LRA- 15 boron nitride (also known as LRRA- 15 boron nitride high temperature resistant lubrication isolation coating)
Performance: it can resist ultra-high temperature, maintain excellent lubrication performance at high temperature, is non-toxic and pollution-free, highly environmentally friendly, chemically inert, extremely low friction coefficient, high pressure resistance, high resistance, thermal shock resistance, corrosion resistance and good thermal conductivity.
The hardness of boron nitride can be said to be very high, and it is usually used as composite ceramics, or as advanced refractories and superhard materials.
