Innovative Processing Technology of Chromium Carbide Coating to Apprise Performance of Piston Rings 2012-01-2327

A chemical vapor deposition method for preparing high-quality chromium carbide coatings was developed. The resulting coatings exhibit high adhesion and increase wear resistance of the cylinder piston group components as compared to common coatings prepared by electrolytic chromium plating. The operation performance of the coatings was tested using scrapper piston of the Raba-Man diesel engine of Ikarus bus and compression and oil scrapper rings of the diesel engine 10D100. It was found that chromium coatings prepared by the method proposed are characterized by relatively low coefficient of friction and high corrosion resistance.
