“…The five phases of materials used to make the quintuplex composite having a composition of 20 vol% Al 2 O 3 –20 vol% TiB 2 –20 vol% TiC–20 vol% ZrB 2 –20 vol%“ZrO 2 ,” were Al 2 O 3 , TiB 2 , TiC, ZrB 2 , and “ZrO 2 .” All the possible two‐phase solid solutions or composites of Al 2 O 3 –TiC, 17,18 Al 2 O 3 –TiB 2 , 19,20 Al 2 O 3 –ZrB 2 , 21,22 Al 2 O 3 –ZrO 2 , 23 TiC–TiB 2 , 24,25 TiC–ZrB 2 , 26 TiC–ZrO 2 , 27 TiB 2 –ZrB 2 , 28 TiB 2 –ZrO 2 , 29 and ZrB 2 –ZrO 2 30,31 have been reported in the literature. Depending on the processing conditions, this information from the literature indicates that Al 2 O 3 , TiB 2 , TiC, ZrB 2 , and ZrO 2 are compatible with one another and can be fabricated as multi‐phase composites in combination with any of these materials.…”

Multiphase ceramic composites with improved mechanical properties and high‐temperature stabilities resulting from minimized grain sizes due to extended diffusion distances are introduced. Four‐phase (quadruplex) composites of 25 vol% Al2O3–25 vol% NiAl2O4–25 vol% TiC–25 vol%“ZrO2”; 30 vol% Al2O3–30 vol% NiAl2O4–10 vol% TiC–30 vol%“ZrO2”; and 50 vol% Al2O3–20 vol% NiAl2O4–10 vol% TiC–20 vol%“ZrO2” as well as a five‐phase (quintuplex) composite of 20 vol% Al2O3–20 vol% TiB2–20 vol% TiC–20 vol% ZrB2–20 vol%“ZrO2” were fabricated using hot‐pressing procedures. The 25 vol% Al2O3–25 vol% NiAl2O4–25 vol% TiC–25 vol%“ZrO2”‡ composite, hot pressed at 1600°C for 1 h in an Ar atmosphere, had three‐point bend strength, hardness, and toughness values of 984 MPa, 1251 kg/mm2, and 4.74 MPa·m1/2, respectively. The chemically compatible, quintuplex composite consisting of 20 vol% Al2O3–20 vol% TiB2–20 vol% TiC–20 vol% ZrB2–20 vol%“ZrO2” was hot pressed at 1800°C in an Ar atmosphere for 5 h and it had hardness, bend strength, and toughness values of 1707 kg/mm2, 714 MPa, and 5.12 MPa·m1/2, respectively. The four‐ and five‐phase composites, heat‐treated under an Ar atmosphere at 1600°C for 100 h, each showed high‐temperature stabilities without any severe changes in the microstructural and mechanical properties.

“…But, self-mated metal pairs usually represented the severe adhesive wear, and the metal materials beared the electrochemical corrosion just because of their intrinsic (Wu et al, 2016;Ye et al, 2017). Compared with metals, the ceramic materials represented high hardness, high strength, and excellent corrosion resistance and outstanding tribological performance (Jianxin et al, 2006). So, more scientists focused on studying the tribocorrosion behavior of metals sliding against ceramics, which was considered to act as an inert antagonist in the tribocorrosion systems (Chen and Yan, 2012).…”

Wear in Silicon Nitride Sliding Against Titanium Alloy Pairs at Different Loads Under Artificial Seawater Lubrication

et al. 2019

Tribological behaviors of Si 3 N 4 ceramic sliding against titanium alloy at different normal loads under seawater lubricated conditions are investigated on a pin-on-disc tester. Generally, for Si 3 N 4 /titanium alloy pair, the friction coefficient increases from 0.43 to 0.67 with load increasing (from 10 to 30 N). Correspondingly, the wear rate is in the consistent case. When Si 3 N 4 slides against titanium alloy, the wear mechanism is dominated by mechanical wear even though under seawater lubrication. With load increasing, the shear force of solid shear (τ s × A r) and furrow drag S × P e S × P e aggravated, which should be responsible for the rising trend of friction coefficient and wear rate.

“…Then CaF 2 solid lubricant can be used as an addition in the fabrication of ceramic material to improve the friction characteristics. For example, the Al 2 O 3 /TiC based ceramic tool material with the combinations of CaF 2 powder possessed excellent lubricating performance especially in high-speed turning, owing to elevated temperature [35,36]. Therefore, CaF 2 was an effective and economical solid lubricant to improve the tribological properties in cutting tools.…”

To enhance the friction and wear performance of cemented carbide, textured microholes were machined on micro Electron Discharge Machining (EDM) on the tool rake face, and Calcium Fluoride (CaF2) powders were burnished into the microholes. The friction and wear characteristics of the microhole-textured tool filled with CaF2 were investigated using sliding friction tests and dry cutting tests. Results exhibited that the working temperature could affect the tribological performance of the microhole-textured tool filled with CaF2 due to the temperature-sensitive nature of CaF2. There is no obvious lubrication effect for the textured tool filled with CaF2 at room temperature, while it was shown to be more effective in improving tribological property at a cutting speed of higher than 100 m/min with a corresponding to cutting temperature of 450 °C. The possible mechanisms for the microhole-textured tool filled with CaF2 were discussed and established.
