Self-Fluxing and Self-Fusing Alloys for Dense Coatings

Self-fluxing Materials

Self-fluxing materials are first applied using a thermal spray process, such as

• Combustion Powder Thermospray™
• Atmospheric Plasma Spray
• High Velocity Oxygen Fuel (HVOF) spray

While the coatings can be used "as-sprayed," post-coat fusing is recommended to coalesce the coating, thereby making it fully dense and with optimal surface properties.

Characteristics and Benefits of Fused Coatings

• Fully dense-coating microstructure
• High coating hardness
• Excellent wear and corrosion resistance
• Coatings are metallurgically bonded to the substrate
• Coatings can be ground to tight dimensions with a good finish

Self-fusing Materials

For situations when post-coat fusing may distort the component or the substrate cannot tolerate the heat of the fusing process, self-fusing materials are a good alternative. These materials partially coalesce during the spray process without requiring a post-coat fusing.

Characteristics and Benefits of Self-fusing Materials

• Easy to use, one-step coating process
• Very low porosity
• Very good coating hardness
• Very good wear and corrosion resistance
• Bonds well to the substrate
• Coatings can be ground to tight dimensions with a good finish

Flexibility to Suit Your Production Needs

In many cases, the coatings are easily applied using a simple combustion powder Thermospray™ system. Fusing, when required, is often accomplished manually using a simple oxy-acetylene torch.

For higher production volumes or mass production, a fully automated system can be used to apply the coatings. Fusing can be batch-processed in furnaces or accomplished using Radio Frequency (RF) induction coils. When done properly, part distortion is negligible to non-existent.

We offer a range of self-fluxing and self-fusing alloys to suit various application requirements. For the highest wear resistance, we supply products with carbide hard phases.
