| Abstract |
TiN-indium composite films were deposited by simultaneous sputtering of titanium and indium in a mixed Argon/Nitrogen atmosphere and characterized for tribological applications. Film compositions showed a nonlinear behavior as a function of sputter gun power. For films deposited at -50 V bias, and containing less than 29 relative percent indium, the films had a face centered cubic structure, but at higher indium contents (63-82%) the structure was not consistent with either TiN or indium. At -150 V bias, the films had either the TiN structure, In-type structure, or a mixture of the two. Atomic force microscopy images showed the formation of semispherical drops on the surface of the samples deposited at -50 V bias voltage, whereas at -150 V bias voltage the samples exhibited a smooth coating surface with occasional ellipsoidal blisters. Nanoindentation test of the films shows low hardness (5-12 GPa), but tribological testing showed that frictional behavior can be improved by moderate heating before testing, suggesting indium segregation to the surface.
