• The wettability of graphite and single crystal of α-SiC by liquid Cu-Cr alloy was investigated using the sessile drop method and the vertical plate method which was developed in this work.Main results are as follows;(1) The vertical plate method was proved to be applicable for the wetting system whose contact angle is acute.(2) The wettability of graphite by liquid Cu-Cr alloy dramatically changed at c.a. 0.3mass%Cr.(3) Electron probe microanalysis of the Cu-Cr alloy and graphite system revealed that Cr had concentrated at the interface.(4) Contact angles between liquid Cu-Cr alloys and single crystal of α-SiC were 10° and 10-20° at 0.23mass%Cr and 0.75mass%Cr, respectively.
