Study on Friction and Wear Performance of Plasma-Sprayed Metal Oxide Ceramic Coatings
Abstract:
Paper transferring gripper is a key part of printer. In this work, plasma spray technology was adopted for the coating of 5 different metal oxide ceramic layers on metallic substrate. The friction and wear performance of different plasma-sprayed metal oxide ceramic coating on the gripper surface were comparatively studied by friction and wear test. Results suggested that compared to 100% Al2O3 and 100% Cr2O3 ceramic coatings, Al2O3/Cr2O3 composite coatings had a higher friction coefficient and wear amount. Abrasive wear was the dominant wear mechanism for Al2O3/Cr2O3 composite coatings, while fatigue wear was dominant for 100% Al2O3 and 100%Cr2O3 ceramic coatings.
