Abstract
The present invention discloses a method of correcting the shape of a spray-formed article which has a concave bowing relative to the working surface of the article. Specifically, deviations of such articles from a desired predetermined shape are corrected by applying sufficient heat to a non-working surface to permanently remove at least a partial amount of the concave bowing while leaving the working surface substantially unmarred. This process is repeated iteratively until the article achieves the predetermined shape.
