The Pourbaix diagrams also known as the E-pH diagrams were constructed for hardfacing alloys based on titanium carbide (TiC), niobium carbide (NbC) and tungsten carbides (W2C and WC) at 298K (25oC). Using the thermodynamic data available for the main species at 298K (25oC), Pourbaix diagrams for all these carbides are constructed at a concentration of 10-6M of aqueous species. It was found that the stability of carbides is described only by the immune region of the Pourbaix diagram for carbides. Although passive region has been included in the study, it was unclear from literature if there was a passive film or how protective it was.
