Zirconia Powder for Thermal Spray Coatings
Zirconia-based ceramic coatings are a proven solution for thermal barrier and wear protection in challenging industrial environments. The -140+325 mesh particle size distribution is a common specification for thermal spray processes, offering a balance of flowability and melt characteristics required to produce consistent, high-quality coatings.
This powder is typically applied using High-Velocity Oxy-Fuel (HVOF), atmospheric plasma spray (APS), or flame spray systems. The resulting coatings exhibit excellent hardness, low thermal conductivity, and good resistance to thermal shock, making them suitable for protecting components in aerospace, power generation, and general engineering applications.
Selecting the Right Powder Grade
Successful coating performance depends on matching the powder chemistry and morphology to your specific process and application. Key variables include the stabilizer type (e.g., yttria-stabilized zirconia), the manufacturing route (which influences particle shape and density), and the precise particle size distribution within the mesh range.
We recommend discussing your process parameters and component requirements with our team. We can provide the relevant technical data sheet for the specific grade we supply and help you verify its suitability for your equipment and coating targets.
