Types and characteristics of metallization of zirconia ceramic rod
Zirconia ceramic rod is produced by isostatic pressing process, forming uniform, dense and smooth ceramic layer and transition layer at high temperature and high speed.Because of advanced technology and high cost, it is suitable for precision ceramic parts, and its wear resistance is stronger than other ceramic rods, so it is generally used for high wear resistance.
Zirconia ceramic bar metallization is the use of high temperature resistant adhesive ceramic stick in the inner wall of the metal, after curing by heating formed a firm anti - wear layer.This product production process is relatively simple, the production cycle is short, 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 largely free of size restrictions, ranging in diameter from 0.5mm to 160mm, or more.
Ceramic rod punching is the use of high temperature resistant adhesive will be stuck in the middle of the ceramic rod with holes in the inner wall of the metal, at the same time with the spot welding process through the small hole will be firmly welded in the inner wall of the steel sleeve.To protect the solder joint, the ceramic cap is rotated on top.Each porcelain rod is not only close to each other, but also forms a corresponding Angle, so that the porcelain rod is closely connected, seamless;When the last piece of the circle is tightly embedded, a mechanical self-locking force of 360 is formed between the porcelain bars.The production process of this product is relatively complicated, the production cycle is longer, the cost is higher.
The wear-resistant ceramic bar is made by firing the ceramic bar as a whole and then pouring it into the inner assembly of the steel case with special filling materials.The ceramic rod has smooth inner wall, good sealing, good wear resistance and corrosion resistance.But the production cycle is long and the cost is high.
The composite rod gives full play to the characteristics of high strength, good toughness, impact resistance, good welding performance, high hardness, high wear resistance, corrosion resistance and heat resistance of corundum porcelain, overcoming the characteristics of low hardness, poor wear resistance of metal rod and poor toughness of ceramics.Therefore, the composite rod has good wear resistance, heat resistance, corrosion resistance, mechanical impact and thermal impact resistance, good weldability and other comprehensive properties.
Zirconium oxide ceramic bar has the properties of abrasion resistance, corrosion resistance and heat resistance, so it can be widely used in electric power, metallurgy, mining, coal, chemical industry and other industries as corrosive medium, is an ideal abrasion resistance ceramic bar.
