Purpose: This article is devoted to methods for predicting the results of surface modification of titanium alloys in glow discharge nitriding. With this advantage, it is given to the analytical criteria as the most appropriate for design automation of processes processing. Design/methodology/approach: The methodology is the position that the nitriding process is a combination of several competing processes leading to the formation of both nitrides, nitrogen diffusion into the depth of the surface and to spray it. The main principle of assessing the intensity of each of them is that each elementary process is the most successful in the case when it created for optimal energy conditions. Findings: Developed a system of analytical criteria - relative energy factors, which qualitatively and adequately reflect the real processes of nitriding of titanium alloys in a glow discharge. Compliance with these indicators were tested in experimental treatment of samples resulting in an energy generating process model. Practical implications: The results were primarily used for computer-aided design modification processes, the optimal choice of the technological nitriding mode, the basis for the software control systems equipment for the processing of titanium alloys. Originality/value: The proposed energy model for the nitriding process in a glow discharge has no current analogues in the world.
