| Popis: | The objective of the present study was to assess the tribological properties and the wear behavior of silicon carbide and boron carbide ceramics, produced by the plasma pressure compaction sintering process. Reciprocating sliding tests were executed to evaluate the tribological behavior of silicon carbide and boron carbide. Samples of each material with distinct values of surface roughness Ra were tested. Wear mass loss, coefficients of friction and wear mechanism of the boron carbide and silicon carbide were evaluated by means of microscopes and an energy-dispersive spectroscopy probe. The coefficient of friction of the evaluated boron carbide was found to be 0.8, and the surface roughness affects only the starting transient, while for silicon carbide the steady-state value ranges from 0.5 to 0.8 depending on the roughness value Ra. |
