Applications of boron nitride coatings

With the continuous improvement of aluminum alloy casting technology, the quality of aluminum alloy products has also been continuously improved. Among them, coatings play a crucial role. They form a protective layer on the surface of casting tools, improving the corrosion resistance of casting tools, reducing or even avoiding contact between the alloy liquid and the casting tools, thereby 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.
