✦ Synopsis

Nanocrystalline nickel (8-28 nm) deposits were produced by direct and pulse current electrodeposition. The microhardness and microstrains in the deposits were estimated. Tribological testing indicated that the coefficient of friction (COF) for nanocrystalline nickel was almost half that of polycrystalline nickel. An important and interesting result is that extremely low COF of 0.16 can be obtained with nanocrystalline Ni coatings.

The compressive plastic strength of nanometer-scale single-crystal metallic pillars is larger than that found in conventionally sized samples. This behavior is generally associated with a change in the length scale that determines plastic behavior and the consequent inability of nanoscale samples to

Examination of pure nickel with grain sizes irom 0.12 to 130 jun showed that ant:; rhe large grain sizes exhibited stress-strain curves which agreed with a Taylor-corrected [I 1 i] single LTstal curve. Work hardening was found nearly independent of grain size for sizes below I pm. These data were fi
