PURPOSE:To prevent attachment of spraying particles to the part of a base material not necessary to form a coating film through throttling of a plasma jet and to secure the attaching amount of the film without causing prolongation of the spraying time. CONSTITUTION:With the plasma spraying method according to the present invention, a coating film 10 is formed by generating arcs between a cathode 2 and an anode nozzle 1 and spouting a plasma jet consisting of spraying particles 3 and working gas 4 to the surface of a base material 7. An electromagnetic coil 11 is installed around the plasma jet, and a current is fed to this coil so that a magnetic field is generated. |
