Abstract
The present invention relates to a method for producing a coating on a gas turbine component, in which particles at least of parts of a material to be applied as coating are accelerated by means of kinetic gas dynamic cold spraying in a spray jet onto the surface (2) of the component (1) to be coated, wherein a reactive gas is fed into the spray jet (6), so that the reactive gas reacts at least partially with the particles of the coating material when the particles impinge on the surface (2) to be coated and/or wherein the deposited layer (9) is heated locally and/or over a large area and impacted with a reactive gas, as well as a gas turbine component produced in this way.
