A plasma device for applying a multilayer composite coating includes an arc channel and a powder conduit connected to the arc channel, which is used to supply the material from which the coating is formed. The plasma device has at least two powder conduits at different distances from the arc channel section for simultaneously feeding particles of materials with different thermophysical and geometric characteristics with significantly different melting points, thermal conductivity and particle sizes into the arc channel.

The utility model belongs to the field of material processing by arc plasma flows and can be used in installations for plasma coating and modification of the surface of products.
