“…The solid lubricants, like metal oxides with Magnéli phase [13][14][15] (like Ti 2 O 3 ), metal oxides with low shear strength (like WO 3 ) [16,17], and the good lubricant WS x , could reduce the friction and wear by separating the frictional surfaces of two friction mates. Owing to the low shear strength, the solid lubricants could change the friction and wear of the two friction mates into the inner friction and wear of themselves.…”

“…The lubricating mechanism under dry sliding mainly includes three parts: lubrication of Ti oxides, lubrication of W oxides, and interaction effects between Ti oxides and W oxides. The first part, lubrication of Ti oxides, is considered as the self-lubricating mechanism of Ti nitrides [13,14]. Ti 2 O 3 could be formed on the coating surfaces by oxidation reactions [6], or produced as tribofilms on the frictional surfaces during the friction and wear process.…”

“…and their alloys and several carbides and nitrides such as TiC, TiN, TiCN exhibit good tribological properties at elevated temperatures owing to the formation of lubricious oxides by tribooxidation. [67][68][69] For tribological materials, both the excellent tribological properties and good mechanical properties are necessary. Cai et al [70,71] introduced SiC and B 4 C into C/C composites as the secondary matrix phase, simultaneously improving the mechanical and tribological properties.…”

Carbon fiber reinforced ceramic matrix composites (CFCCs) are promising materials for hightemperature applications. Due to the unique nanolaminated structure and special properties, the MAX phases are promising reinforcements for CFCCs. As one representative member of the MAX phases, Ti 3 SiC 2 has been in situ formed in C/C-SiC and C/SiC composites by a joint process of slurry infiltration and liquid silicon infiltration in recent years. The composites containing Ti 3 SiC 2 exhibited improved mechanical properties, tribological performance, and ablation behavior compared with those of unmodified composites. The introduction of MAX phases in CFCCs could extend their application fields effectively, and it is expected to bring more benefits to CFCCs by introducing the MAX phases in the future.

“…This will result in increasing tool wear and hence reduction in tool life [2]. It was thought that it was promising to develop self-lubricated tools by forming an in tribological film with low friction between the work material and tool during the machining process [2][3][4][5][6][7][8][9].…”

Abstract. Micro-holes were fabricated using micro-EDM on the surface of WC/TiC/Co carbide, CaF2 solid lubricants were filled into these micro-holes to form self-lubricating tool (MST). Dry cutting tests on AISI 1045 hardened steel were carried out with the MST tools and conventional tools (CT). The cutting temperature were measured and compared. The results indicated that the cutting temperatures with the MST cutting tools were reduced compared with the CT tools, and the cutting speeds were found to have a profound effect on the cutting temperatures variations of the MST tool. Two mechanisms of cutting temperature decrease are found, the first one is due to the formation of a discontinuous CaF2 lubricating film on the tool rake interface, which may decrease the average shear stress; the other one can be inferred from the microholes on the rake face, which contribute to the reduction of contact length at the tool-chip interface
