Nickel-Aluminum Powder [-325+400]

Thermal Spray Bond Coat Powder

This Nickel-Aluminum composite powder is engineered for use as a bond coat in thermal spray processes. When sprayed through HVOF, plasma, or flame equipment, the nickel-aluminum reaction generates high localized temperatures, promoting metallurgical bonding to the substrate. The resulting coating provides an excellent roughened surface profile that mechanically locks subsequent ceramic or metallic top coats in place.

The -325+400 mesh cut (approximately 38–44 microns) offers a controlled particle size distribution suitable for consistent powder feeding and uniform melting in the spray stream. Buyers typically select this grade for applications requiring a thin, uniform bond layer before applying wear-resistant or corrosion-resistant top coats.

Typical Applications

Procurement professionals and workshop managers source this powder for:

• Bond coats before ceramic top coats on industrial components.
• Dimensional restoration of worn shafts, journals, and bearing housings.
• Oxidation and corrosion protection at elevated temperatures.
• General maintenance and repair in foundries, fabrication workshops, and engineering plants.

Selection and Handling

When selecting a Nickel-Aluminum powder, confirm compatibility with your thermal spray equipment and the specific grade required for your application. Store powder containers in a cool, dry environment and keep sealed when not in use to prevent moisture absorption, which can affect flowability and spray characteristics. Always consult your equipment manufacturer's guidelines for optimal parameter settings.
