popup.description2
A new solution of the scientific and technical problem of intensification of gas nitriding for two-phase titanium alloys by preliminary modification of its surface by the method of cold surface plastic deformation is proposed. For example, for titanium alloy VT22 surface microhardness increases by 50%, and the depth of the hardened layer thickens by 30% compared to nitriding without prior deformation. The scheme and regime of deformation-diffusion treatment are recommended, which with regulated volumetric hardening of VT22 alloy double its wear resistance in tribo-pair with bronze BrAZhN 10-4-4 and reduce friction coefficient by 30% compared to nitriding without prior deformation. Technological recommendations for combined deformation-diffusion modification of surface layers of structural elements of aircraft made of titanium alloys VT22, VT6 and T110 for the State Enterprise "ANTONOV" have been developed.
