料、電極などに適用されている。 On the other hand, with regard to applications, we target ready-made materials and shapes such as ceramics, metals, and carbonaceous materials as base materials on which carbon is deposited, and coat the surface of this material with carbon to modify the function of the material. It is thought that the precipitated layer can be taken out individually and used as a new material, and used for various purposes in the form of a single substance or a composite, and some of them have entered the stage of practical application. For example, it is applied to biological materials, spacecraft materials, mechanical materials, electrodes, etc.

The essence of this reaction is that carbon deposition occurs in the gas phase, and this combined with high-temperature treatment makes it difficult to process many substrates at once in the same reactor or to process products with complex shapes. This has been extremely difficult industrially, especially in ensuring product uniformity.

The gist is a method in which pyrolytic carbon is deposited on a substrate by induction heating under the flow of a raw material gas to precipitate pyrolytic carbon, in which multiple substrates are supported in multiple stages within a reactor. The reactor is characterized in that the raw material gas is simultaneously supplied to each stage through an introduction pipe provided along the inner wall of the reactor and branch pipes extending from this introduction pipe toward each stage of the multi-stage supporting the above-mentioned substrate. The invention consists in a method of depositing pyrolytic carbon on a substrate.

冷媒を通すのがよい。 Although the reactor main body 1 is not shown, it is preferable to provide a cooling jacket and cool it by passing water through it during the reaction process. Further, although the raw material gas introduction pipe 6 and the branch pipe 6' may be a single pipe, it is preferable to use double pipes to pass a refrigerant such as water.

Then, the base material 5 is placed on each frame 3, and the base material 5 is heated to a desired temperature by the induction coil 2, and at the same time, the raw material gas is introduced into the inlet pipe 6.
will be sent from. The raw material gas comes into contact with the base material on each pedestal through the branch pipe 6', and deposits carbon on the base material. Since the base material is in contact with the raw material gas from the branch pipe 6' branching out for each stage, it is always treated with unused raw material gas, and therefore the base material on the frame of any stage is always constant. undergoes uniform carbon deposition.

However, the low-temperature pyrolysis method using the above-mentioned halogenated hydrocarbon as the raw material gas is preferred from the viewpoint of ease of selection of reactor material, operability, and ease of precipitation.

に多数の基材への析出を高温で実施することは技
術上、極めて困難である。 As described above, according to the method of the present invention, pyrolytic carbon can be precipitated industrially very advantageously. That is, in the conventional method, the base material is placed in a reactor isolated from the outside world, and pyrolytic carbon is deposited on the base material by heating the entire base material while supplying raw material gas to the reactor. According to this conventional method, when carbon is deposited on a plurality of base materials, as the number of base materials increases, it is unavoidable that the reactor and eventually the heating device become large. In addition, as the number of substrates to be treated increases and the reactor becomes larger, the concentration, composition, flow rate, etc. of the raw material gas change locally within the reactor, resulting in changes in the quality of the pyrolyzed carbon that precipitates. It is inevitable that the differences and deposition rates will differ, and it is technically extremely difficult to perform deposition on a large number of substrates at high temperatures at the same time under the same conditions.
これに対し、本発明方法では、基材は反応ガス
流に沿つて多段に設置されるので、反応器の空間
を有効に利用することにより加熱装置を格別大き
くする必要がない。 On the other hand, in the method of the present invention, the substrates are installed in multiple stages along the flow of the reactant gas, so the space in the reactor is effectively utilized, so there is no need to make the heating device particularly large.

で、下流域においても未分解の原料ガスに接し、
均一な熱分解炭素を析出させることができる。 Furthermore, if the base material is simply installed in multiple stages and the raw material gas is introduced from one end, the effective gas component to be thermally decomposed decreases in the downstream region of the gas, making it possible to deposit uniform pyrolytic carbon in the upstream and downstream regions. become unable.
According to the method of the present invention, even if the base material is installed in multiple stages,
Since the raw material gas is supplied near the base material through branch pipes, it comes into contact with undecomposed raw material gas even in the downstream region.
Uniform pyrolytic carbon can be deposited.

材上に熱分解炭素を析出させる方法。1. In a method in which pyrolytic carbon is deposited on a substrate by direct induction heating of the substrate under the flow of a raw material gas to precipitate pyrolytic carbon, a plurality of substrates are supported in multiple stages in a reactor and the reaction is carried out. A base characterized in that raw material gas is simultaneously supplied to each stage through an introduction pipe provided along the inner wall of the vessel and branch pipes extending from this introduction pipe toward each stage of the multi-stage supporting the base material. A method of depositing pyrolytic carbon on materials.
