Molybdenum Powder [-325+400]

Understanding Molybdenum Powder [-325+400]

This powder is defined by its specific mesh cut of -325+400, meaning particles pass through a 325-mesh screen but are retained on a 400-mesh screen. This tight particle size distribution is essential for achieving a stable powder flow from the feeder through the thermal spray gun and into the flame or plasma jet. Inconsistent particle sizes can lead to spitting, uneven coating thickness, and poor deposit efficiency.

Molybdenum coatings are valued for their high melting point, excellent bond strength to many ferrous and non-ferrous substrates, and natural lubricity. Common applications include coating piston rings, synchronizer rings, gear shift forks, and other automotive or industrial parts subject to sliding wear and fretting. The coating provides a hard, scuff-resistant surface that can operate effectively even under boundary lubrication conditions.

Thermal Spray Process Compatibility

Selecting the right powder for your equipment is critical. Molybdenum Powder [-325+400] is compatible with several common thermal spray processes, but the optimal choice depends on your specific application, part geometry, and desired coating properties.

• Plasma Spray: Often the preferred method for applying molybdenum, as the inert atmosphere minimizes oxidation and produces dense, well-bonded coatings.
• HVOF (High-Velocity Oxygen Fuel): Produces extremely dense coatings with high bond strength, ideal for applications requiring maximum wear resistance.
• Flame Spray: A cost-effective method suitable for less critical applications or field repairs, using oxygen and acetylene.

We recommend discussing your specific gun model and process parameters with our team to confirm the ideal powder grade for your setup.

Pack Sizes and Handling

SPA2Z supplies this Molybdenum Powder in standard pack sizes designed for industrial use and safe handling. Proper storage is essential to maintain powder quality and prevent contamination.

• 5 kg Tin: Ideal for initial testing, small-batch production, or R&D purposes.
• 10 kg Tin: A convenient mid-range option for regular maintenance and repair operations.
• 25 kg Pail: The most economical choice for high-volume production environments.

Store powder in its original, sealed container in a cool, dry environment away from sources of ignition. Avoid exposure to moisture, which can cause agglomeration and affect flowability.
