The wettability of silicon carbide by liquid aluminium : the effect of free silicon in the carbide and of magnesium, silicon and copper alloy additions to the aluminium

Results from sessile drop method are reported for effects on wetting angle of free Si in SiC substrate and of alloy additions of Si, Cu, or Mg to Al drop at 700-960 degrees C or 1040 degrees in a Ti-gettered vacuum (10 sup - sup 4 /10 sup - sup 5 torr). Wetting angle is reduced by a factor as large...

Zusammenfassung:	Results from sessile drop method are reported for effects on wetting angle of free Si in SiC substrate and of alloy additions of Si, Cu, or Mg to Al drop at 700-960 degrees C or 1040 degrees in a Ti-gettered vacuum (10 sup - sup 4 /10 sup - sup 5 torr). Wetting angle is reduced by a factor as large as 2.8 for pure Al on reaction-bonded, as compared with sintered, SiC. 49 refs.
