Experiments have been carried out to study the tribocorrosion behaviour of low temperature plasma carburised 316L stainless steel under unidirectional sliding in 0.5 M NaCl solution, using a pin-on-disk tribometer integrated with a potentiostat for electrochemical control. It is found that the carburised layer exhibits much better resistance to material removal than the untreated specimen, particularly at anodic potentials. No corrosion pits are observed inside the wear track on the carburised specimen at anodic potentials as high as 750 mV (SCE). The results are discussed in terms of the relative contribution of wear and corrosion to overall material removal by tribocorrosion. (C) 2011 Elsevier Ltd. All rights reserved.
