Abstract

TiB ₂ among other borides like ZrB ₂ and HfB ₂ represents a unique class of ceramics, which displays good wetting by liquid metals, such as Cu and Au, without chemical interaction that may be detected by conventional characterization techniques. The nature of the wetting in these systems is commonly attributed to the "metallic-like" character of borides. In this study, improved wetting of TiB ₂ by Cu and Au (50° and 15°, respectively) was confirmed and evidence of a limited chemical interface interaction was observed using TEM analysis. Moreover, it was shown that the addition of B to Au and Cu improves wetting. It was suggested that not only "metallic-like" character of TiB ₂ but also the chemical interaction stands behind good wetting in these systems.
