Results of laboratory tests and distributions of thickness primer in the automotive industry indicate that the electro-coating process is only partially inhibited when the required value of thickness primer is achieved. This characteristic imposes to consider all the operating parameters in order to achieve a more constant thickness. The effect of combined electro-coating bath movement/pulsed voltage on primer thickness is detected in this paper by proposing suitable experimental set-up and performing experimental. The obtained results point out the negligible effect of movement on the final paint thickness even when a pulsed voltage was applied. The measured electrical resistance of the film and the sublayer of the partially discharged colloid particles explain the experimentally observed negligible variation.

Abstract
Results of laboratory tests and distributions of thickness primer in the automotive industry indicate that the electro-coating process is only partially inhibited when the required value of thickness primer is achieved. This characteristic imposes to consider all the operating parameters in order to achieve a more constant thickness. The effect of combined electro-coating bath movement/pulsed voltage on primer thickness is detected in this paper by proposing suitable experimental set-up and performing experimental. The obtained results point out the negligible effect of movement on the final paint thickness even when a pulsed voltage was applied. The measured electrical resistance of the film and the sublayer of the partially discharged colloid particles explain the experimentally observed negligible variation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
