Method for manufacturing coated article
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.
