FIELD: electrical engineering. SUBSTANCE: mixture of current-conducting component powders is deposited onto heat-conducting substrate by plasma evaporation. This component contain Ni, Cr, Mo, W, Co, Al, Ti alloy, and insulating component Al2O3 components in the form of alloy) taken in proportion, mass percent: Ni - 37.7-76.6; Cr - 8.5-20; Mo - 3.0-11.5; W - 4.3-7.0; Co - 5.0-16.0; Al - 1.6-4.9; Ti - 1.0-2.9. In powder mixture, proportion of insulating and current-conducting components is as follows, mass percent: insulating - 70-92; current-conducting - 8-30. EFFECT: improved reliability of heater.
