Ceramics and its Importance

Himalayan Physics, 2013

The term "ceramic" once referred only to clay-based materials. However, new generations of ceramic materials have tremendously expanded the scope and number of possible applications. Many of these new materials have a major impact on our daily lives and on our society. Ceramics has advanced far beyond its beginnings in clay pottery. Ceramic tiles cover the space shuttle as well as our kitchen floors. Ceramic electronic devices make possible high-tech instruments for everything from medicine to entertainment. Clearly, ceramics are our window to the future.The Himalayan Physics Vol. 4, No. 4, 2013 Page: 80-82 Uploaded date: 12/23/2013

To assess the tribological issues, needs, and priorities for research on friction, wear, and lubrication of ceramic materials relevant to gas-fired prime movers. Currently, small, but well established, markets exist for gas-fired reciprocating engines. The oil, gas, and agricultural industries use such engines to provide power to drilling operations, air compression, and fluid pumping. In these applications, the availability of the fuel may be a greater factor than efficiency in determining usage. Similarly, gas-fired turbine engines are used widely in power plants. In the latter application, reliability, lifetime, and long time intervals between maintenance are more important considerations than efficiency. Further, potential new markets exist, in both the near term and the far future, that could significantly expand the utilization of natural gas prime movers. In these potential markets, however, the efficiency of the engine is a critical factor affecting the choice of the fuel source. In the near term, for example, power cogeneration could become an important market in response to the higher cost of electricity during peak demand periods. In the far future, the clean burning characteristics of natural gas may make it the most desirable fuel for advanced, high temperature, high efficiency engines. In both cases, the question of efficiency requires a clear resolution of tribological issues, with the most urgent attention being focused on the unique conditions pertaining to gasfired prime mover environments. A critical assessment of the current state-of-the-art of the tribology of ceramics is made. While there are many research issues related to the general application of ceramics in machinery, wear parts, bearings, biomaterials, and liquid-fueled heat engines, there are unique research needs specific to the gas industry. In particular, advanced heat engines designed specifically for gas burning used in energy generation and transportation offer exciting prospects as well as difficult challenges in materials selection, testing, design guidelines, and life predictions. The development of the technology for high efficiency gas-burning prime movers is deemed necessary to maintain current and projected utilization levels of natural gas. Further, problems associated with high temperature lubrication of liquid-fueled heat engines, in terms of dispersing soot particulars and the neutralization of sulfuric acidic species (derived from sulfur compounds in vii liquid fuels), may delay or prevent the commercialization of high efficiency liquid-fueled adiabatic engines,. Consequently, the clean burning characteristics of natural gas may offer a unique opportunity to capitalize on this market. Current tribology research efforts on ceramics are plagued by inconsistent methodology, lack of materials characterization, lack of environmental control, and nonuniform sample cleaning and preparation procedures. These practices yield contradictory data and make generalizations of friction and wear characteristics of materials impossible. The ever changing processing techniques for ceramic materials add further measures of confusion. Design guidelines and materials selection become crucial issues. Wear life is controlled by effective lubrication, but lubrication of ceramic materials currently is not understood. Hence, there is no effective lubricant presently available for ceramics at high temperatures. Effective lubrication is also controlled by environmental factors. The influence of gas combustion products on lubricants and ceramic surfaces, therefore, becomes a key focus for GRI. Based on this assessment, it is recommended that GRI accelerate research in: (1) ceramic materials selection guide for optimum wear life under gas-burning conditions; (2) lubrication research in defining the chemistry, materials, and additives that will function under high temperature gas-burning conditions; and (3) effects of microstructure on wear resistance, surface reactivity, and lubrication requirements under gas combustion environments. While there is a large parallel effort in developing liquid-fueled heat engines, and while many problems identical in form emerge, it is not clear that solutions that may be derived from liquid-fueled heat engine research can be utilized readily for gas-fired prime movers. The very nature of tribology is governed by systems (speed, load, geometry temperatures, pressures, and lubrication) and environments (combustion gases, contaminants, oxidation, corrosion, and competing processes). Therefore, solutions specific to GRTs needs may not be available from other sources that are not gas related. Results from projects such as materials development, however, can provide useful leads, but even these results must be tested under specific gas-fired prime mover conditions to establish their utility to the gas industry. Prompt implementation of the research in the recommended areas will not only ensure GRI's position on parallel technology development, but also may provide a unique opportunity to exploit to the fullest advanced technologies for increased utilization of natural gas.
