摘要:
The present invention relates to a novel process for coating objects by means of direct current, in which process an adjustable DC voltage is pulse-modulated with an adjustable AC voltage. The process is useful for electrochemical coating of objects with resinous coating material. Preferably, the pulse modulation of the DC voltage is limited to certain time intervals during the coating process and the pulse modulation is connected and disconnected with an adjustable duty ratio.
