  • Functionally graded carbides
    Patent number: 10501376
    Abstract: A functionally graded carbide body (400) can include a group 5 metal carbide substrate having a bulk composition region (410) that contains at least 70 wt % of a rhombohedral ?-phase carbide. A ?-phase-rich region (420) having a ?-phase-rich composition can be at a surface (430) of the substrate, and a phase composition gradient region (440) can transition from the ?-phase-rich composition region at the surface to the bulk composition region at a gradient depth (450) below the surface.
    Type: Grant
