FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular, to heat treatment of alloys based on gold, and can be used in production of low-current sliding contacts (LSC), used in collectors of devices and systems. Method includes heating a contact pair, consisting of a ring and a brush made from an equimolecular alloy ZlM-80, in a protective atmosphere to temperature of 350 °C at a rate of not more than 0.2 deg/s, holding at said temperature and cooling in a vacuum at a rate of not more than 0.2 deg/s.
EFFECT: technical result is high wear resistance of LSC.
