Tungsten tetraboride composite matrix and uses thereof

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.

1 . A composite matrix comprising:
 a) a first formula (W 1-x M x X y ) n  
 wherein:
 X is one of B, Be and 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), yttrium (Y) and aluminum (Al); 
 x is from 0.001 to 0.999; 
 y is at least 4.0; and 
 n is from 0.01 to 0.99; 
 
   b) a tungsten carbide of formula (WC 0.99-1.05 ) p , wherein p is from 0.01 to 0.99; and   c) a second formula T q ;
 wherein:
 T is an alloy comprising at least one Group 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14 element in a Periodic Table of Elements; and 
 q is from 0.01 to 0.99; and 
 
 wherein p, q, and n have a sum of 1.
