Influence of Water Vapour on the Rate of Oxidation of a Ni-25wt.%Cr Alloy at High Temperature
Abstract
International audience ; In many industrial applications water is present in the hot oxidant gases to which the metallic components can be exposed in service. The presence of vapor may influence the progress of high temperature oxidation by modifying the structural characteristics of the growing external oxide scales and the kinetics of mass gain as well as of mass loss. The chromia-forming refractory alloys or superalloys are especially concerned since, in vaporcontaining hot gases, the volatilization of their protective oxide scale is enhanced by the formation of oxy-hydroxides according to the equation ½ Cr2O3 (s) + H2O(g) + ¾ O2(g) = CrO2(OH)2(g), with as result a minimization of the mass gain rate when the oxidation progress is followed by thermogravimetry. When the temperature is very high the volatilization of the platinum wire to which the sample is hung may also contribute to this linear mass loss by volatilization, while, one the contrary, a linear mass gain may occur in case of redeposition of a part of the previous volatilized species on the suspension in colder places of the thermobalance. It is thus important, in the mass variations recorded by the thermobalance, to separate on the one hand the parabolic contribution of the oxidation of the alloy, and on the other hand all of the linear mass losses (volatilization) or linear mass gains (recondensation), in order to better characterize the resistance of the alloy to high temperature oxidation. This uncoupling can be done for example by exploiting the mass gain curves according to a method previously adapted to the assessment of both the parabolic and volatilization constants from the mass gain curves recorded during oxidation in dry air. The aim of the present study is to test Ni25Cr-type samples cut in the same ingot obtained by equiaxed solidification, in dry air and in a humidified air with the same thermo-balance and with the same parameters (heating and cooling rates, temperature and duration of the isothermal stage), in order to clearly reveal ...
