Process for the electrophoretic coating of workpieces and coating equipment

摘要

A process for the electrophoretic coating of workpieces with a coating medium, in particular paint, and a coating installation (10) are described. In the method, at least one workpiece is immersed in the coating medium. With a voltage source (20, 24a, 24b, 24c, 24d), a DC voltage is applied between the workpiece and at least one electrode (18) immersed in the coating medium. The DC voltage is continuously increased substantially continuously during virtually the entire coating duration in such a way that the coating current density at the workpiece surface remains substantially constant over time.
