LIGHT ALLOY PISTON

摘要

In a pressure-diecast light alloy piston, a ring carrier made of a metallic material having pores filled by the piston materials is embedded in the piston casting adjacent to the first ring groove. In order to provide a strong joint to the piston base body, the ring carrier consists of cold-compacted chips of austenitic cast iron and there is a metallic bond between the chips and the piston material.
