Hydrogenated amorphous carbon or diamondlike carbon (DLC) films were formed by 400 eV methane (CH4) ion bombardment of various smooth and rough ceramics, as well as ceramics coated with a layer of Si or Ti. Adhesion was measured by a bonded‐pin method. Excellent adhesion was measured for smooth SiC and Si3N4, but adhesion of DLC to smooth Al2O3 and ZrO2 was negligible. The use of a Si bonding interlayer produced good adhesion to all the substrates, but a Ti layer was ineffective due to poor bonding between the DLC film and Ti. Bulk thermodynamic calculations are not directly applicable to bonding at the interface because the interface is two dimensional and the compositions of interfacial phases are generally not known. If the standard enthalpy ΔH° for the reaction between CH4 and the substrate material is calculated under the assumption that a carbide phase is produced, a relationship is seen between the reaction enthalpy and the relative adhesion. Large positive enthalpies are associated with poor adhes...
