    摘要: A process for the production of oil control rings having a scraper edge formed by a layer consisting of a wear-resistant material. The wear-resistant layer is embedded between two softer layers. Thereafter, the scraper edge is machined and the soft layers recessed by etching to expose the scraper edges.
