Abstract: A method for depositing a ceramic coating on a substrate by spraying a liquid. To accomplish this, first a first coating solution and at least one further coating solution are sprayed and react chemically when they are brought together. The reaction product thus formed forms the coating on the substrate or is converted into the coating in a subsequent further process step. The device has a spray device that ensures that the first coating solution and the further coating solution are brought together immediately before spraying or during spraying itself in the spray device. Alternatively, the device has a first spray device and at least one further spray device, so that the coating solutions are brought together and the reaction that forms the reaction product takes place after spraying on the substrate has occurred.
