Applications of boron nitride coatings

　　As aluminum alloy casting technology continues to improve, the quality of aluminum alloy products is also constantly improving. Coatings play a crucial role, forming a protective layer on the surface of casting tools, improving the corrosion resistance of the casting tools, reducing or even avoiding contact between the alloy liquid and the casting tools, thus effectively avoiding the corrosion of the casting tools by the alloy liquid and the contamination of the alloy liquid by the casting tools, improving the quality of castings, and ensuring the performance of the aluminum alloy.

　　Application of Boron Nitride Coating

　　1. Boron nitride coating is an inert inorganic high-temperature lubricating material. It is non-sticky and does not penetrate into molten metal liquid. It can completely protect the surface of refractory materials or ceramic containers that are in direct contact with molten aluminum, magnesium, zinc alloys and slag, playing a role in high-temperature resistance, anti-adhesion, and anti-oxidation, thereby improving casting efficiency, reducing the defect rate, and extending the service life of the mold. In addition, boron nitride coating can also be used in the smelting and casting process of aluminum alloys to protect the metal surface and prevent oxidation and corrosion, while also improving the wear resistance and fatigue resistance of the aluminum alloy.

　　2. Boron nitride coatings are widely applied to the surfaces of casting runners, distribution runners, transfer plates, sleeves, degassing equipment linings, filter boxes, casting nozzles, slag spreaders, and ladles, protecting molds, resisting corrosion and extending the service life of refractory materials. At the same time, during production, it prevents fine impurities from penetrating into the aluminum liquid, causing secondary pollution, and greatly improving product quality.

　　3. It is the preferred choice for customers with higher melting and casting requirements or higher requirements for cast products, and it is a necessary product for the production of military-grade products.
