Abstract

Disclosed herein, in certain embodiments, are composite materials, methods, tools and abrasive materials comprising a tungsten-based metal composition, a tungsten carbide, and an alloy. In some cases, the composite materials or matrix are resistant to oxidation.

First claim

1 .- 20 . (canceled)

21 . A tool or tool component, wherein the tool or tool component comprises a composite material, wherein the composite comprises:
(a) a first composition comprising a first formula

wherein:
W is tungsten (W);
X is one of boron (B), beryllium (Be) and silicon (Si);

M is at least one of titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), zirconium (Zr), niobium (Nb), molybdenum (Mo), ruthenium (Ru), hafnium (Hf), tantalum (Ta), rhenium (Re), osmium (Os), iridium (Ir), lithium (Li), scandium (Sc), yttrium (Y) or aluminum (Al);
x is from 0 to 0.999;

y is at least 4.0;
n is from 0.5 to 0.999; and

(b) a second composition comprising a second formula T q ,
wherein:
T comprises an alloy which is a combination of four or more group 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 transition metal elements in the Periodic Table of Elements;
q is from 0.001 to 0.5;
the sum of q and n is 1; and
q and n are weight percentages;

wherein the composite material has an average Vicker's hardness of about 10 to about 30 GPa as measured under a force of 9.8 N (1 kgf).

22 . The tool of claim 21 , wherein the composite material is the body or the tool or tool component.

23 . The tool of claim 21 , wherein the composite material is a surface of the tool or tool component.

24 . The tool of claim 21 , wherein the composite material coats the tool or tool component.

25 . The tool of claim 21 , wherein the tool or tool component comprises a wheel or grinding wheel.

26 . The tool of claim 21 , wherein the tool or tool component comprises a drilling tool.

27 . The tool of claim 21 , wherein the tool or tool component comprises drill bits, inserts or dies.

28 . The tool of claim 21 , wherein the tool or tool component comprises a downhole tool.

29 . The tool of claim 21 , wherein the tool or tool component comprises an etching tool.

30 . The tool of claim 21 , wherein the tool or tool component comprises an engraving tool or carving tool.

31 . The tool of claim 21 , wherein the tool or tool component comprises a grinding tool or polishing tool.

32 . The tool of claim 21 , wherein the (W 1-x M x X y ) n has a median particle size of about 1 μm to about 750 μm.

33 . The tool of claim 21 , wherein the T q has a median particle size of about 45 μm or less.

34 . The tool of claim 21 , wherein X is B.

35 . The tool of claim 21 , wherein M comprises at least one of Re, Ta, Mn, Cr, Hf, Ta, Zr, or Y.

36 . The tool of claim 21 , wherein M comprises at least two of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Hf, Ta, Re, Os, Ir, Li, Sc, Y, or Al.

37 . The tool of claim 21 , wherein M comprises Re, Ta, Mn, or Cr.

38 . The tool of claim 21 , wherein x is from 0.001 to 0.4.

39 . The tool of claim 21 , wherein T comprises at least one of Co, Fe, Ni, or Sn.

40 . The tool of claim 21 , wherein the composite material is resistant to oxidation.
