A DEPOSITION METHOD WHICH COMPRISES PROVIDING AN ENCLOSURE WITH TWO CONNECTED PORTIONS, POSITIONING AT LEAST ONE MEMBER OF HIGH TEMPERATURE MATERIAL WITHIN A FIRST PORTION OF SAID ENCLOSURE, POSITIONING AT LEAST ONE MEMBER OF HIGH TEMPERATURE MATERIAL IN A SECOND PORTION OF SAID ENCLOSURE, MAINTAINING THE PRESSURE OF SAID ENCLOSURE BETWEEN ONE MILLIMETER OF MERCURY AND ATMOSPHERIC PRESSURE, HEATING AN UNSATURATED HYDROCARBON MATERIAL TO A TEMPERATURE IN THE RANGE OF 1300*C. TO 1700*C. TO DECOMPOSE SAID MATERIAL TO A CARBONACEOUS VAPOR, SUPPLYING SAID VAPOR TO THE FIRST PORITON OF SAID ENCLOSURE, DEPOSITING A PORTION OF SAID VAPOR AS AN ADHERENT HARD CARBON COATING ON SAID MEMBER WITHIN THE FIRST PORITON OF SAID ENCLOSURE, SUPPLYING THE REMAINING VAPOR TO THE SECOND PORTION OF SAID ENCLOSURE, AND DEPOSITING SAID REMAINING VAPOR AT A TEMPERATURE OF AT LEAST 200*C. BELOW THE INITIAL TEMPERATURE OF THE VAPOR IN SAID FIRST PORITON AS AN ADHERENT HARDER CARBON COATING ON SAID MEMBER WITHIN THE SECOND PORTION OF SAID ENCLOSURE.
