MAX phase containing Ti-Al-(C, N) composite coatings is promising in marine engineering due to the improved tribocorrosion performance of titanium alloys. Therefore, novel Ti-Al-(C, N) composite coatings were prepared in this study using laser cladding on TC4 substrate. Electrochemical performances of as-obtained composite coatings were then analyzed under static and dynamic conditions in an artificial seawater environment, and their tribocorrosion behaviors and corrosion–wear synergism mechanism were examined by a tribocorrosion test system. The results showed that the existence of self-lubricating phases Ti2AlC and Ti2AlN in composite coatings and the corrosion products with a certain lubrication effect generated during the friction process kept the average friction coefficient at a low level. With the increase of load, the mechanical failure of the passive film in the friction process was enhanced, the adsorption of corrosive medium on the surface of the passive film led to its active dissolution, and the wear volume increased from 1.45 × 10−2 to 3.24 × 10−2 mm3. The corrosion of composite coatings in artificial seawater was not extensive, and volume loss caused by tribocorrosion was mainly determined by wear behavior. In sumary, the coatings exhibited good bearing capacity in the marine environment, thereby showing broad prospects for marine equipment applications.

“…The tribological behaviors of MAX phases have also attracted increasing attention due to their unique laminate structure [5,6]. It is well known that MAX phases can exhibit better lubrication properties only under several certain conditions, such as at high speeds [7,8], under a low load [9], at a micro-scale [10], against some certain counterparts [11], in a vacuum environment [12], or under a water environment [13]. Furthermore, it has been reported that MAX phases could play lubricating roles in reducing friction and wear when doped into a NiAl or TiAl matrix, due to their tribo-oxidation effect [14,15].…”

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.

“…Ceramic materials are known for their outstanding hardness, high strength, excellent chemical stability, and corrosion resistance compared with traditional metal pairs, which make them promising candidates for marine friction pairs. In this respect, more and more scholars are paying attention to the tribological performance of ceramics in marine environments [9][10][11]. In particular, silicon nitride can react with water molecules during the friction process to form silica gel, which, afterwards, transforms into a surface lubricating film on the wear surface [12][13][14][15].…”

In the present study, the friction and wear behaviors of Si3N4-hBN(Hexagonal boron nitride) ceramic composites against polyether-etherketone in artificial seawater were investigated, and the sliding speed was varied from 0.52 to 1.73 m/s to study the effect. It was found that the friction coefficients and wear rates decreased with the increase in sliding speed for Si3N4-hBN (with the hBN content ranging from 5% to 20%) against PEEK(Polyether-ether-ketone); the sliding pairs represented an upward trend as the speed increased for Si3N4-hBN (with an hBN content of 0 and 30%) against PEEK. This result was mainly attributed to complex friction resistance sources, such as mechanical meshing and the shear strength of soft tribofilm. On the other hand, both the hBN content and sliding speed had a significant effect on the tribological performance of the Si3N4-hBN/PEEK pairs. Meanwhile, the lowest friction coefficient of 0.07 and wear rates below 10−6 mm3/Nm were obtained from the Si3N4-20%hBN/PEEK pair at the speed of 1.73 m/s.
