Comparison of Wear Resistance of Chromium Coatings for Piston Rings using Pin-on-Disc Test and Engine Test

Popis výsledku v původním jazyce

This paper deals with testing of hard chromium coatings, which are used for piston rings. There were tested the standard hard chromium, porous chromium and composite chromium coatings. Wear resistance was tested by Pin-on-DISC method and by engine test.Coatings for Pin-on-Disc test were deposited on a steel plate. Al2O3 and WC balls were used as a counter part. Engine test of coatings was performed on a diesel passenger car engine. Coating used for engine test were applied to piston rings made of ductile cast iron. The engine was tested on a engine test bench. The evaluation was performed by optical microscope. Loss of material on the piston rings was measured by micrometer. The standard hard chromium coating showed the highest wear so result were related to this coating. The rate of wear depends on the type of counter part. Results of individual test methods are not sometimes comparable.
