    Abstract: The present invention relates to a galvanization process that comprises a residue cleanup step which aims to provide many improvements and facilities to manufacturers and processors of metal wires in general. The process of this invention removes the use of lead of the conventional wire cleaning process for galvanization and incorporates a step with a stearate removing composition which maximizes the galvanization efficiency and reduces lead acquisition and energy costs to heat said lead, and avoids handling of lead and oxide formed on its surface. Thus, the process of this invention makes the environment less insalubrious and reduces the impact of this activity on the environment.

  • Patent number: 8399103
    Abstract: A method of a pre-treatment process for coating notably improves both the surface roughness of a coating layer of a cemented carbide cutting tool and the bonding force of the coating layer to the substrate. According to the method, a sintered surface layer within a range of 0.5-5 ?m, which corresponds to the tungsten carbide particle size of a substrate, is properly removed from the substrate surface of a cemented carbide cutting tool. Thus, a porous sintered surface layer having a non-uniform structure is removed and a substrate surface having high structure density and evenness is provided compared to blasting pre-treatment. In order to obtain a sufficient bonding force between a coating layer and the substrate, the surface ratio of open pores, which exist around tungsten carbide particles appearing by removal of the porous sintered surface, is equal to or more than 5%.

  • Publication number: 20130004790
    Abstract: In the composite, an aluminum-plated steel sheet and a resin are securely and integrally joined together. Through chemical etching, the aluminum-plated steel sheet is caused to have a surface configuration, in which three-dimensional protrusions having shapes with a minor diameter of at least 0.3 ?m and a major diameter of at least 3 ?m are scattered over a plain part and a portion covered with shallow fine recesses with a diameter of 20 to 50 nm in a state of being distributed adjacent to each other on the plain part accounts for 30 to 50% of the surface area of the plain part. The surface of the three-dimensional protrusions is mainly ceramic containing silicon and the plain part is mainly ceramic containing aluminum. The resin is joined through injection molding with the aluminum-plated steel sheet having been inserted into a metallic mold.

  • Publication number: 20120321802
    Abstract: A method of forming a concrete wall having a substantially uniform exterior surface texture. The method includes the initial step of pouring concrete into a wall form. The concrete is poured from a first mixture and is allowed to cure. After the concrete is cured, the wall form is removed from the resultant concrete base structure. A roughened texture is then created on the base structure. A finishing mixture is then applied to the roughened texture. The finishing mixture may be created by separating the aggregate from a portion of the remaining first mixture. The finishing mixture creates a smooth texture on the exterior surfaces of the initially formed base structure.

  • Publication number: 20120301351
    Abstract: A high etch cleaner for aluminum and aluminum alloy substrates that leads to enhanced corrosion protective performance of a variety of anti-corrosion pretreatments. The cleaner comprises low levels of silicate of from 0 to 250 ppm, 50 to 500 ppm of at least one chelator, and has a pH of from 11.0 to 13.5. The cleaner may be used to etch from 0.5 to 4.0 grams per meter squared from substrates. Substrates treated with the cleaner and then coated with a variety of anti-corrosion pretreatments and outer coatings show enhanced corrosion resistance compared to substrates cleaned with standard cleaners that have low etch rates, high silicate levels and no chelating agents followed by anti-corrosion pretreatments and outer coatings.

  • Publication number: 20120058276
    Abstract: There is disclosed a processing solution for metal replacement for metal aluminum or an aluminum alloy. The processing solution is used for surface processing of an underlying aluminum material. The processing solution for metal replacement removes an oxide film on the underlying aluminum material and suppresses corrosive attack to it to allow a plating film having high smoothness and good plating appearance to be deposited on the underlying aluminum material. The processing solution for metal replacement at least includes a metal salt capable of being replaced with aluminum, and an alkaline compound. A quaternary ammonium hydroxide is contained in the processing solution for metal replacement as the alkaline compound.
