“…After adding CeO 2 , the oxide of cerium and the oxide of silver react with each other during friction at high temperature and formed compound oxide Ag 2 CeO 4 , which relieves the adhesive tendency. Furthermore, with the increase of temperature on the friction surface, the low-melting-point sulfides (Cr x S y ) are partly melted and flow easily, smeared on the friction surface and formed a lubricating film, which are responsible for the low friction at 600 • C [19]. For the composite with silver and CeO 2 , the friction coefficients drop to below 0.16.…”

“…Unlike traditional solid lubricants with 2D structure, these materials have stronger intralayer and interlayer covalent bonds. The intralayer covalent bonds is responsible for the brittleness and hardness of the ceramics, and as a result of their brittle nature, the lubricating property of ceramic materials is known to depend heavily on their microstructure under varying temperatures [ 172 , 173 , 174 , 175 ]. In the case of ceramic materials, the wear and failure happen due to crack initiation and propagation.…”

This paper aims to provide a theoretical and experimental understanding of the importance of novel 2D materials in solid-film lubrication, along with modulating strategies adopted so far to improve their performance for spacecraft and industrial applications. The mechanisms and the underlying physics of 2D materials are reviewed with experimental results. This paper covers some of the widely investigated solid lubricants such as MoS2, graphene, and boron compounds, namely h-BN and boric acid. Solid lubricants such as black phosphorus that have gained research prominence are also discussed regarding their application as additives in polymeric materials. The effects of process conditions, film deposition parameters, and dopants concentration on friction and wear rate are discussed with a qualitative and quantitative emphasis that are supported with adequate examples and application areas and summarized in the form of graphs and tables for easy readability. The use of advanced manufacturing methods such as powder metallurgy and sintering to produce solid lubricants of superior tribological performance and the subsequent economic gain from their development as a substitute for liquid lubricant are also evaluated.

“…To fabricate the metal ceramic matrix with orderly micropores structure, a mixture of 74.1 vol.% Fe-Cr-W-Mo-V metal alloy powder and 18.5 vol.% TiC powder together with 7.4 vol.% complex poreforming agent was milled for 2 h and then was coldcompressed into a mold at 600 MPa and was sintered at about 1230 ∘ C in a vacuum furnace [8]. The specimen of the porous matrix and its microstructure are shown in Figure 1.…”

A novel ceramic composite inward gradient distribution layer has been developed. The layer is a lubricating layer in which soft-metal lubricants are compounded into the ceramic matrix by high frequency induction infiltrating method. The design of the layer and its lubricating mechanism are investigated in the paper. The results show that the property of the layer greatly depends on the wetting angle of the soft-metal lubricants on the matrix and the proportion of Ag, Cu, Sn, and Pb as well as the infiltrating parameters. Based on a lot of experiments, a novel inward gradient layer with Pb28Sn19Ag6Cu has been developed. The layer has an excellent lubricating property (friction coefficient about 0.2~0.3 at 600°C). The research reveals the lubricating mechanism, observing the phenomenon that the soft-metal in the matrix diffuses out of the frictional surface, and measures the lubricating film thickness as about 20 μm on the worn surface.
