Abstract

A method of monitoring and controlling thermal spraying methods for coating the surface of substrates. During the spraying process, a substrate surface temperature is measured as a characteristic variable for the transferred layer mass or layer thickness, and, in the event of deviations from the nominal value, at least one method parameter that is significant for the transferred layer mass or layer thickness is changed. The method permits the creation of layers having a predetermined transferred layer mass or layer thickness and a narrow layer thickness distribution over the coated surface.
