FIELD: process engineering.
SUBSTANCE: invention relates to permanent connection of parts made of alloys based of titanium nickelid (TiNi, nitinol), particularly, to to diffusion welding using liquid phase. Proposed method comprises cleaning parts surfaces of oxides and bringing them in contact. Then, they are heated in vacuum and cooled down. Parts are heated to 990-1130°C and cured for 10 s - 5 minutes. In compliance with first version, parts are bonded via substrate from alloys based of titanium nickelid. Said alloy contains 0.05-0.2 wt % of oxygen. In compliance with second one or both parts contain 0.05-0.2 wt % of oxygen.
EFFECT: higher mechanical properties, higher process efficiency.
