Abstract
The present invention is directed to a method for protecting metal surfaces in oil & gas exploration and production, refinery and petrochemical process applications subject to solid particulate erosion at temperatures of up to 1000° C. The method includes the step of providing the metal surfaces in such applications with a hot erosion resistant cermet lining or insert, wherein the cermet lining or insert includes a) about 30 to about 95 vol % of a ceramic phase, and b) a metal binder phase, wherein the cermet lining or insert has a HEAT erosion resistance index of at least 5.0 and a Kfracture toughness of at least 7.0 MPa-m. The metal surfaces may also be provided with a hot erosion resistant cermet coating having a HEAT erosion resistance index of at least 5.0.
