Testing of the Oxidation Resistance of MgAlON Materials with Non-isothermal Oxidation Method
Abstract
In order to establish a standardized testing method for the oxidation resistance of refractory materials, one of their most important properties, China national standard GB/T 32329-2015 has been issued in 2015, which title is “Test method for oxidation resistance of oxynitride materials—non-isothermal oxidationâ€. GB/T 32329-2015 provides a standard characterizing method for oxidation resistance. In this paper we validate this standard through testing the oxidation resistance of six MgAlON samples with the non-isothermal oxidation method described in this standard. We conclude that the oxidation resistance property of MgAlON materials could be well described with these indicators: the oxidation weight gain per unit area, the initial oxidation temperatures and the maximum oxidation rate temperatures. Our experiments show that this method is scientific and feasible.
