Abstract

The kinetics and mechanism of thermal oxidation of electrolessly reduced Ni–B and Ni–W–B alloys are studied by precision thermogravimetry and x-ray photoelectron spectroscopy. It is shown that the oxidation is mainly determined by properties of boron oxides. At temperatures over 300°C, the oxidation is accompanied by a sublimation of boron oxides formed. Traces of water and hydrogen in freshly deposited alloys affect significantly both the kinetics of the alloys oxidation and sublimation of the oxides. The vitreous oxide film well adsorbs water vapor and can be readily removed from the sample surface.
