METHOD OF HEAT TREATMENT OF SMALL-SIZE THREADED PARTS OF ALLOYED STEEL Russian patent published in 1997 - IPC

Abstract RU 2094489 C1

FIELD: metallurgy. SUBSTANCE: threaded parts that can find use in instrumentation engineering, space technics, and electronics are heated under vacuum on contact ceramic heating element at 550-600 C for 5-10 min and then oxidized on the same heater in air for 10-15 min. EFFECT: increased antifriction characteristics, reduced effort and power consumption. 4 cl, 1 tbl
