Abstract:
1. A cermet composition represented by the formula (PQ)(RS)X comprising: a ceramic phase (PQ), a binder phase (RS) wherein the binder phase (RS) comprises a base metal R selected from the group consisting of Fe, Ni, Co, Mn and mixtures thereof and an alloying metal S comprising Cr, and X wherein X is at least one member selected from the group consisting of an oxide dispersoid E, an intermetallic compound F and a derivative compound G wherein said ceramic phase (PQ) is dispersed in the binder phase (RS) as particles of diameter in the range of about 0.5 to 3000 microns, and said X is dispersed in the binder phase (RS) as particles in the size range of about 1 nm to 400 nm, and wherein the ceramic phase (PQ) ranges from about 55 to 95 vol % based on the volume of the cermet.
