Abstract
Abstract A high particulate energy level deposited composite film build up is presented with a layer atomically bonded to the substrate carrier material and graduated hardness material film layers including refractory material. The substrate carrier material has a relatively high thermal conductivity factor relative to refractory material used in a film layer. A dry lube reaction overcoating film or one of other dry lube films are also deposited over hard dense film surfaces for lubricity between moving parts in a heated environment.
