| Abstract Scope |
This study focuses on the tribological behaviors of polymer-derived SiOC bulk ceramics synthesized from 1400°C to 1500°C under a controlled argon atmosphere. Phase compositions and microstructures are analyzed via X-ray diffraction Rietveld refinement and scanning electron microscopy. Material properties including bulk density, hardness, and Young's modulus are evaluated. Friction and wear studies, conducted under loads of 5-30N and various dwell times (0-4 hours), employ a linear reciprocating wear testing approach with spherical stainless steel indenters in a ball-on-plate setup. Furthermore, a comparative analysis investigates the influence of pyrolysis temperature and phase evolution on friction and wear resistance, providing insights to optimize SiOC ceramics and enhance their tribological properties and durability. |
