Abstract (en)
[origin: EP1932936A1] The method for coating a component with a multilayer ceramic coating, comprises applying individual layers of the ceramic coating covering one another on the component and supplying the ceramic particles to a coating burner in which the particles are melted partly or completely and then deposited on the component. The ceramic particles with a particle size, which increases from layer to layer, are supplied to the coating burner. On the multilayered ceramic coating, a multilayed top layer is applied. A plasma burner (10) is used as the coating burner. The method for coating a component with a multilayer ceramic coating, comprises applying individual layers of the ceramic coating covering one another on the component and supplying the ceramic particles to a coating burner in which the particles are melted partly or completely and then deposited on the component. The ceramic particles with a particle size, which increases from layer to layer, are supplied to the coating burner. On the multilayered ceramic coating, a multilayed top layer is applied. The ceramic particles for the top layer have larger particle size than the ceramic particles supplied to the coating burner. A plasma burner (10) is used as the coating burner, whose power is adjusted through a variation of the ampacity, hydrogen gas flow and/or the argon gas rate during applying individual layers of the ceramic coating continuously on the component. The thickness of the individual layers of the ceramic coating is 20-50 mu m. The overall thickness of the ceramic coating is 250-650 mu m. The ceramic particles are introduced with a grain size of 75 mu m+10 mu m or -53 mu m + 11 mu m or -90 mu m + 11 mu m to the coating burner for the first layer, with a grain size of -106 mu m + 11 mu m or -125 mu m + 45 mu m or -150 mu m + 75 mu m to the coating burner for the last layer and with a constant grain size of -75 mu m + 10 mu m or -53 mu m + 11 mu m or -90 mu m + 11 mu m to the coating burner for the formation of lower layer. The thickness of the individual layer of the lower layer is 20-50 mu m. The overall thickness of the lower layer is 150-450 mu m. Independent claims are included for: (1) a multilayer ceramic coating; and (2) a component of a gas turbine.
