A 10 mg sample is placed in an aluminum pan, held at 25°C for 10 minutes, and then heated to 600°C at a heating rate of 10°C / min. The temperature at which a 1% mass loss occurs from the initial mass is defined as the 1% thermal decomposition temperature.

[0068] To enhance adhesion, the material (a) may be degreased in advance, preferably by wiping with ethanol or isopropyl alcohol or ultrasonic cleaning, though not particularly limited thereto. Pretreatments include roughening the surface by sandblasting or the like, or by chemical conversion treatment such as alumite treatment, or by plasma treatment or corona treatment, and plasma treatment or corona treatment is particularly preferred.

[0069] The material (a) may be surface-treated with any known method to enhance adhesion, although this is not particularly limited. Specifically, the material may be treated with a silane coupling agent, such as an epoxysilane, aminosilane, isocyanatesilane, vinylsilane, acrylicsilane, hydrophobic alkylsilane, phenylsilane, or fluorinated alkylsilane, which has a reactive functional group.

[0070] Examples of the silane coupling agent include epoxy silanes such as γ-glycidoxypropyltriethoxysilane and β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, amino silanes such as aminopropyltriethoxysilane and N-phenylaminopropyltrimethoxysilane, isocyanate silanes such as 3-isocyanatepropyltrimethoxysilane, vinyl silanes such as vinyltrimethoxysilane, and acrylic silanes such as acryloxytrimethoxysilane, with 3-aminopropyltriethoxysilane, vinyltrimethoxysilane, and 3-methacryloxypropyltriethoxysilane being preferred.

[0071] In this specification, the carbon material refers to a material containing carbon, and preferably contains at least one selected from the group consisting of fullerene, carbon nanotube, graphite, amorphous carbon, and hydrogen-free carbyne. The carbon material can be any material that can form a carbon-containing coating on the surface of material (a) without any particular limitations.

Examples of PVD include sputtering, arc ion plating, ion vapor deposition, ion beam, and laser ablation. Of these, CVD, sputtering, ion vapor deposition, and arc ion plating are preferred.

[0074] When a carbon film is formed by CVD, the source gas is, for example, C X H Y (C represents carbon, H represents hydrogen, and X and Y represent integers of 1 or more.) In this case, the carbon film may contain hydrogen atoms as impurity atoms. On the other hand, when a carbon film is formed by PVD, the carbon film often contains hydrogen atoms as impurity atoms. Therefore, a carbon-containing film formed by CVD or PVD may contain hydrogen atoms as impurity atoms.

[0075] The carbon-containing coating can also be formed by a composite surface treatment. The composite surface treatment is a technique in which two or more surface treatments are performed on a substrate (material (a)). By performing a composite surface treatment, it is possible to improve the properties compared to when a single surface treatment is performed.

[0076] As the composite surface treatment, for example, PHN (nitriding) and PH coating can be used to form a carbon film on a substrate (material (a)). For example, by using "PHN (nitriding)" and "PH coating (DLC)" as the composite surface treatment, it is possible to improve the adhesion of DLC. Note that nitriding is a technique for diffusing and penetrating nitrogen (N) into the surface of a substrate to harden the vicinity of the substrate surface, and PHN (nitriding) is a nitriding method that uses plasma in a vacuum. The PH coating is a technique for forming a film on a substrate using arc ion plating, sputtering, or the like, which belong to the PVD methods.
