dense ceramic and homogeneous carbon nanotube / silicon nitride elaboration process and its applications.

摘要

dense and homogeneous carbon nanotube / silicon nitride manufacturing process and ceramic applications.; The present invention relates to a ceramic silicon nitride compound comprising a dense matrix, nonporous silicon nitride comprising carbon nanotubes (CNTs) uniformly dispersed within said matrix and undegraded. Also, a method for manufacturing such composites is described by dispersing carbon nanotubes in the matrix of silicon nitride and subsequent sintering by electrical discharge in a vacuum atmosphere. These materials can be used for the manufacture of tools, devices, or any element that requires a good thermomechanical behavior and tribological, for example, cutting tools or wear components, for example, valves, bearings and bearing.
