A blended powder of tungsten carbide and Metal Alloy Powder can be used for laser cladding, a process used to deposit a layer of material onto a substrate using a laser beam. This blended powder is typically used as a feedstock material for laser cladding applications where high wear resistance and hardness are required.

Top entry ball valve is particularly applicable for such industries as petroleum, chemical engineering and nuclear power plants. Its body adopts an integrated design, thus reducing leak points. Its seat design is available for either soft or hard seal, easy for maintenance. With its advanced manufacturing process and reasonable structure design, it can bear high temperature and high pressure, so it has a wide application scope. Â
Design characteristics of product:Â Â
1. It's featured by its integrated body design, top entry trunnion fixing support and flange or butt welding structureÂ
2. The Inco nickel corrugated spring drives the enclosed metal seat to move towards the ball, with the two-way seal function for its inlet and outletÂ
3. It adopts the unique retractable seat technology, and also is available for online replacement of ball rod, stem gasket ring, metal seat and corrugated spring, with minimized torque for its easy operationÂ
4. It's easy for maintenance and installation and has a long service life. Its internal components are available for maintenance and replacement without unloading it from the pipeline, thus extending its service lifeÂ
5. It's featured by its small torque and reliable seal; and unlike common ball valve types, its seat with a spheroidal structure can adjust the seal position automaticallyÂ
6. It's preset with an actuator platform and bolt holes, and conforms to requirements by ISO5211. The actuator is ready to be assembled any time in accordance with different requirements of usersÂ
7. The valve is provided with double block and bleed function (DBB)Â
8. The manual top entry ball valve adopts a high-strength integrated ball rod structure, ensuring the ball's accurate positionÂ
9. Its stem adopts a blowout-proof protection structure, making its operation safely.

Tungsten carbide is a hard and wear-resistant material that is commonly used in cutting tools, mining equipment, and other high-wear applications. It has excellent thermal conductivity and high melting point, making it suitable for laser cladding processes.
Metal alloy powders, on the other hand, are often added to the Tungsten Carbide Powder to enhance certain properties or tailor the characteristics of the final cladding layer. These metal alloys can include nickel, cobalt, chromium, or other elements, depending on the specific requirements of the application.
The blended powder is typically prepared by mixing the tungsten carbide and metal alloy powders in the desired ratio. This mixture is then fed into a laser cladding system, where it is melted using a high-power laser beam. The molten powder is rapidly solidified onto the substrate, forming a dense and wear-resistant cladding layer.
The resulting cladding layer can have excellent hardness, wear resistance, and thermal conductivity, making it suitable for various applications such as tooling, wear parts, and surface protection. The specific properties of the cladding layer can be adjusted by varying the composition and ratio of the tungsten carbide and metal alloy powders in the blend.
Overall, the blended powder of tungsten carbide and metal alloy powder offers a versatile and customizable solution for laser cladding applications, providing enhanced wear resistance, hardness, and other desired properties to the final cladding layer.
