Back-ionization

Troubleshooting

Cause

Correction

“Back-ionization” occurs when the powder layer is too thick.

Reducing powder flow often prevents back-ionization, but results in a reduction of the transfer efficiency. Back-ionization also depends on the temperature and humidity.


Very difficult powder materials may require air-conditioning of the coating zone. See also, orange peel effect.
