The Tribological Performances of the Boron Carbide Films ...

May 20, 2019· Abstract. In the previous literatures, the friction reduction of boron carbide (B 4 C) with the increasing relative humidity was mainly attributed to the formation of boric acid during the friction tests. In the present investigation, however, low friction coefficient was obtained under wet air (85% RH) without the formation of boric acid, suggesting that there is another low friction mechanism.

Erosion wear of boron carbide ceramic nozzles by abrasive ...

Nov 05, 2005· Although there is considerable interest in the erosion wear of ceramic materials, little work has been published on the impact erosion behaviors of boron carbide ceramic nozzles in abrasive air-jet processes. In this study, monolithic boron carbide ceramic was produced to be used as nozzle materials by hot pressing.

Boron carbide - Wikipedia

Boron carbide (chemical formula approximately B 4 C) is an extremely hard boron–carbon ceramic and covalent material used in tank armor, bulletproof vests, engine sabotage powders, as well as numerous industrial applications. With a Vickers Hardness of >30 GPa, it is one of the hardest known materials, behind cubic boron nitride and diamond.

Boron - Wikipedia

Boron carbide is a ceramic material which is obtained by decomposing B 2 O 3 with carbon in an electric furnace: 2 B 2 O 3 + 7 C → B 4 C + 6 CO. Boron carbide's structure is only approximately B 4 C, and it shows a clear depletion of carbon from this suggested stoichiometric ratio. …

Oxidation behaviour of boron carbide powder - ScienceDirect

Jan 25, 2007· Isothermal oxidation behaviour of powdered boron carbide (B 4 C) with the fine (1.52 μm), medium (22.5 μm) and coarse (59.6 μm) particle size has been studied in air ranging from 500 to 800 °C. The oxidation rate strongly depends on the particle size of boron carbide and temperature.
