Abstract:
1. A cermet composition represented by the formula (PQ)(RS) comprising: a ceramic phase (PQ) and a binder phase (RS) wherein, P is a metal selected from the group consisting of Al, Si, Mg, Ca, Y, Fe, Mn, Group IV, Group V, Group VI elements, and mixtures thereof, Q is oxide, R is a base metal selected from the group consisting of Fe, Ni Co, Mn and mixtures thereof, S consists essentially of at least one element selected from the group consisting of Cr, Al and Si and at least one reactive wetting element selected from the group consisting of Ti, Zr, Hf, Ta, Sc, Y, La, and Ce, and wherein the ceramic phase (PQ) ranges from of about 55 to 95 vol % based on the volume of the cermet and is dispersed in the binder phase (RS) in a closely packed arrangement wherein about 54 vol % of the ceramic phase (PQ) is between about 707 microns and about 7097 microns in diameter and about 46% of the ceramic phase (PQ) is between about 20 microns and about 707 microns in diameter.
