Ceramic Zirconia Powder 20-63 µm

Zirconia Powder for Thermal Barrier and Wear-Resistant Coatings

Zirconia (zirconium dioxide) powders are a cornerstone of advanced thermal spray technology, valued for their exceptional high-temperature stability, low thermal conductivity, and resistance to thermal shock. The 20-63 µm particle size distribution is a common and effective cut for achieving consistent powder flow and optimal melting in a range of thermal spray equipment.

This powder is typically applied to components in aerospace, power generation, and heavy industrial sectors where surfaces must withstand extreme operating conditions. The resulting ceramic coating provides a durable thermal barrier, protects against hot gas corrosion, and can significantly extend the service life of expensive parts.

Process Compatibility and Application Guidance

Selecting the correct powder grade and spray parameters is critical for coating success. This powder is physically suitable for the following processes, with final suitability confirmed based on your specific equipment and application requirements:

• HVOF (High-Velocity Oxy-Fuel): Produces very dense, well-bonded coatings with high hardness, ideal for wear and corrosion protection.
• Plasma Spray: The most common method for applying zirconia thermal barrier coatings (TBCs), allowing for excellent control over coating microstructure and thickness.
• Flame Spray: A cost-effective option for less demanding applications where a porous, insulative coating is acceptable.

We recommend discussing your specific substrate material, desired coating thickness, and operating environment with our team. This ensures the powder grade and process recommendation are perfectly matched to your technical goals.
