Boron diffusion coating

WebBN High Purity is a relatively-soft, washcoat-type of Boron Nitirde (BN) coating that provides high-purity (over 99% pure) BN after firing. The coating is usable in vacuum to 1400 C (2552 F) and inert atmospheres to 1800 C (3272 F). This coating should NOT be used in air atmospheres. WebApr 12, 2024 · According to the Arrhenius diffusion law , the surface diffusion rate of the thin Ag-Ge alloy film at 280°C is 15.49 times of that at 120°C. After 350 hours of accelerated aging test at 280°C (corresponding to 5422 hours at the operating temperature of the PRILD), the degradation in the luminous efficacy is negligible ( Fig. 4E and fig. S17).
