ABSTRACT:
In order to effect thermal spraying of an inner surface at an optimal thermal spray distance depending upon thermal spray conditions, a method for thermal spraying of the inner surface includes the steps of inserting a thermal spray material bending member 3 having an inclined guide plane 8 at its tip face into the opening so as to face a thermal spray gun 1, moving the thermal spray gun 1 and the thermal spray material bending member 3 in synchronization with each other while maintaining the distance between the thermal spray gun 1 and the thermal spray material bending member 3 at a predetermined value and changing the direction of a thermal spray jet 4 jetted straight from the thermal spray gun 1 by the thermal spray material bending member 3 to spray the thermal spray jet 4 on the inner surface of the opening.
