Abstract: This paper deals with the influence of metal and alloy on the measurement of wetting angle of microdot artificial diamond by means of microscopy and scanning electron microscopy. The influence of noncarbide forming elements of untransition group (Cu, Sn, Pb, Al, Ag) and Cu-Sn alloy on the wetting ability of microdot artificial diamond is also studied.In addition to this, the influence of adding carbide forming element of tra-nsition group Ti on the wetting angle is also discussed.lt is shown that the wetting angle decreases with the increase of large amount of Ti.
