  • Plasma spraying apparatus
    Patent number: 9802212
    Abstract: A plasma spraying apparatus includes a main torch and an auxiliary torch. The main torch includes a first electrode including a spraying material discharge hole, a first mantle, and a first insulator including a first plasma gas introducing port. The auxiliary torch includes a second electrode, a second mantle, and a second insulator including a second plasma gas introducing port. A spraying material supplied from the spraying material discharge hole is melted at the axial center of plasma that is formed on the central axis of the first electrode by the first electrode and the second electrode, and a gas introducing part that introduces gas is provided on an inlet side of an opening part and/or in a tapered part provided between the opening part and the first insulator in the first mantle.
