Abstract
A treatment jet or beam, e.g. from a high velocity oxygen-liquid fuel (HVOF) spray gun, has an axis intersecting the surface of a rotor at a given point. The rotor has a profile which progresses helically along it. The point is traversed along the rotor while keeping the point at the same position on the rotor profile. In particular the jet axis is moved parallel to the rotor axis while the rotor is rotated in synchronism.
