Dr. K. Cherian provides a summary of his work researching atmospheric pressure microwave plasma processing technologies. This includes using microwave plasma to carry out processes like sintering, carburizing, nitriding, and brazing of technical ceramics and metals. Some key advantages identified are lower processing temperatures, shorter cycle times, and improved or comparable material properties compared to conventional methods. Specific examples discussed include carburizing gears to greater depths in less time and sintering ceramic cam lobes with better hardness.
