Abstract

© 2020 Elsevier Ltd.In this study, WC/C coating was applied on beryllium (Be)-copper (Cu) mould alloy by arc physical vapor deposition (PVD) as a corrosion and wear protection barrier against alumina ball in a 3.5 wt% NaCl solution. Tribocorrosion tests were carried out in a triboelectrochemical cell using a ball-on-plate tribometer integrated with a potentiostat for electrochemical control. The results showed a clear improvement of wear resistance on the WC/C coating without reducing the corrosion behavior in a 3.5 wt% NaCl solution.
