摘要：

TiB2 among other borides like ZrB2 and HfB2 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 TiB2 by Cu and Au (50A degrees and 15A degrees, 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 TiB2 but also the chemical interaction stands behind good wetting in these systems.
