Friction and wear of ceramics. Section iii case study. The friction and wear of ceramic ceramic and ceramic metal combinations in sliding contact the tribological characteristics of ceramics sliding on ceramics are compared to those of ceramics sliding on a nickel based turbine alloy. Principles and case studies.

The text is a guide to altering the microstructure of ceramics to create optimum performance in sliding and rolling contact applications. This book helps students and practicing scientists alike understand that a comprehensive knowledge about the friction and wear properties of advanced materials is essential to further design and development of new materials. Friction and wear of ceramics. Pressureless sintered b 4 c sic composite ceramics were subjected to dry sliding friction and wear against al 2 o 3 si 3 n 4 and suj2 bearing steel counterbodies at 5 n 10 n and 20 n.

The friction and wear of oxide ceramics and silicon based ceramics in air at temperatures from room ambient to 900 c in a few cases to 1200 c were measured for a. Grit size effects in two and three body abrasive wear are observed for ceramics. Friction coefficient and specific wear rate were measured and wear mechanisms were studied. Both free energy of oxide formation and the d valence bond character of metals are related to the friction and wear characteristics for metals in contact with ceramics.
