<p>The determination and regulation of parameters for thermal spray deposition of a coating (21) of fine particles on a substrate (22) with a spray torch (20) comprises: (A) determining along the spray jet (30) at each of the distances (d1 to dn) some spray parameters such as powder flow rate, gas flow (24) rate and electric current density; (B) automatically regulating the distance between the outlet of the torch and the substrate to a value essentially equal to one of the determined distances; and (C) continuously regulating the spray parameters to maintain them essentially constant. An independent claim is also included for a device (10) for determining and regulating the parameters of thermal spray deposition on a substrate.</p> |
