Key Characteristics of Surface coating specialist Agglomerated and Sintered/Tungsten Metal Powder/Thermal Spray WC Powder Hard surface material
-
Particle Size and Distribution: The size and uniformity of particles significantly influence flowability, packing density, and the final product’s mechanical and physical properties. Finer powders generally offer a larger surface area, which is beneficial for reactions and sintering but may also increase aggregation.
-
Composition: Metal powders can be elemental (pure metal) or alloyed, combining two or more metals to achieve desired properties such as enhanced strength, corrosion resistance, or electrical conductivity.
-
Shape: Particle shapes range from spherical to irregular or flake-like. Spherical powders provide better flowability and packing, while flake-shaped powders are suited for coatings and electronic applications due to their unique orientation and surface area.
-
Purity: Depending on the application, metal powders can be highly purified to remove impurities, critical for uses in electronics, aerospace, and medical devices where contamination could compromise performance.

Parameters of Surface coating specialist Agglomerated and Sintered/Tungsten Metal Powder/Thermal Spray WC Powder Hard surface material
The parameter you’re referring to likely pertains to the properties of a tungsten carbide (WC) powder used in surface coatings, specifically for thermal spray applications. Tungsten carbide is a popular choice due to its high hardness, wear resistance, and excellent thermal stability. Here’s a list of key parameters for a typical tungsten carbide thermal spray WC powder:
1. Particle Size Distribution: This refers to the range of particle sizes present in the powder mixture. It affects the coating’s density, porosity, and adherence to the substrate.
2. Shape and Morphology: Powders can be spherical, irregular, or a combination, which influences the coating’s texture and bonding strength.
3. Purity: The percentage of tungsten carbide (WC) in the powder should be close to 99% to ensure maximum performance.
4. Coating Adhesion: Measured as the bond strength between the sprayed coating and the substrate. Higher adhesion ensures better durability.
5. Hardness: Vickers hardness (HV) or Brinell hardness (HB) values indicate the resistance to indentation. WC coatings typically have a hardness in the range of 2000-3500 HV.
6. Wear Resistance: A measure of how well the coating resists abrasive wear under various conditions.
7. Thermal Conductivity: Essential for heat dissipation during high-temperature applications, typically lower than that of bulk tungsten carbide.
8. Coefficient of Thermal Expansion (CTE): Determines how much the coating expands or contracts with temperature changes, important for maintaining dimensional stability.
9. Density: The mass per unit volume of the powder, affecting the coating’s porosity and overall performance.
10. Melting Point: Tungsten carbide melts at around 3422°C (6292°F), ensuring it can withstand high temperatures during thermal spraying.
11. Chemical Stability: Resistance to corrosion and oxidation, which can affect the coating’s lifespan.
12. Coating Thickness: Dependent on application requirements, but typically in micrometers (μm) or millimeters (mm).
These parameters are subject to change based on the specific manufacturer’s formulation and the intended application. Always consult the product data sheet for detailed information.
