Wetting of diamond and graphite by liquid iron-titanium alloys

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    The ability of liquid iron and iron-titanium alloys to wet diamond is greater for the (100) face than for the natural (111) face. Pyrographite occupies an intermediate position.

  2. 2.

    The wetting of diamond and graphite by iron is improved by the addition of more than 30% titanium to the latter.

  3. 3.

    The angle of contact of pure iron on pyrographite is 50° and that of an iron-3.9% C alloy on pyrographite, about 110°.

  4. 4.

    The work of adhesion of iron to the (100) and (111) faces of diamond is 3160 and 2590 ergs/cm2, respectively, while the work of adhesion of iron to pyrographite is 2960 ergs/cm2. Titanium increases the work of adhesion of iron to graphite and diamond.
