Microstructure of laser clad MoSi2 metal silicide composite coating
The metal siliclde MoSi2 is regarded as a promising candidate high-temperature structure material due to its outstanding balance of high melting point (2030℃ ) .lower density(6. 24g/cm3) , excellent oxidation resistance. MoSi2 metal silicide composite coating was fabricated on substrate of nickel- plate by laser cladding using Mo - Si elemental powder blends. Non -equilibrium rapid solidified microstructure was characterized by SEM.XRD and EDS. Microhardness of the composite coating was measured by MH6 semi automatic Vickers hardness tester.
