Hardening of nickel alloys by ion implantation of titanium and carbon
Conference

OSTI ID:459694
Dual ion implantation of Ti and C was shown to produce an amorphous surface layer in annealed bulk Ni, electroformed Ni, and electroformed Ni{sub 0.75}Fe{sub 0.25}. Diamond-tip nanoindentation coupled with finite-element modeling quantified the elastic and plastic mechanical properties of the implanted region. The amorphized matrix, with a thickness of about 100 nm, has an intrinsic hardness near 16 GPa, exceeding by an order of magnitude the value for annealed bulk Ni. Implications for the control of friction and wear in microelectromechanical systems are discussed.
