Relationship between electrostatic powder coating thickness measurements at different points on uneven surfaces

Abstract

Measure relation of electrostatic powder coating thickness at diferent points on irregular surfaces. In this work, we found the relation between the thickness measures at diferent areas of a irregular surface, by the electrostatic powder coating on pieces with five diferent geometries and varyin slightly parameters like potential and application distance. At the products where the electrostatic powder coating are used, the thickness measure is an importante quality characteristic, however on the irregular surfaces is so noticeable when the thickness measure is not uniform on the entire piece. But when it is known that the thickness ratio varies from one area to another of the same piece, it is easier to establish a methodology that allows the process to have a measure of uniform thickness.
