Abstract

Fast deposition of graphitic carbon layers by an expanding cascaded arc plasma has been 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 nm/s on several cm2 with an argon/hydrocarbon plasma. Crystalline graphite was produced at rates of 10-50 nm/s on several cm2 by means of an argon/hydrogen/hydrocarbon plasma. Relations between the deposition parameters, morphology (by SEM) and Raman spectra have been determined. By laser thermal shock testing, the erosion resistance of the best crystalline coatings was determined at about 2 MJ/m2 (in a 10 ms pulse).
