Zirocnia Ceramics:

Zirconia ceramics are high temperature insoluble compounds, no melting point, high temperature creep resistance, reaction sintered silicon nitride without binder has a load softening point above 1800 ° C, silicon nitride ceramics have a low coefficient of friction, high temperature and high speed Under the condition of, the increase of friction coefficient is also small, so it can ensure the normal operation of the mechanism, which is one of its outstanding advantages. The sliding friction coefficient of silicon nitride ceramics when starting to grind reaches 1.0 to 1.5. After precision running in, the friction The coefficient is greatly reduced and remains below 0.5, so silicon nitride ceramics are considered to be self-lubricating materials. The ceramics sintered at high temperature are composed of many polycrystalline aggregates of crystallites, which inevitably exists grain boundaries The atoms on the grain boundary cannot be arranged in an orderly manner, and have a transitional nature, and the structure is relatively loose. Therefore, the grain boundary is an important channel for the rapid diffusion of atoms (ions). It is a fragile part of the ceramic in the acid-alkaline environment. Silicon nitride ceramics in acid solution Corrosion characteristics in the alloy are closely related to the number and crystallinity of grain boundary phases. Schilm [13] et al. Took six kinds of silicon nitride samples as experimental materials and used 1N sulfuric acid solution as the etching solution for corrosion. Several factors affecting the corrosion of silicon nitride ceramics were obtained (1) The effect of SiO2 content With the increase of SiO2 content in silicon nitride ceramics (22 ～ 42%), the reaction rate constant gradually decreases, and the initial corrosion rate even decreases by more than two orders of magnitude.
