PROBLEM TO BE SOLVED: To reduce the loss of powder by enhancing applicability to powder having a high m.p. and to set the plasma spraying range with a high accuracy by effectively introducing powder into a melted state. SOLUTION: This device is provided with insulated housing 2 attached to casing 1, a cathode electrode 5 attached to the inside of the casing 1 in a projected state, an anode electrode 6 disposed in a state opposite to the cathode electrode 5, plasma gas exhaust nozzle charging plasma gas to the vicinity of the tip of the cathode electrode, a powder charging port disposed at a position in the inner direction of the plasma injection nozzle of the anode electrode 6 and charging powder and a cooling liq. feed port feeding liq. for cooling to a cooling flow path around the anode electrode 6. |
