For a fully dense coating that is highly wear and corrosion resistant, choose a self-fluxing alloy applied using a thermal spray process followed by a post-coat fuse. Self-fusing alloys offer many of the benefits of self-fluxing alloys when post-coat fusing is not feasible.
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
