Abstract: An electron beam is radiated on an ion-plating material to heat and evaporate this material, thereby generating a vapor flow of the material. The vapor flow of the material is converged by a hood-like electrode, and at the same time, a positive voltage is applied to the electrode to attract thermoelectrons from the material. The vapor flow is ionized by the thermoelectrons. The converged and ionized vapor flow is deposited on a surface of a strip, thereby performing ion plating.
