Evaluation of electrochemical boriding of Inconel 600

► Electrochemical boriding has been performed to form very hard, dense and homogeneous boride layers on Inconel 600. ► In 15 min process duration resulted in very thick boride layers. ► Tribological properties of borided Inconel 600 were superior to the unborided Inconel 600. ► Ni2B and Ni3B phases were obtained as the predominant phases on top of the borided surfaces.
