Characterization of various coatings in terms of friction and wear for internal combustion engine piston rings (original) (raw)

This research examines the effectiveness of various coatings on friction and wear characteristics in internal combustion engine piston rings. The study highlights the significant role of friction losses in engine efficiency and explores alternative coatings designed to reduce these losses while also addressing environmental concerns associated with traditional hard chromium coatings. Experimental results indicate that HVOF WC-CrC coating demonstrates superior performance, offering potential pathways for both enhanced engine efficiency and reduced ecological impact.
