Metallization and characteristics of zirconia ceramic rods
The zirconia ceramic rod is processed by isostatic pressing process to form a uniform, dense and smooth surface ceramic layer and transition layer at high temperature and high speed. Because of its advanced manufacturing process and high cost, it is suitable for precision ceramic parts, and its wear resistance is stronger than other ceramic rods. It is generally used as a high wear-resistant place.
The metallization of the zirconia ceramic rod is to adhere the ceramic rod to the inner wall of the metal with a high temperature resistant strong adhesive, and after curing by heating, a firm anti-wear layer is formed. The production process of the 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 essentially unrestricted in size and can be produced from 0.5 mm to 160 mm in diameter and even larger.
The ceramic rod is punched with a high-temperature resistant adhesive to adhere the ceramic rod with a hole in the inner wall of the metal, and the ceramic is firmly welded to the inner wall of the steel sleeve through the small hole in accordance with the spot welding process. To protect the solder joint, screw the ceramic cap on top. Each porcelain rod not only abuts each other, but each of them forms a corresponding angle, so that the porcelain rods are tightly connected without gaps; when the last one of the rings is closely embedded, a mechanical self-locking of 360 is formed between the ceramic rods. force. The production process of the product is relatively complicated, the production cycle is long, and the cost is high.
The integrally formed wear-resistant ceramic rod is assembled by integrally molding the ceramic rod member and pouring it into the steel sleeve with a special filler. The ceramic rod has a smooth inner wall, good sealing and sealing performance, and has good wear resistance and corrosion resistance. However, this product has a long production cycle and high cost.
The composite rod has fully exerted the high strength, good toughness, impact resistance, good welding performance and high hardness, high wear resistance, corrosion resistance and heat resistance of the metal rod, which overcomes the low hardness of the metal rod, poor wear resistance and ceramics. Poor toughness. Therefore, the composite rod has good comprehensive properties such as good wear resistance, heat resistance, corrosion resistance, mechanical shock resistance, thermal shock resistance and weldability.
Because zirconia ceramic rods have wear resistance, corrosion resistance and heat resistance, they can be widely used as corrosive media in electric power, metallurgy, mining, coal, chemical and other industries. It is an ideal wear-resistant ceramic rod.
