The problems of resource extension and recovery of the piston–cylinder parts of internal combustion engines are considered. A method for modelling working conditions of pair ‘groove–ring’ of motors is developed, and durability of aluminium Al-25 alloy with electrospark coatings of different composition paired with a chromium alloyed steel under high-temperature fretting process is carried out. Optimum modes of hardening treatment for piston ring grooves of pistons of internal combustion engines are determined.

Key words: aviation ground equipment, internal combustion engine, piston–cylinder group, wear resistance, electrospark doping, fretting corrosion.
