FIELD: metallurgy.
SUBSTANCE: here is claimed procedure for strengthening items of titanium alloys. The procedure consists in heating surface of an item in nitrogen medium; also, heating is performed with a concentrated heat source with density of power 103-104 Wt/cm2, current strength 80-150 A and rate of source transfer relative to an item - 0.005-0.01 m/sec.
EFFECT: increased wear and corrosion resistance of items of titanium alloys.
