“…Under high speed dry sliding conditions, localized thermal heating can be substantial. Thermal shock accelerated wear was observed and modeled by Sibley and Allen [6] in 1962. Ting and Winer proposed a thermomechanical model to include the friction induced thermal stresses in the calculations of total stress [9].…”

“…The purpose of this paper is not to provide a comprehensive list of studies but rather suggest a particular line of attack to describe ceramic wear so only selected papers are cited. Most proposed wear models are based on a specific materials pair under rather narrow operating conditions [1][2][3][4][5][6][7][8][9][10]. These models are useful in elucidating the operating wear mechanism occurred under the experimental conditions.…”

“…The first researchers in this area were A. P. Semenov, M. Peterson, C. A. Brookes, B. L. Mordike, and I. B. Sibley [2][3][4][5][6][7]. These efforts showed that, along with the dependence of tribotechnical properties on temperature and environment, it was needed to examine how the composition (stoichiometry), crystal structure, microstructure (grain size and porosity), and fine structure of sintered materials influenced the properties in question.…”

The paper overviews long-term studies into the behavior of metallic (carbides, borides, and nitrides of transition metals), and nonmetallic (boron and silicon carbides, aluminum nitride) refractory compounds as well as composite materials based on them in high-temperature friction in vacuum and air. The friction characteristics (wear rate and friction coefficient) are indicated as a function of temperature in the range from room temperature up to 1000-1400°C. Data of x-ray examination and electron microscopy of friction surfaces are cited. The fracture mechanism for contacting surfaces of materials in friction is considered.

encouraged and sponsored graduate cooperative programs in which promising young scientists (some of them NBS staff members) come to NBS to conduct research, part of which often becomes the graduate's thesis.While it is not the objective of NBS to teach and train graduate students , such a program often furthers NBS programmatic goals by attracting high caliber scientists working on areas where NBS mission lies. Many excellent research papers have results and many students, upon graduation, have chosen to stay at NBS to continue their research careers.Such programs also draw many first rate university professors to NBS through the participation of these students in NBS research programs and projects, thus fostering NBSuniversity interactions and enhancing the scientific caliber of the work and reputation at NBS and the participating university. At the same time, through the frequent contacts that NBS has with industries, a natural university/government lab/industry relationship evolves, bringing a team focus on many research projects of significant economic and/technological impacts. When appropriate, the students were supported by ECUT for some time.To this, we gratefully acknowledge the generous support of DOE ECUT, without whose support many ideas would not be explored.Stephen M. Hsu Chief, Ceramics Division ABSTRACT High temperature ceramic tribology is one of the fastest growing and least understood areas in tribology. The need to understand the mechanisms of friction and wear for ceramic materials is critical.Ceramic materials are being utilized in tool development, bearing design, materials development for low-heat-rejection diesels, automotive gas turbines, Stirling engines, and aerospace applications. Recommendations for future work on high temperature wear mechanisms of ceramic materials and the tribological testing of such materials are presented at the conclusion of this work.
