Abstract
The plasma spray apparatus for the coating of the inner walls of bores and tubes essentially comprises a housing, a supply member, a plasma gun shaft member and a plasma gun head member. The plasma torch created in the head member escapes transversely with regard to the central longitudinal axis of the plasma spray apparatus. The supply member is rotatably received in the interior of the housing and is driven by an electric motor and a gear box. The supply member comprises a swiveling coupling member by means of which the plasma gun shaft member is connected to the shaft member. Thus, the rotatable shaft member can be radially deflected with reference to the axis of rotation. Thus, the head member fixed to the free end of the shaft member can be radially adjusted. With such a plasma spray apparatus, bores and tubes having greatly varying inner diameters can be reliably coated.
