In the present paper, the influence of self-mated friction materials on the tribological properties of hydrogenated amorphous silicon films (a-Si:H films) is studied systemically at high temperature. The results are obtained by comparing the tribological properties of a-Si:H films under different friction pair materials and temperatures. The a-Si:H films exhibit super-low friction of 0.07 at a temperature of 600 °C, and ceramic materials are appropriate for anti-friction behaviors of a-Si:H films at high temperature. The results of tribotests and observations of the fundamental friction mechanism show that super-low friction of a-Si:H films and ceramic materials of the friction system are involved in high temperature oxidation; this also applies to the tribochemical reactions of a-Si:H films, steel and iron silicate in open air at elevated temperature in the friction process.

Nowadays, new materials with enhanced tribological properties are required to fulfil the new demanding working conditions of more efficient and eco-friendly industrial processes. To achieve this goal, we propose the addition of graphene nanofillers, a very attractive self-lubricating solid, to ceramic materials for improving their tribological responses. As proof of concept, here we present the role of the graphene nanoplatelets (GNPs) on the friction and wear resistance of two different graphene/ceramic nanocomposites, in particular, GNPs/silicon nitride and GNPs/silicon carbide materials. The tribological tests evidence that GNPs are ideal nanofillers to increase the wear resistance, especially under high contact pressures, because the nanoplatelets are exfoliated during the sliding motion and lead to the formation of a carbon-based protecting film; whereas the benefits on the friction depend on the tribo-testing conditions.

It is well known that experimentally-determined values of wear resistance are not materials’ constants, but rather measured responses to a particular set of conditions imposed by a specific wear environment. Nonetheless, a material’s tribological performance is often estimated based on its bulk material properties. For applications requiring abrasive wear resistance, for example, ceramic materials are traditionally selected based on their hardness and fracture toughness, which are assumed to be proportional to the wear resistance. However, recent studies have indicated that for many commercially-important ceramic materials, subtle differences in the microstructure (not always reflected in measured values of bulk hardness and fracture toughness), can lead to large variations in the abrasive wear resistance.A number of microstructural variables can influence the tribological properties of a ceramic material: matrix grain size, matrix grain shape, the presence of intra-and inter-granular second phases, and the presence of transforming second phases (in zirconias and zirconia-toughened ceramics, for example).

Ceramic materials are widely used in various industrial applications on components exposed to high temperature, wear, and corrosive conditions. Nowadays, nanostructured materials are of particular scientific interest because of their physical and mechanical properties, which are superior to those of conventional materials. Plasma spraying is one of the surface engineering techniques for depositing of the coatings with wide variety of properties necessary for industrial use. The work is concerned with a study of the microstructure and tribological properties of plasma sprayed coatings with nanostructured and conventional Al2O3-13TiO2 powders. The coatings were sprayed by means of a Plancer PN-120 plasma system. A T-01 ball on disc tribological tester was used to study their coefficient of friction on the basis of the friction force obtained in the course of continuous measurement at a set load. Results of investigations were compared with properties of the coatings sprayed with standard Al2O3-13TiO2. The nanostructured Al2O3-13TiO2 coating showed the lower coefficient of friction in comparison to the coatings sprayed from the conventional powder.
