Calibration method of coating thickness standards

Annotations languages:

The paper describes a new method regarding calibrating the coating thickness standards, which is based on the groping of the surface of thickness standards. The croping results enable to calculate the functions of the surfaces that are not covered and thereafter calculate the assumed profile and the functions of surface under the coating. Coating thickness is determined as a distance between the profile of a surface of the coating and the assumed profile under the coating.
