An improved process for the creation or formation of nanocrystalline
layers on substrates' surfaces is provided. The process involves
"prescuffing" the surface of a substrate such as a metal by allowing
friction to occur on the surface by a load-bearing entity making rubbing
contact and moving along and on the substrate's surface. The
"prescuffing" action is terminated when the coefficient of friction
between the surface and the noise is rising significantly. Often, the
significant rise in the coefficient of friction is signaled by a change
in pitch of the scuffing action sound emanating from the buffeted
surface. The "prescuffing" gives rise to a harder and smoother surface
which withstands better any inadequate lubrication that may take place
when the "prescuffed" surface is contacted by other surfaces.
