  • Patent number: 7595095
    Abstract: A method of making a coated article is provided. The method includes electrostatically depositing powder onto a metallic article to be coated using an electrostatic spray gun while the metallic article is being rotated around its axis such that the powder is deposited around the entire circumference of the metallic article at least in a radially outward peripheral region having projections and depressions and that the powder deposited on top of the projections is larger in thickness than the powder deposited in other parts of the metallic article. Melting of the powder is performed by induction heating the metallic article to make a coating film adhere to the metallic article.

  • Publication number: 20060134344
    Abstract: After forming a primary powder bed at a toothed portion of an article, such as a gear or a spline shaft, by electrostatic powder coating process, the powder bed is removed from crests of teeth in the toothed portion by a specified thickness by scraping it off while sucking up the scraped powder. Next, the electrostatic powder coating process is performed again to form a secondary powder bed over the entire surface of the toothed portion. Then, the primary and secondary powder beds are melted or fused by induction heating to thereby form a coating film of a substantially uniform thickness.

  • Patent number: 7048972
    Abstract: After forming a primary powder bed (i.e., powder layer) at a toothed portion of an article, such as a gear or a spline shaft, by electrostatic powder coating process, the powder bed/layer is removed from crests of teeth in the toothed portion by a specified thickness by scraping it off while sucking up the scraped powder. Next, the electrostatic powder coating process is performed again to form a secondary powder bed/layer over the entire surface of the toothed portion. Then, the primary and secondary powder beds/layers are melted or fused by induction heating to thereby form a coating film of a substantially uniform thickness.
