Abstract

We determine the possibility of guaranteeing the regulated level of surface hardening by oxidation, nitriding, and oxynitriding from a controlled atmosphere within the temperature-time range of aging of the VT22 titanium alloy (T = 600–650°С; τ = 2–8 h). The efficiency of oxynitriding in a dynamic vacuum with inleakage of an active gaseous mixture with composition 25% O₂ + 75% N₂ into the reaction chamber is established. The gas-dynamic parameters of oxynitriding are optimized.
