Introduction to the oxide film of zirconia toughened alumina

Zirconia toughened alumina has a certain significance in composition, among which it also has a certain oxide film, so it has a protective effect. The application fields of zirconia toughened alumina all have the requirements of creep resistance, oxidation resistance, corrosion gas resistance, sufficient strength and toughness, as well as good processing and weldability at high temperatures. At the same time, the protective effect provided by its own oxide film supports the ability of zirconia toughened alumina..

1. After the formation of the oxide film, the oxidation reaction rate will significantly slow down, resulting in good protective properties of the film.

2. The density of the oxide film and the stress in the film are the guarantees for the oxygen resistance of zirconia toughened alumina. The density of the oxide film can fully block the contact between zirconia toughened alumina metal molecules and air, and the continuation of the oxidation reaction. Achieve the effect of fully protecting zirconia and toughening alumina.
