Abstract

Research results of chemical reactions in picture formation by laser marking on the surface of beryllium gyroscopic details by investigations of thermodynamic analysis are given. Conductivity control ability of contrast picture created by laser marking by varying the composition and partial pressures of the gaseous medium components is revealed. The results of X-ray analysis confirming the data of analytical calculations are presented.

Keywords: laser marking, thermodynamic analysis, isobaric-isothermal potential, electrical conductivity, partial pressures of gas medium components.
