Abstract: Electric fields induced by
ring and pin electrodes in electrostatic charged powder spraying
technique are analysed. The fundamental formulae to describe
these fields have been built up. These formulae could be used to
design electrostatic charged powder spraying system. The
charging effectiveness of ring and pin electrode is
experimentally investigated and compared each other. The
performance of ring electrode is better than that of pin
electrode.
