FIELD: engines and pumps.
SUBSTANCE: application: invention is related to the field of propulsion engineering, namely to technology for strengthening of piston grooves by method of spark strengthening, and may be used for strengthening of aluminium piston grooves in internal combustion engines. Method for strengthening of piston grooves in internal combustion engine is realised by means of thermal action at local zone of strengthened groove of piston by spark charge, which is formed at atmospheric pressure with frequency of pulses of 7 Hz and energy of spark charge of 0.1 mJ.
EFFECT: increased operational reliability of pistons.
