Abstract:
The invention is related to a method for protecting a metal surface subject to erosion temperatures up to 850° C. The method comprises providing the metal surface with a cermet composition represented by the formula (PQ)(RS) comprising: a ceramic phase (PQ) and binder phase (RS) wherein, P is at least one metal selected from the group consisting of Group IV, Group V, and Group VI elements, Q is boride, R is selected from the group consisting of Fe, Ni, Co, Mn and mixtures thereof, S comprises Ti and at least one element selected from the group consisting of Cr, Al, Si and Y.
