Title: Effect of N2 sintering atmosphere on the hardness of sol–gel films of 3mol% Y2O3-stabilized ZrO2
Authors: Díaz-Parralejo, A.1, Ortiz, A.L. alortiz@unex.es, Rodríguez-Rojas, F.1, Guiberteau, F.1

Subjects: Zirconium oxide, Thin films, Sintering, Nitrogen, Atmosphere, Gelation, Nitriding, Hardness
Abstract: Abstract: A one-pot approach to hardening ZrO2-based films prepared by the sol–gel method is presented. It entails performing the sintering in a nitrogen atmosphere, instead of in the conventional air atmosphere. It is shown that, when the sintering temperature is high enough, gas nitriding takes place in the ceramic film, leading to a 15% increase in its hardness. This occurs because more nitrogen solutes are incorporated into the crystal lattice of the 3YSZ host, forming solid solutions (i.e., greater solid–solution-effect hardening). The proposed gas nitriding is simple and cost-effective, and adds no additional steps to the processing routine. This suggests that it may have an important role to play in the fabrication of hard ceramic films from liquid precursors. [Copyright &y& Elsevier]
