In this work overlays deposited by Plasma Transferred Arc (PTA) are assessed under simulated slurry erosion-corrosion to establish the degradation mechanisms.

The materials used in this study are WC-metal matrix composites (MMC) incorporating NiCrBSi and FeCr alloys as the matrix phases. The WC hard phase provides a good wear resistance to the composite and the matrix material confers support to the hard phase and ductility.

The influence of the binder materials in the erosion-corrosion performance of the MMC overlays was evaluated as a function of temperature and sand concentration to provide information for materials selection in the oilsands industry.
