摘要： Corona discharge electrodes are coated with compressed dielectric materials. A corona discharge electrode is placed under tension and coated with a molten, viscous dielectric material, such as glass, while under tension. The dielectric material is allowed to cool so that the dielectric material becomes bonded securely to the corona discharge electrode. The tension upon the corona discharge electrode is released thereby causing a compression of the dielectric material adhered thereto. The resulting dielectric coated corona discharge electrode has a substantially improved life and delivers substantially uniform currents.
