Paper I (i) On the elastic constants of thin solid lubricant films

摘要: The literature was searched to find numerical values of elastic constants for layered hexagonal lubricants (e.g., graphite, MoS 2 , NbSe GaSe and InSe) selected hardcoat underlays such as TiN TiC. data are critically reviewed accuracy usefulness a tribologist. An attempt is made correlate the electronic crystal structure solid with degree ionic-to-covalent bonding that both characterizes systems determines magnitude their constants. basic intent provide appropriate Young's modulus (E), shear (G) Poisson's ratio (u) computer diagnosticians, who need substitute realistic into iterated programs predicting actual concentrated contact stresses associated hardcoat/softcoat systems.
