Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to the Special Issue of Lubricants entitled “Tribology and Tribochemistry of Ceramics”. With the development of society, energy-saving and emission-reduction have become an important trend in machine design. The demand to replace metal tribological components with more wear-resistant ceramic materials is increasing. Accordingly, the tribological properties of ceramics have received considerable scientific attention. The tribological properties of ceramics are affected by various factors, such as microstructures, mechanical properties, surface characteristics, and external factors. For ceramic materials, especially non-oxide ceramics, tribochemical reactions often occur during the sliding. Ceramic materials, such as SiC, Si3N4, Al2O3, ZrO2, and B4C, because of their superior chemical and mechanical performance, are increasingly applied in tribological components. Therefore, to meet the harsh conditions of modern machines, the current industrial trend is focusing on the increased use of advanced ceramics to more effectively reduce friction and wear in moving mechanical systems.

In this Special Issue, we would like to include a collection of research and review papers concerning the tribology and tribochemistry of ceramic materials. This Special Issue aims to provide useful support to engineers responsible for developing low-friction and low-wear ceramics in the future.

We appreciate your consideration and sincerely hope that you will accept our invitation to present your novel work to this Special Issue.

We look forward to hearing from you soon.

Computer modeling of rubbing between two surfaces with microasperities capable of expanding or contracting under conditions of frictional heating (i.e., possessing either positive and negative coefficient of thermal expansion (CTE)) allowed for the identification of wear-and-friction regimes on model ceramic materials. Assuming that no adhesion was involved in the interaction between asperities, two wear regimes—i.e., wear-free and continuous wear—have been revealed in both materials as dependent on the applied normal stress level and sliding velocity. The effect of the normal load on wear rate was similar for both positive and negative thermal expansion ceramics. Sliding velocity has a qualitatively different effect on the wear of materials with either positive or negative thermal expansion. The results indicated that the feasibility of reconstructing wear maps was common for both positive and negative CTE ceramics in terms of dimensionless mechanical and thermophysical characteristics.

We study the mechanism of formation of the multilayer structure of the subsurface regions of WC/Mn13 steel cermets after sliding on a steel disk at speeds from 10 to 37 m/s and contact pressure of 5 MPa in order to elucidate the fundamental role of the processes of tribooxidation on a worn surface in the formation of the tribomechanical properties of a large family of similar W/Fe-containing materials. It was shown that the maximum antifriction effect of WC/Mn13 steel cermets under conditions of high-speed sliding was due to in-situ generated FeWO4 that provided friction coefficient drop from ~0.17 to ~0.07 when sliding at 10 and 37 m/s, respectively. The sliding speed had its effect on the subsurface structure and tribolayer thickness, so micron-sized, mechanically mixed 3–4 μm-thick layers (MML) were generated in sliding at 10 and 20 m/s, whose wear occurred mainly by subsurface fracture and delamination of tile-shaped wear particles. Continuous tribolayers with 10–15 μm thickness were generated at 30–37 m/s with underlying zones containing fragmented and deformed WC grains. Such a structure provided plasticizing effect during sliding so that wear was mainly by flow of so plasticized subsurface layers. Full article

Lubricant additive plays an important role in reducing the friction and wear for base oil. MAX phase ceramics may have superior advantages for additive application due to their unique nanolayered structure. In this paper, Ti2SnC ceramic is prepared by sintering the elemental mixtures at 1250 °C. In addition, Cu-coated Ti2SnC ceramic is successfully prepared using a chemical plating method for the first time. It is confirmed that the Ti2SnC ceramic has good self-catalytic activity, and a layer of stacking Cu nano-particles can be deposited on the Ti2SnC surface without pretreatment. When the Cu-coated Ti2SnC ceramic powder is doped into PAO10 base oil, the oil can exhibit excellent lubrication properties, where the friction coefficient is as low as 0.095. A layer of tribo-film can be formed during the sliding process when the Cu-coated Ti2SnC ceramic is incorporated into PAO10 base oil, which can reduce the friction coefficient. The superior lubrication properties can be attributed to the synergistic lubrication effect of Ti2SnC ceramic and Cu nano-particles. Full article
