Abstract
Results of the thermodynamic analysis of the probability of formation of chemical compounds in the «Ti-C-N-O-B» system are presented in this paper. The ranking of the formation of chemical reactions as a function of temperature (T = 100...1200°C) and air pressure (P = 1.33∙10-8...1∙105 Pa) is carried out. It is shown, that titanium will interact with oxygen most actively, forming a interstitial solid solution with the subsequent T = 900°C titanium boride. Reduction of air pressure is not likely to reduce the formation of compounds containing formation of oxides; following the probability, nitrides will be formed, then carbides and up to temperature oxygen and nitrogen. Thus, at the temperature T = 800°C, the available compound B2O2 will be decomposed and will not be formed at the pressure below P = 1.33∙103 Pa.
