Effect of grain size on the tribological behavior of nanocrystalline nickel
Nanocrystalline nickel (8–28nm) 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.
