METHOD FOR MANUFACTURE OF OPARTS Russian patent published in 1996 - IPC

FIELD: aircraft motor building. SUBSTANCE: after primary mechanical working which includes making of central hole 2 in blank 1, the latter is subjected to heat treatment - ageing of the first stage, and then, its central part is hardened by explosive hardening. This is followed by mechanical working of disk body and disk body 5 is hardened by explosion of ring-shaped explosive charge 9 triangular in cross-section. Then blank 1 is subjected to ageing of the second stage and final mechanical working. EFFECT: higher quality in manufacture of disks of high-pressure turbines of gas-turbine engines. 2 cl, 7 dwg
