Abstract
The article deals with the issues of determining the thickness of layers and coatings for various purposes in metallographic research. The role of the material for filling metallographic sections in determining the layer thickness is demonstrated. It is shown that when filling the sample with plastic masses, the error in determining the layer thickness can be 0.2...0.4 microns, which is significant for thin layers. Sample preparation options for determining the thickness of titanium nitride layers with a thickness of 1 microns or less are considered. It is shown that with the optimal method of sample preparation, it is possible to visualize a layer less than 1 microns thick, and also determine its thickness in the image processing program.
