Ceramics based on partially stabilized zirconium dioxide are widely used in dentistry. The surface of a ceramic product is subjected to aerodynamic abrasive processing for reliable durable fixing before applying polymer cement. The mechanical properties of a machined thin ceramic layer are largely determined by its phase composition. The method of X-ray phase analysis is used to study the effect of aerodynamic abrasive treatment on the phase state of the surface layers of partially stabilized zirconium dioxide, depending on the type and conditions of formation of the developed microrelief. It is found that aerodynamic abrasive treatment is accompanied by a change in the initial phase composition, i.e., the appearance of a new monoclinic phase. The monoclinic phase is shown to be removed during thermal annealing at a temperature of no less than 1000°C. As an alternative to aerodynamic abrasive treatment prior to the application of polymer cement, it is proposed that the bonded surface be treated with a high-current pulsed beam of low-energy electrons. Such processing creates a developed surface microrelief without introducing a monoclinic phase in it.

基于部分稳定的二氧化锆的陶瓷广泛用于牙科。在应用聚合物水泥之前，陶瓷产品的表面经过空气动力研磨处理，以实现可靠的持久固定。机械加工薄陶瓷层的机械性能很大程度上取决于其相组成。X 射线相分析方法用于研究空气动力磨料处理对部分稳定化二氧化锆表面层相状态的影响，这取决于已形成微浮雕的类型和条件。发现空气动力磨料处理伴随着初始相组成的变化，即新单斜相的出现。在不低于 1000°C 的温度下进行热退火过程中显示出单斜相被去除。作为在应用聚合物水泥之前进行空气动力磨料处理的替代方案，建议使用高电流脉冲低能电子束处理粘合表面。这种处理产生了发达的表面微浮雕，而不会在其中引入单斜晶相。
