Methods of deposition of a coating on a surface of a workpiece, working with at least one deposition device, or torch, of thermal spray type, controlled by an associated motor. It is contemplated to perform the deposition step by configuring the torch so as to create two concurrent movements, of which a first movement along a linear path on the surface area to be coated; a second oscillation movement according to an axis of rotation coaxial with said advancement direction; this allows increasing the spray pattern of the thermal spray torch at each stroke resulting in a reduction of the relative movement speed of the torch itself. Also provided are a thermal spray deposition torches and apparatuses for depositing a coating on a surface of a workpiece.
