Influence of the Structure of VT22 Alloy on the Surface Hardening in the Course of Deformation-Diffusion Treatment

摘要

We determine the influence of the structural factor on the deformation-diffusion treatment of VT22 titanium alloy. It is shown that the improved complex of physicomechanical characteristics of the hardened surface layers (the level of surface hardening, surface quality, and structure) can be obtained after the deformation-diffusion treatment of VT22 alloy in the as-delivered state. The preliminary standard thermal treatment of alloy negatively affects these characteristics.
