Effect of temperature and surface roughness on the wettability of boron nitride by molten Al

Abstract

Reactive wetting of hexagonal BN by molten Al at 1073-1273 K was studied using an improved sessile drop method. The temperature and substrate surface roughness have a remarkable effect on the wetting behavior. Reasons for the large discrepancy in the final contact angles reported in the literature were addressed. © Springer Science+Business Media, LLC 2007.
