Boron nitride coatings are utilized during the melting and casting of aluminum alloys to protect metal surfaces and prevent oxidation and corrosion; simultaneously, they enhance the wear resistance and fatigue strength of the aluminum alloys.
These coatings are widely applied to the surfaces of casting launders, distribution troughs, transfer plates, sleeves, degasser linings, filter boxes, casting nozzles, skimmers, ladles, and similar components. By protecting the molds and providing corrosion resistance, they effectively extend the service life of refractory materials. Furthermore, during the production process, they prevent the infiltration of minute impurities into the molten aluminum—thereby averting secondary contamination—and significantly improve overall product quality.
This solution is the preferred choice for clients with stringent requirements regarding melting and casting processes or the quality of their cast products; it is considered an essential requirement for the production of military-grade materials.
