TECHNOLOGY SUPPORT WEAR CAST IRON PISTON RINGS
We describe the influence of technological factors, chemical composition, mechanical properties of cast iron, the parameters of the quality of the surface layer on the wear resistance of cast iron piston rings. The analysis of the causes of reduction of wear - iron piston rings. A variant of the advanced technology fabrication of piston rings and the design of a special device for lapping rings in a condensed package of states that provide increased wear resistance of cast iron piston rings.
