Molybdenum Powder 20-63 µm

Understanding Molybdenum Powder for Thermal Spray

Molybdenum-based coatings are valued for their unique combination of high melting point, excellent bond strength to steel substrates, and outstanding resistance to adhesive wear and scuffing. The 20-63 µm particle size range is a widely accepted standard in the thermal spray industry, offering a balance between flowability and melt characteristics that suits a variety of spray equipment.

This powder is typically sprayed onto components that operate under high mechanical loads and in boundary lubrication conditions. The coating's natural porosity can also aid in oil retention, further enhancing its performance in tribological applications. Selecting the correct powder grade and particle size is critical to achieving the desired coating density, hardness, and surface finish.

Key Features and Benefits

• Controlled Particle Size (20-63 µm): Ensures consistent powder feeding and uniform melting for reproducible coating quality across production batches.
• Scuff and Wear Resistance: Delivers coatings that significantly reduce adhesive wear on mating surfaces, a critical requirement for automotive and hydraulic components.
• High Bond Strength: Forms a strong mechanical bond to properly prepared steel and alloy substrates, minimizing the risk of delamination.
• Process Versatility: Suitable for use with HVOF, plasma, and flame spray equipment, providing flexibility in your coating workshop.
• Industrial Pack Sizes: Available in 5 kg tins, 10 kg tins, and 25 kg pails to match your project scale, from R&D trials to full production runs.

Typical Applications

The wear-resistant properties of molybdenum coatings make this powder a go-to choice for a range of precision engineering components. Common applications include:

• Automotive Components: Piston rings, synchronizer rings, gear shift forks, and thrust washers where scuff resistance is paramount.
• Industrial Machinery: Pump shafts, compressor rods, and bearing journals that require enhanced surface durability.
• Aerospace: Selective coating of turbine and engine components for wear protection in non-oxidizing environments.
• General Engineering: Salvage and dimensional restoration of worn steel parts, followed by finishing to original specifications.

Selection and Handling Guidance

To achieve optimal coating results, the powder must be kept dry and free from contamination. Store containers in a cool, dry environment and reseal them promptly after use. The powder's flow characteristics are optimized for standard thermal spray feeders; however, we recommend conducting a spray trial with your specific equipment setup to fine-tune parameters like feed rate, carrier gas flow, and spray distance. Our team can provide technical guidance to support your parameter development.
