Tribological and tribocorrosion behaviour of electrodeposited CoW alloys and CoW-WC nanocomposites

► Wear resistance of CoW improves substantially via impregnation of WC particles by electrodeposition. ► First time reported noble direction OCP shift during sliding experiments in 0.5 M NaCl solution. ► Oxygen reduction rate on tungsten surface plays an important role in deciding the OCP position.
