Summary of Expertise: Listed with other top experts in: 
Expert has devoted most of his recent career to developing processing techniques, procedures, equipment, and control systems for preparing powders and forming/shaping components. This work has covered the full range of operation necessary for manufacturing ceramic components. He is familiar with powder synthesis (wet and dry), powder preparation (wet and dry), binders, forming/shaping (wet and dry, casting, pressing) and sintering. This experience includes both laboratory research and commercial manufacturing.

Expert has devised new processing techniques and schemes such as the semicontinuous classification of submicron size powders, and the continuous chemical synthesis of monosized ceramic powders. His work has included dispersion and slip/slurry preparation, and forming/shaping techniques. He has developed procedures for semicontinuous production of narrow size distribution powders, and application of instrumentation, sensors, and controls for liquid based processing of powders.

process design

Expert has used centrifuges to classify (separate) sub-micron particles in a semicontinuous separation system and to centrifugally cast net-shape parts from high solids content suspensions (slurries).

ceramic centrifugation

Expert is experienced with plasma spraying to prepare and apply composite materials for a variety of applications including electrical resistance heating and chemical corrosion resistance. He has used plasma spraying for the direct fabrication of a variety of components and shapes from metal, ceramic, and composite materials. He has also worked on the development of multi-layered graded and coated parts fabrication as well as single composition, pipes, crucibles, and other items. Expert was involved with preparing powders for use in plasma spray equipment and using powders for forming devices (components) as well as coatings. He has developed powders for controlled (engineered) microstructures and techniques to fabricate net-shape, controlled, macrostructure components. He has also used plasma spraying to fabricate magnetohydrodynamics (MHD) electrode modules.

plasma spraying

Expert's work in this area is mainly with ceramic materials, but also includes metals, polymers, and mixed material composites. He is familiar with metal matrix (MMC) and ceramic matrix (CMC) composites, as well as using and developing interconnected, interpenetrating phase composites. These materials were developed for various specific applications, such as electrical resistance heating, and for dental prostheses. Expert has worked with materials for electrical and mechanical (structural) applications. Forming (fabrication) techniques for these materials (metals, ceramics, cermets) include arc plasma spraying, colloid (filter) pressing, slip casting, dry pressing, and centrifugal casting. Primarily, his efforts have been directed to net shape fabrication.
