Method for preparing ammonium thiomolybdate-porous amorphous carbon composite superlubricity film

A method for preparing an ammonium thiomolybdate-porous amorphous carbon composite superlubricity film is disclosed. First, a porous amorphous carbon film is prepared by an anode layer ion source assisted plasma chemical vapor deposition method and a reactive magnetron sputtering method on a substrate. The porous amorphous carbon film is then impregnated in an ammonium thiomolybdate solution, so that the ammonium thiomolybdate is adsorbed on the porous amorphous carbon film, and the impregnated porous amorphous carbon film is air dried. During the friction process, the composited porous amorphous carbon superlubricity film prepared in the present disclosure promotes the in-situ decomposition of ammonium thiomolybdate to generate molybdenum disulfide by utilizing the friction heat at the initial stage of running-in, further to generate a graphene-like structure under the function of a catalyst, thus realizing a macroscopic super lubricity through a heterogeneous incommensurate contact between graphene and molybdenum disulfide.

FILM STACK COMPOSITION, RELATED METHOD, AND APPLICATIONS

A multi-layer PVD film stack contains high index of refraction base material(s), followed by a semi-transparent low index of refraction cap layer. The base layer(s) provide the color range of the film. The thickness of the cap layer dictates the degree to which the film retains the color properties of the base material and the reflectivity of the cap material. The cap layer not only increases the reflectivity of the base material, but it also decreases the reflectivity lost when the PVD film is topcoat lacquered. The lacquering is advantageous in protecting the PVD film but it decreases the reflectivity of the high index of refraction materials (generally n value>1.9 at 632 nm). These materials are desirable due to their color properties but are too dark after lacquering for many commercial applications. We address this problem by utilizing a high refractive index metal, or metals, as an opaque first layer followed by a thin semi-transparent second layer of a low refractive index metal. Upon topcoat lacquering, the resulting coating retains most of the aesthetically pleasing properties of the base metal(s) but minimizes the darkening of the metal(s) after topcoat due to the low refractive index of the second layer, which is in contact with the lacquer.
