the organic coating characteristics of cold rolled flat steel. In practicing the method, cold rolled flat steel in the as rolled condition having iron oxide and thermally degradable rolling oil on the surface thereof is heat treated at a tempterature sufficiently elevated to thermally degrade the rolling oil. The surface of the cold rolled steel has a relatively low corrosion resistance and relatively poor organic coating characteristics initially, and the heat treatment is continued until the corrosion resistance and the organic coating characteristics of the resulting heat treated steel are improved. Thereafter the heat treated steel is cooled to a temperature sufficiently low to prevent further thermal degradation of the rolling oil and produce a residual film on the heat treated steel surface which imparts corrosion resistance and improved organic coating characteristics.
