1. A laser cladded bimetallic material, comprising:
(i) a high temperature alloy substrate, and (ii) a precipitated cermet composition comprising one or more metals, M, from a metal alloy binder,
wherein the high temperature alloy substrate comprises a high temperature alloy substrate selected from the group consisting of (i) Ni-based, high Cr alloys, (ii) FeNi-based alloys, (iii) FeNiCo-based alloys, (iv) NiCo-based alloys, (v) Ni-based alloys, (vi) Steam Cracker Alloys, (vii) Austenitic Stainless Steels and mixtures thereof; wherein the precipitated cermet composition comprises:
(a) at least one ceramic phase material selected from the group consisting of metal carbides (MxCy), metal nitrides (MxNy), metal borides (MxBy), metal oxides (MxOy), metal carbonitrides (MxCNy), and mixtures of thereof; wherein:
wherein the one or more metals, M, is at least one element selected from a group consisting of titanium (Ti), Zirconium (Zr), Hafnium (Hf), Vanadium (V), Niobium (Nb), Tantalum (Ta), Molybdenum (Mo), Tungsten (W), Iron (Fe), Nickel (Ni), Cobalt (Co), Chromium (Cr), Aluminium (Al), Silicon (Si), Manganese (Mn), and mixtures of thereof;
x is a whole or fractional numerical value ranging from 1 to 26; and
y is a whole or fractional numerical value ranging from 1 to 6; and
(b) at least one metal alloy binder phase corresponding to the metal alloy binder, wherein the at least one metal alloy binder phase comprising
(i) about 28.0 to about 33.0 wt. % chromium (Cr);
(ii) about 0.5 to about 2.9 wt. % carbon (C);
(iii) about 4.1 to about 30.0 wt. % of an alloying element selected from the group consisting of Iron (Fe), Cobalt (Co), Aluminum (Al), Silicon (Si), Manganese (Mn), Copper (Cu), Titanium (Ti), Zirconium (Zr), Hafnium (Hf), Vanadium (V), Niobium (Nb), Tantalum (Ta), Molybdenum (Mo), Tungsten (W), and mixtures of thereof; and
(iv) the balance being nickel (Ni),
wherein the wt. % is based on the total weight of the alloy.
