Abstract

Fast deposition of graphitic carbon layers by an expanding cascaded arc plasma was studied as a means for in situ repair of graphite erosion damage in the next step fusion reactor NET/ITER. Amorphous graphite was produced at rates of hundreds of nanometers per second on several square centimeters with an argon-hydrocarbon plasma. Crystalline graphite was produced at rates of 10-50 nm s/sup -1/ on several square centimeters by means of an argon-hydrogen-hydrocarbon plasma. Relations between the deposition parameters, morphology (from scanning electron microscopy) and Raman spectra were determined. Using laser thermal shock testing, the erosion resistances of the best crystalline coatings were determined at about 2 MJ m/sup -2/ (in a 10 ms pulse)
