Abstract:

In the electrodeposition painting of mild steel panels, defects are induced at higher electrodeposition voltages. Of these defects, pinholing appears to be the mose serious and it occurs even after the surface has been coated at lower voltages with a thin, uniform coating. It probably originates from the conversion of electrical energy into heat energy which causes local boiling of occluded solvent in the film deposited on the work piece. Author
