Slide element, e.g. an i. c. engine piston ring, has a slide surface with an ion plated chromium nitride coating containing boron for increased detachment resistance

摘要

A slide element, comprises a slide surface with an ion plated boron-containing chromium nitride coating having a specified mono chromium nitride preferred orientation. A slide element has a slide surface with an ion plated chromium nitride coating which contains CrN with a (111) preferred orientation and 0.05-20 wt.% boron. Preferred Features: The coating may also contain /} 15 wt.% oxygen and/or carbon.
