Popis: Diamond deposition on carbon substrates is difficult, because atomic hydrogen needed for the diamond growth, attacks the graphitic and amorphous carbon of the substrate. To reduce the etching effect, the duration till diamond layer formation should be short.By controlling the diamond deposition conditions, boron addition and seeding with diamond prior to the deposition, the formation of diamond coatings is possible.Diamond coated carbon substrates are of high interest for electrochemical applications because they show electrical conductivity and are chemically inert in a wide range. Boron doped diamond shows high overvoltage for hydrogen and oxygen and allows electrochemical reactions in water without decomposing it. Diamond was deposited on glassy carbon and electro-graphite.
