FIELD: process engineering.
SUBSTANCE: invention relates to production of heterogeneous materials and may be used in ship and aircraft building, chemical machine building, etc. Proposed method comprises making holes in part from lower-infusibility material compared with that of another part and acting on the former by rotary cylindrical tool. Metric or conical thread is made in said holes. Tool is revolved in direction mating that of thread turns.
EFFECT: higher adhesion in, for example, steel-aluminium joint.
