<p>PURPOSE: To efficiently coat the inner walls of bores, pipes, or the like, by using a plasma spray apparatus having a turnable supply member, a plasma gun shaft member which is connected thereto and a plasma gun head member which is fixed to one end of the plasma gun shaft member and has a plasma torch allowing plasma to flow out in a transverse direction. CONSTITUTION: This plasma spray apparatus is provided with the supply member 2 which has a central longitudinal direction shaft 47 and is suitable for being controlled to a source of electric energy and powdery, liquid and gaseous media and the plasma gun shaft member 3 having first and second ends 5 and 3a. This first end 5 is coupled to the end of the supply member 2, and the plasma gun heat member 4 having the plasma torch for allowing the plasma to flow out in the transverse direction is connected to the second end 3a. A bearing member 11 is disposed within a housing member 1 in order to make the supply member 2 turnable around a shaft 47 together with the plasma gun shaft member 3 and the plasma gun head member 4.</p> |
