  • Coating for a titanium alloy substrate
    Patent number: 9308090
    Abstract: The present disclosure relates, at least in part, to a surgical implant and a method for manufacturing the surgical implant. In one embodiment, the surgical implant comprises a metallic substrate; a tantalum interlayer disposed adjacent to the metallic substrate and comprising ?-tantalum and amorphous tantalum; at least one DLC layer disposed adjacent the tantalum interlayer; wherein the amorphous tantalum has a phase gradient increasing from the metallic substrate side to the DLC side; wherein the DLC layer has a hardness value and an elastic modulus value; and wherein the hardness value has a gradient increasing away from the tantalum side; and wherein the elastic modulus value has a gradient from the tantalum side.
