Do you know what the preparation method of boron nitride coating is? Follow the editor of Metal based boron nitride coating for casting factory to have a simple understanding!

A method for preparing a hexagonal boron nitride coating on the surface of a carbon fiber material. The method is as follows: first pretreating the surface of the carbon fiber material, and then using a mixture of molten boric acid and urea as a liquid precursor, boric acid and Urea is the boron source and nitrogen source of hexagonal boron nitride. The carbon fiber material after surface pretreatment is immersed in a liquid precursor and supercooled to crystallize, and then heat treated in a nitrogen atmosphere furnace to obtain a hexagonal boron nitride coating on the surface. Layer of carbon fiber. The hexagonal boron nitride coating prepared on the surface of the carbon fiber material of the present invention does not affect the strength and toughness of the carbon fiber material. The method has the advantages of simple process, low cost, dense coating, and reliable bonding, and It is suitable for carbon fiber tow, carbon cloth and fiber preform, etc., and has significant application potential in engineering practice.
The above is the editor of Metal based boron nitride coating for casting factory: a brief introduction to the relevant knowledge of the preparation method of boron nitride coating.
