The Nautilus Lubricant Removal System
The Abbott Furnace Nautilus System is an innovation designed for the production of Soft Magnetic Components. Years of research in the areas of lubricant removal and the formation of coherent oxide coatings in high-density components have been combined to provide an approach that enhances Soft Magnetic Component manufacturing. The Nautilus Lubricant System utilizes convective heating and independent atmosphere injection to provide optimal process environments.
The Abbott Furnace Nautilus delube technology is the latest development in the production of soft magnetic composites. The Nautilus produces an insulating oxide coating on each particle of the soft magnetic compact; while imparting strength to the compact. This technology eliminates the costly need to sinter at high temperatures and high hydrogen levels. The result is a composite with unique and improved soft magnetic properties.
The Nautilus Lubricant Removal System is another Abbott Furnace innovation that is driving improved performance and cost efficiencies.
Keys to a Successful Soft Magnetic Composite
- High-Density Compaction to Reduce Porosity
- Particle Surfaces are Clean Prior to Forming the Coating Coherent
- Insulating Coating
Lubricant Removal is Critical to the prevention of the loss of magnetic performance. The coherent oxide provides an insulation layer around each particle to improve properties.
Lubricant is required for the compaction of the powder metal component; however, if all of the lubricant is not removed prior to applying the oxide coating, carbon soot from the lubricant will contaminate the oxide coating and negatively effect the magnetic properties of the final component.
