Abstract:
1. A mechanical device comprising: (a) a metal workpiece including a working surface for contacting a liquid, said working surface including a nanometric, adhesive, solid film containing carbon atoms, said film being intimately bonded to said workpiece, wherein said film is intimately bonded to said workpiece on one face of said film, and wherein an opposing face of said film is exposed, for said contacting with said liquid, and wherein said metal workpiece contains metal atoms of at least one metallic element, and wherein, in a plurality of nanometric monolayers of said working surface, said monolayers include both said carbon atoms and said metal atoms, wherein, for any particular monolayer of said monolayers, R.sub.i is an atomic ratio defined by: R.sub.i=N.sub.C/(N.sub.C+N.sub.M) wherein: N.sub.C is a number of said carbon atoms in said particular monolayer; N.sub.M is a number of said metal atoms in said particular monolayer, and i is a monolayer number of said particular monolayer, and wherein, in a first, outer monolayer of said monolayers, i equals 1, and R.sub.i is equal to at least 0.8.
