Abstract:

The validity of the sessile drop method was examined to determine the wettability of the SiC fibre which has a finite curvature and contact angles of liquid pure Cu, Sn and Ag were measured on 2 types of SiC fibres.
Main results are as follows:
(1)  The sessile drop method is applicable to measure the contact angle of liquid metal on SiC fibre which has a finite curvature.
(2)  Liquid pure metal (Cu, Sn and Ag)/SiC fibre systems are non-wetting ones.
(3)  The results obtained are comparable with the previous work for SiC substrate.
