“…Above 800°C, return and recrystallization are observed. They are accompanied by the growth of mosaic blocks and decrease in lattice distortion, thus leading to a decrease in hardening, which is complete for TiC and partial for NbC, as confirmed by microhardness measurements [16]. Electron microscopy of the TiC contact area shows that the brittle fracture of surface layers prevails between 20 and 400°C [19].…”

The paper overviews long-term studies into the behavior of metallic (carbides, borides, and nitrides of transition metals), and nonmetallic (boron and silicon carbides, aluminum nitride) refractory compounds as well as composite materials based on them in high-temperature friction in vacuum and air. The friction characteristics (wear rate and friction coefficient) are indicated as a function of temperature in the range from room temperature up to 1000-1400°C. Data of x-ray examination and electron microscopy of friction surfaces are cited. The fracture mechanism for contacting surfaces of materials in friction is considered.

“…Examining the high-temperature friction and wear of metallic refractory compounds, such as transition metal carbides, borides, and nitrides [13][14][15][16][17][18][19][20], in vacuum shows that their friction coefficient and wear behave similarly over a wide temperature range (Figs. 1-3).…”
