Types and characteristics of metallization of zirconia ceramic rods

The zirconia ceramic rod is processed by isostatic pressing technology, and forms a uniform, dense and smooth ceramic layer and transition layer at high temperature and high speed. Because of the advanced production technology and high cost, it is suitable for the use of precision ceramic parts, and its wear resistance is stronger than other ceramic rods, and it is generally used as a high wear resistance place.

The metallization of zirconia ceramic rods is to paste the ceramic rods on the inner wall of the metal with high temperature resistant strong adhesive, and form a firm anti-wear layer after being heated and solidified. The production process of this kind of product is relatively simple, the production cycle is short, and the cost is relatively low. Technical specifications: Mingrui Ceramics has ceramic rods of various sizes, and can also be customized according to customer needs. Metallized ceramic rods are basically not limited in size, and diameters from 0.5mm to 160mm or even larger can be produced.
 
Ceramic rod drilling is to use high temperature resistant strong adhesive to paste the ceramic rod with a hole in the middle to the inner wall of the metal, and at the same time, the ceramic is firmly welded to the inner wall of the steel sleeve through the small hole with the spot welding process. In order to protect the solder joints, a ceramic cap is screwed on. Each porcelain rod is not only close to each other, but also each forms a corresponding angle, so that the porcelain rods are tightly connected, and there is no gap; when the last one of a circle is tightly embedded, a 360 mechanical self-locking is formed between the porcelain rods force. The production process of this kind of product is relatively complicated, the production cycle is long, and the cost is high.
 
The one-piece wear-resistant ceramic rods are assembled by firing the ceramic rods as a whole and pouring them into the steel sleeve with special fillers. The ceramic rod has a smooth inner wall, good airtightness, and good wear resistance and corrosion resistance. However, this kind of product has a long production cycle and high cost.
 
The composite rod has fully utilized the metal rod's high strength, good toughness, impact resistance, good welding performance and the high hardness, high wear resistance, corrosion resistance and heat resistance of the corundum porcelain, which overcomes the low hardness of the metal rod, poor wear resistance and ceramics. Characteristics of poor toughness. Therefore, the composite rod has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical and thermal shock resistance, and good weldability.
 
Because of its wear resistance, corrosion resistance and heat resistance, zirconia ceramic rods can be widely used in electric power, metallurgy, mining, coal, chemical and other industries as corrosive media. It is an ideal wear-resistant ceramic rod.
