(3)PCVD (Plasma Chemical Vapor Deposition)

Ho sebelisa plasma ho khothaletsa karabelo ea lik'hemik'hale le ho fokotsa mocheso oa ho roala ka tlase ho 600 ° C. E loketse linako tseo karabelo kapa phapanyetsano e seng bonolo ho etsahala pakeng tsa substrate e entsoeng ka samente ea carbide le thepa ea ho roala.
