RESEARCH OF WEAR RESISTANCE OF PISTON RINGS WITH LASER PROCESSING ON THE BASIS OF THE ACCELERATED TESTS
Laser hardening of the details of cylinder-piston group is examined. Piston rings were exposed to laser hardening by two variants: on СО2-laser "Comet-2" and on the laser technological complex designed by the authors, which includes solid-state laser LTN-103 and the machine tool with numerical control ТПК-125ВН. It has been stated that laser processing of piston rings both raises wear resistance and reduces deterioration of serial cylinder plugs.
