Studies on wear properties of carbide coating on case carburised steel

摘要

Abstract The wear behaviour of plasma sprayed silicon carbide coating on EN-353 steel substrate is experimentally investigated in unlubricated conditions. Experiments are conducted at different loads (load, 10 N and 20 N) with room temperature and 1 m/s sliding velocity. Wear tests are carried out by dry sliding contact of coated EN-353 steel pin as counterpart on a pin-on-disc wear testing machine. The coated specimen is characterised by hardness, microstructure and sliding wear resistance. Wear studies showed that the comparison between plasma sprayed silicon carbide coating on EN-353 steels the uncoated one. It is observed that the EN-353 steel plasma sprayed silicon carbide coating exhibited improved tribological performance.
