FAQs

What are plasma quality powders used for?

Plasma quality powders are used in a variety of applications, including additive manufacturing, thermal spray coatings, biomedical implants, aerospace components, automotive parts, energy sector components, tooling, electronic devices, defense applications, and even jewelry.

What is plasma quality powder?

Plasma quality powder is a specific type of metal or ceramic powder used in thermal spraying. Thermal spraying is a process that uses a plasma torch to melt and spray these powders onto a surface, creating a coating with desired properties like wear resistance, corrosion resistance, or thermal insulation.

What makes a good plasma quality powder?

Several factors contribute to a high-quality thermal spray powder:

• Chemistry: The powder’s exact composition plays a crucial role in the final coating’s properties. Manufacturers may offer powders with specific chemistries depending on the application.
• Particle size and distribution: Consistent particle size and distribution ensure proper melting, deposition efficiency, and coating quality.
• Particle shape: The shape of the powder particles can influence the flowability, packing density, and splat morphology (shape of the deposited material) in the coating.
• Flowability: Powders need to flow freely for proper feeding into the thermal spray equipment.

How does plasma quality powder differ from other types of metal powders?

Plasma quality powders are often finer and more precisely sized compared to welding powders or powders for additive manufacturing. They might also have tighter chemistry control to achieve specific properties in the final coating.

Where can I find information on specific plasma quality powders?

Reputable powder manufacturers typically provide detailed data sheets for their products. These data sheets will include information on the powder’s chemistry, particle size distribution, morphology, and other relevant specifications.

What are some factors to consider when choosing a plasma quality powder?

• Desired coating properties: What properties do you need the coating to have (e.g., wear resistance, corrosion resistance, thermal conductivity)?
• Substrate material: The type of material being coated will influence compatible powder selection.
• Thermal spray process: Different thermal spray processes may require powders with specific characteristics.
• Cost: Plasma quality powders can vary in price depending on the material, chemistry, and production method.
