Influence of diffusion siliconizing and boron–siliconizing in chlorine-containing environments on the structure, composition, and protective properties of TZM molybdenum alloy
Theoretical calculations of the physicochemical conditions of molybdenum-based alloys' siliconizing and boron–siliconizing processes were carried out. Based on the obtained data, the phase composition and its quantitative ratio in the coatings were predicted. The theoretical calculations were experimentally confirmed. The coatings' microstructure, phase, and chemical composition obtained by siliconizing and boron–siliconizing TZM molybdenum alloy in a chlorine medium were studied. The thickness and microhardness of protective coatings are determined. The heat resistance of the obtained coatings in an air atmosphere at 800⁰C for 48 hours was investigated. A recommendation for further use is provided.
