5. 8. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing

   Author : Lars Kahlman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal wear; ceramic composite; face seal; engineering ceramic; erosion; hybrid bearing; thermal spalling; lubrication; tribology; abrasive waterjet; abrasive wear;

   Abstract : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. READ MORE

6. 9. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements

   Author : Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; Materials science; Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

   Abstract : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. READ MORE

7. 10. High-entropy boron-carbide and its composites

   Author : Hanzhu Zhang; Farid Akhtar; Peizhong Feng; Yong Zhang; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

   Abstract : High-entropy alloy (HEA) is a multicomponent alloy material that contains five or more principal elements in equi- or near equi-atomic ratios. The entropy stabilisation leads to the formation of a crystalline solid solution accommodating the principal elements. READ MORE
