“…The reasons are as follows: first of all, oxide films with porous and cracks will form during the oxidation. These oxide films are very easy to flake off, and will definitely decrease wear resistance [1][2][3][4][5][6][7][8][9][10]. Additionally, it has been proved that the strength of the cemented carbides is weakened because of surface oxidation [4][5][6][11][12][13].…”

“…As for the oxidation of cemented carbides, many results have been reported [1][2][3][7][8][9][10][13][14][15][16][17]. Kinetic analysis, the macro-, and micro-structure and the phase constitute of oxide scales are the most important aspects of the investigation of oxidation.…”

“…Attaining the curves of mass gain or the thickness of the oxide scales vs. oxidation time by isothermal method and calculating the apparent activation energy (E a ) by isothermal or non-isothermal method are the major task of kinetic analysis. Barbatti et al [7] have reported that the linear law or parabolic law of mass gain vs. oxidation time was influenced by temperature. E a was influenced by many factors, such as consist of cemented carbides and oxidation temperature [2,3,8,9].…”

“…From the previous literature, we know that the oxide scales formed on a WC-Co substrate mainly consist of WO 3 previous researches have indicated that the oxidation resistance of cemented carbides was improved by the increase of Co content and the addition of cubic carbides, such as TiC and/or (Ta, Nb)C [1][2][3]7,9,14]. However, the oxidation resistance was decreased when Co binder was partly substituted by Ni binder because of the decrease of complex oxide (Co, Ni)WO 4 content [15].…”

AbstractIn this study, the oxidation behaviour of an iron matrix cermet containing 50 % vol. Ti(C,N)was investigated before and after heat treatment by oxidation tests performed in static air at temperatures between 500 °C and 1000 °C. The oxidation mechanism for this type of composite materials was established and it was found that the heat treated material presents lower mass gain than the as-sintered material at the early stages of the oxidation, due to the volatilization of oxides. The oxidation behaviour of the sintered cermet was compared to those obtained for two commercial materials used in the fabrication of cutting tools, a highspeed steel and a cemented carbide, revealing a higher oxidation resistance for the iron matrix cermet due to the formation of a self-protective layer during the oxidation process.
