    摘要： 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 K1C fracture toughness of at least 7.0 MPa-m1/2. 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. Advantages provided by the method include, inter alia, outstanding high temperature erosion and corrosion resistance in combination with outstanding fracture toughness, as well as outstanding thermal expansion compatibility to the base metal of process units. The method finds particular application for protecting process vessels, transfer lines and process piping, heat exchangers, cyclones, slide valve gates and guides, feed nozzles, aeration nozzles, thermo wells, valve bodies, internal risers, deflection shields, sand screen, and oil sand mining equipment.
