Self-Flux / Fusing Alloy Powder
Self-fluxing materials
Self-fluxing materials are first applied using a thermal spray process, such as combustion powder Thermospray, atmospheric plasma spray, or High Velocity Oxygen Fuel (HVOF) spray. While the coatings can be used “as-sprayed,” post-coat fusing is recommended to coalesce the coating.
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
