“…The dependence of the friction coefficient and wear for metallic compounds, such as transition metal diborides, on the testing temperature in open air is determined by the oxidation susceptibility of materials and the nature of oxide films formed on friction surfaces [23]. Metallography and microhardness test [23] showed how oxide films formed and evolved on the rubbing surfaces of borides.…”

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.

“…Metallography and microhardness test [23] showed how oxide films formed and evolved on the rubbing surfaces of borides. Considering these results and x-ray phase analysis, the entire temperature range for the friction and wear of transition metal borides in open air may be divided into three areas.…”

The nonlubricated sliding wear of SiC–B4C–Si cermets against a diamond indenter was studied. The cermets containing 2, 5, 10, and 20 wt.% of Si were fabricated by both conventional sintering and spark plasma sintering (SPS) techniques. It has been observed that wear depth, volume of the wear debris, and wear rate increases with increasing applied load for both cases. Minimum wear depth and lowest wear rate was obtained for the cermet containing 10 wt.% Si. Three-body abrasion is the main wear mechanism which results in surface delamination, and formation of grooves and cavities on the damaged surface.
