The Oxidation Mechanism of Metal-Carbon Alloys and Carbides

  • Karl Hauffe


As is well known, metal carbides are the bases of the hard metals, which owing to their hardness and strength at high temperatures are of tremendous technological significance. So that full advantage may be taken of this great strength at high temperatures, continuing effort must be made to improve the scaling stability of these hard metals. Since the explanation of the oxidation mechanism is rather difficult due to the presence of carbon in the alloys, it is not surprising that people have been concerned with this complex question in a purely empirical way. Wagner and co-workers1 have attempted to determine experimentally the fundamental relationships describing the effect of the carbon during the oxidation of carbon-containing metals and carbides in terms of thermodynamic and kinetic considerations. Of great importance for resistance to oxidation is awareness of the conditions under which gaseous CO and CO2 are formed, since these break up the protecting oxide film and thus cause an increased oxidation rate.
