Spherical tungsten carbide powder is an important industrial raw material, which has a wide range of uses, mainly in cemented carbide, ceramics, spraying and other fields. This article will introduce the uses of spherical tungsten carbide powder in detail.
1. Preparation of cemented carbide.
Spherical tungsten carbide powder is one of the main raw materials for the preparation of cemented carbide. In the process of cemented carbide preparation, spherical tungsten carbide powder is mixed with metal powders such as cobalt, and after pressing, sintering and other processes, cemented carbide with the advantages of high hardness, high strength and wear resistance can be obtained. The particle size and particle size distribution of spherical tungsten carbide powder have an important impact on the properties of cemented carbide, so strict quality control is required during the preparation process.
2. Preparation of ceramic materials.
Spherical tungsten carbide powder is also widely used in the preparation of ceramic materials. Spherical tungsten carbide powder is mixed with ceramic raw materials such as kaolin and alumina, and after molding, sintering and other processes, ceramic materials with the advantages of high strength, high hardness and wear resistance can be obtained. The addition of spherical tungsten carbide powder can significantly improve the mechanical properties and wear resistance of ceramic materials, so it has a wide application prospect in the field of ceramics.
3. Spraying field.
Spherical tungsten carbide powder is also widely used in the field of spraying. Due to its advantages of high hardness, high strength and wear resistance, it is widely used in metal surface spraying, repair and other fields. Spherical tungsten carbide powder is sprayed onto the metal surface by thermal spraying technology, which can significantly improve the wear resistance, corrosion resistance and fatigue resistance of the metal. In the fields of automobiles, aerospace, machinery, etc., spherical tungsten carbide powder has become one of the important surface treatment materials.
