THE PROBLEM OF INSTRUMENTAL STUDIES OF ELEMENTARY COMPOSITION OF THIN DIFFUSION COATINGS ON IRON-IRON ALLOYS
This article presents the results of elemental analysis of diffusion coating on steel 45. The elemental composition of the diffusion coating has a dependence on the method of investigation. In the region of «heavy» elements, the range of values does not exceed 10 %, whereas in the region of «light» elements and, in particular, with respect to boron, the spread reaches 200 %. The use of reference samples for calibration of the EDX analytical system allows to significantly improve the accuracy of the determination of light elements with an atomic number less than 14 (Z = 14).
