“…The reactions between B 4 C and Ti are widely reported in the literature − and known to be highly exothermic. The nature of this reaction between titanium metal and boron carbide powders can be classified as a SHS, given that it has an adiabatic temperature of more than 2200 °C .…”

Square-shaped boron carbide ceramic composites have been produced by spark plasma sintering with the addition of 5 to 20 vol % titanium metal powder in the B 4 C matrix in order to initiate an in situ self-propagating high-temperature synthesis (SHS) of TiB 2 . The SHS reaction not only enhances many of the physical and mechanical properties of B 4 C, but also reduces the required sintering temperature and pressure because of the enthalpy of reaction between metallic Ti and B 4 C. Sintering has been carried out in the SPS-temperature range of 1450 to 1550 °C with a uniaxial pressure of 40 MPa and a dwell time of 4 min under a 1 atm argon atmosphere. The effects of various amounts of Ti additions and sintering temperature on the phase composition, density, hardness, fracture toughness, and microstructure are examined. X-ray diffraction and transmission electron microscopy evaluations have shown that added Ti completely transforms into TiB 2 , resulting in a core−shell microstructure with a carbon core, surrounded by a TiB 2 shell in the B 4 C matrix. Moreover, by carrying out a control experiment where TiB 2 was added instead of Ti, and performing a molecular dynamics simulation of the B 4 C-Ti interface, the significance of the in situ SHS process has been validated.

“…One of the most frequently used nickel-based ceramics composites are Ni-Cr composite materials with varying additions of chromium or its compounds [ 9 , 10 , 11 , 12 ]. Additionally, because of their good properties, the Ni-Cr composites have been widely used as a coating material, to modify other materials, for example, stainless steel [ 13 , 14 , 15 , 16 ]. As Ni-Cr ceramic composites are so widely used, it is important to improve their wear properties, especially at high temperature.…”

Nickel composites doped by chromium and calcium fluoride were produced by powder metallurgy. The friction coefficient of the samples containing 20% of the CaF2 was lower at elevated temperatures (600 °C) than the friction coefficient for the Ni-50%NiCr(80/20) composite (0.14 vs. 0.20). Sample surfaces were analyzed by the scanning electron microscope (SEM). EDS analysis proved tribofilm formation on the surface of the sample with CaF2 addition. A laser confocal microscope (LCM) was used to investigate the surface condition of the counter-sample after wear tests. The presence of the tribofilm reduced the wear of the frictional pair, and because of that the wear tracks were smooth. Tribofilm limited the abrasive wear and ploughing. Therefore, the tribofilm protected the sample and counter-sample from wear.

“…Carbide ceramics have many outstanding characteristics like excellent wear resistance, − high hardness, − and low density . Accordingly, the tribological properties of many carbide ceramics, such as SiC, B 4 C, WC, NbC, TaC, TiC, and nano MXenes Ti 3 C 2 , have drawn considerable attention in basic and applied research.…”

The tribological properties of carbide ceramics (SiC, B 4 C−SiC, and B 4 C) sliding against SiC balls in water at a normal load of 20 N in ambient conditions were investigated. Compared with traditional SiC ceramics used as mechanical seal materials, B 4 C−SiC ceramics exhibit lower friction and wear under water lubrication. The lower coefficient of friction of B 4 C−SiC ceramics is caused by the nanorelief with a depth of 12 nm formed on their friction surfaces. The water stored in the valleys of nanorelief can provide continuous lubrication to the B 4 C−SiC ceramic friction surfaces, and the good load carrying capacity makes B 4 C−SiC ceramics exhibit lower COF under higher load (20 N). In situ formed nanorelief can show beneficial influence on the frictional property of materials under water lubrication. The formation of nanorelief on B 4 C−SiC ceramics is the result of competition between mechanical wear and tribochemical wear under water lubrication. B 4 C−SiC ceramics with better tribological properties are expected to replace traditional SiC ceramics as mechanical seal materials under water lubrication. A design idea that using the microhardness difference between the two phases of composite ceramics to in situ prepare relief on the composite ceramic surface to improve the frictional property under water lubrication has been proposed in this study.
