Title:
ADVANCED EROSION RESISTANT CARBIDE CERMETS WITH SUPERIOR HIGH TEMPERATURE CORROSION RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2004/104249
Kind Code:
A2
Abstract:
Cermets are provided in which a substantially stoichiometric metal carbide ceramic phase along with a reprecipitated metal carbide phase, represented by the formula MXCY, is dispersed in a metal binder phase. In MxCy M is Cr, Fe, Ni, Co, Si, Ti, Zr, Hf, V, Nb, Ta, Mo or mixtures thereof, x and y are whole or fractional numerical values with x ranging from 1 to 30 and y from 1 to 6. These cermets are particularly useful in protecting surfaces from erosion and corrosion at high temperatures.
