An experimental study on wear performance of electrolytic multilayer cu-ni-cr coated abs under different test forces

Abstract

Plastic materials are widely preferred in many applications due to being light and cheap in addition to being manufactured easily with various manufacturing methods like injection molding or additive manufacturing. One of the most used plastic material ABS (acrylonitrile butadiene styrene) is sometimes coated to increase its wear and corrosion resistance. In this study, investigating the effect of coating and test forces on wear behavior of injection-molded ABS specimens at room temperature were focused. For this purpose, ABS specimens were manufactured with injection molding technology and some samples were multilayer Cu-Ni-Cr coated step by step. Then, surface roughness values of prepared coated and uncoated specimens were measured by surface roughness profilometer. Subsequently, the micro view of the coated sample was obtained from an optical microscope after cutting the sample with the precision cutting machine. Lastly, the wear performance of coated and uncoated samples was tested under various loads such as 5N, 7N, and 10N by using pin-on-disc test equipment. In conclusion, surface roughness and wear level of samples were determined besides the average friction coefficient and friction forces. The results show that multilayer Cu-Ni-Cr coating affects the friction forces and average friction coefficient values significantly. © 2021, TUBITAK. All rights reserved.
