Abstract [eng] In this study tungsten carbide/cobalt (WC-Co) coatings sprayed by high velocity oxygen fuel (HVOF) deposition were investigated. For the comparative purposes the bulk WC-Co sample cutted from the WC-Co hot roller was studied as well. It was found, that WC-Co bulk sample cutted from the WC-Co hot roller was coated by WO2 layer as a result of the 900 °C temperature air annealing. No connection between the WC-Co coating oxidation and its peeling as a result of the air annealing was found. The most stable coating in terms of peeling was the most oxidized one. According to XRD analysis, formation of the surface oxide layer inhibits further oxidation of the deeper layer of the coating. Change of the coating morphology was observed as a result of the air annealing starting at 500 °C temperature.
