<p>When controlling and/or determining the thicknesses of layers or surface coatings there is chosen a coating composition that incorporates a fluorescing indicator substance, the proportions of which in the coating composition can be measured by X-ray fluorescence. The coating composition is applied to a substrate surface in solution, slurry or molten form and the thickness of the coating, or layer, is controlled and/or monitored in accordance with the intensity of the light which fluoresces from the the coating.</p> |
