Mechanical and thermal applications of low-pressure diamond

During the last decade several applications for low-pressure diamond were developed. Main products are diamond windows with their high transparency over a wide range of wavelength; heat-spreaders with very high thermal conductivity, and wear resistant tools because of diamonds superhardness. Starting with a short description of the most efficient diamond deposition methods (microwave, hot-filament, plasma-jet and are discharge) the different applications will be described. Finally problems of reproducibility, reliability and economical mass production will be discussed.
