Features of Factory supply tungsten carbide powder, WC Co powder clear powder coating hvof spray
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of Factory supply tungsten carbide powder, WC Co powder clear powder coating hvof spray
Tungsten carbide (WC) is a high-performance material known for its exceptional hardness, wear resistance, and thermal stability. As a leading supplier of tungsten carbide powders, we offer a wide range of products that cater to various industrial applications, including cutting tools, wear-resistant coatings, and precision engineering.
Our WC powders, specifically the WC-Co (tungsten carbide with cobalt binder) variety, are carefully formulated to ensure optimal performance in harsh environments. The WC Co powder we supply comes in different grades, depending on the desired properties such as particle size distribution, purity, and cobalt content. This allows customers to select the most suitable grade for their specific manufacturing needs.
The clear powder coating process, often used in High-Voltage Oxygen Fuel Spray (HVOF) technology, is an advanced method of applying the tungsten carbide powder to create a durable, wear-resistant surface. HVOF spraying involves the combustion of a fuel-air mixture, which propels the powder particles at high velocities towards the substrate. This results in a dense, adherent coating with excellent bond strength and minimal porosity.
The HVOF spray parameters we provide are meticulously optimized to achieve consistent coating quality and thickness. Key parameters include:
1. Powder feed rate: Adjusted to ensure a uniform layer buildup while maintaining the desired coating thickness.
2. Temperature: The temperature of the fuel-air mixture determines the melting point of the binder, affecting the coating’s adhesion and hardness.
3. Pressure: The pressure ensures the powder is atomized effectively, enhancing the coating’s density and minimizing defects.
4. Spraying distance: Maintaining an optimal distance between the gun and the substrate helps control the coating’s thickness and uniformity.
5. Gas flow rate: The balance of oxygen and fuel gases controls the energy transfer to the powder and affects the coating’s properties.
6. Particle velocity: The speed at which the powder particles leave the spray nozzle impacts the coating’s density and bonding strength.
In our manufacturing process, we adhere to strict quality control measures to ensure the powder’s particle size distribution meets industry standards. We also conduct regular tests to monitor the coating’s microstructure, hardness, and wear resistance after HVOF application.
In summary, our tungsten carbide powders, combined with the HVOF spray technique, offer a reliable solution for enhancing the performance and longevity of components across various industries. Our expertise in formulating and applying these powders ensures that our customers receive high-quality coatings tailored to their specific requirements. If you need more detailed information or assistance with selecting the right powder and spray parameters, please don’t hesitate to contact us.
