Abstract

The sessile-drop technique has been used to investigate the wetting in vacuo by a series of intermetallic compounds (TiAl3, TiSi2, TiNi, TiNi3, TiCr2, Cr3Si2, Fe2Al5, FeSi, Fe2Si5, CoSi, “CoSi3”, Ni3Al, Ni2Si), by silicon and by a nickel alloy (713LC), of single-crystal Al2O3, single-crystal SiC, polycrystalline Si3N4, pyrolytic BN, and in some cases only, tungsten. Measurements of contact angle were made at fixed temperatures within the range 1200 to 1600‡C. Qualitative observations were made of the interaction and degree of bonding between the constituents. The results of the various experiments are compared and contrasted.
