THE OXIDATION BEHAVIOR OF AMORPHOUS AND POLYCRYSTALLINE ZR-NI ALLOYS

abstract

• The surface reactivity of amorphous and crystalline ZrNi alloys with oxygen have been examined with X-ray photoelectron spectroscopy. Oxidation at ambient conditions (1 atm air and room temperature (RT)) and over the temperature range RT to 300C and at pressures between atmospheric and 10-8 Torr have been studied. The preferential oxidation of zirconium and the structure of the resulting oxide films are discussed in terms of the Cabrera-Mott model. The pressure and temperature dependence appears consistent with the model. The instability of thin ZrO2 films with respect to oxygen absorption into the bulk or subsurface region and electrochemical charge exchange has been observed. A comparative discussion of surface reactivity to oxygen of the crystalline and amorphous alloys is given. 1988.
