適用することができる。[Industrial Application Field] The present invention relates to a novel method for manufacturing a vapor-phase synthetic diamond tool. More specifically, the present invention relates to a method for efficiently manufacturing vapor-phase synthetic diamond tools, such as cutting tools and wear-resistant tools, in which a vapor-phase synthetic diamond thin film is firmly adhered to a substrate. [Prior Art] Conventionally, tools for cutting non-ferrous and non-metallic materials or wear-resistant tools that require high wear resistance include cemented carbide, polycrystalline sintered diamond, and natural or synthetic single-crystal diamond. It is used. Among these, diamond tools have characteristics such as high hardness, high wear resistance, and excellent adhesion resistance with work materials, so they can be used for cutting tools such as cutting tools, indexable tips, drills, and end mills. It is used as wear-resistant tools that require hardness and wear resistance. On the other hand, diamond synthetic leather technology has made remarkable progress in recent years.
New attempts have been made to deposit a diamond thin film by vapor phase synthesis on a metal tool substrate or a cemented carbide tool substrate and apply it to cutting tools and wear-resistant tools. However, in the conventional manufacturing method of vapor-phase synthetic diamond tools, diamond films are difficult to deposit on iron-based metal substrates, are greatly affected by the type of substrate, are subject to limitations of the substrate material, and are difficult to form. The adhesion between a diamond film and a tool base is not necessarily strong; for example, cutting tips in which a diamond film is provided on a cemented carbide base have drawbacks such as the diamond film peeling off during cutting. Thus, the reality is that no practical tool equipped with a vapor-phase synthetic diamond film has been found so far. [Problems to be Solved by the Invention] The present invention overcomes the drawbacks of the conventional method for producing a vapor-phase synthetic diamond tool, and can produce a vapor-phase synthetic diamond film without being restricted by the type of tool substrate. The object of the present invention is to provide a vapor-phase synthetic diamond tool which is firmly bonded to a tool base. [Means for Solving the Problems] As a result of extensive research to achieve the above object, the present inventors have previously provided a brazing material layer on the surface of a substrate, on which diamonds tend to precipitate, and then It was discovered that the object could be achieved by precipitating diamond in the form of a film using a vapor phase synthesis method and then melting the brazing material layer, and based on this knowledge, the present invention was completed. That is, in the present invention, after providing a brazing material layer on the surface of a tool base, diamond is deposited in the form of a film on the surface by vapor phase synthesis, and then the brazing material layer is melted to bond the base material and the diamond film. The present invention provides a method for manufacturing a vapor-phase synthetic diamond tool, which is characterized by bonding. The present invention will be explained in detail below. In the method of the present invention, a brazing material layer is first provided on the surface of the tool base. This brazing material has good wettability with the substrate and easy precipitation of diamond, and is 600°C or higher, which is the usual vapor phase synthesis temperature for diamond, preferably 600 to 1300°C, more preferably 800 to 11°C.
There is no particular restriction as long as it has a melting point of 00°C. As such a brazing material, for example, Au-N
Examples include gold thread brazing materials such as 1-Cu series, Au-Cu-Ag series, Au-Ni-Cr series, and Au-Ta series, and other silver thread brazing materials.
90% by weight gold thread brazing material is preferred. These brazing materials are appropriately selected depending on the type of tool base to be used. There are no particular restrictions on the method of providing a layer made of these brazing materials on the surface of the substrate; for example, the brazing material is melted and cast on the surface of the substrate, and then the surface of the brazing material is polished to a thickness of about several tens of micrometers. A method of finishing a brazing material layer to a uniform thickness on the substrate surface, or by applying a physical vapor deposition method (PVD method) such as a vacuum evaporation method, ion blasting method, sputtering method, or plasma method, or a chemical vapor deposition method (CVD method) ), any method can be selected and used, such as a method of forming the film to a thickness of about several tens of μm. Among these methods, when the substrate surface has a curved surface or a complicated shape, it is advantageous to provide the brazing material layer by PVD or CVD. In the method of the present invention, diamond is then deposited in the form of a film with a thickness of usually 1 to 1000 μm by vapor phase synthesis on the brazing material layer thus provided on the surface of the tool base. If the thickness is less than 1 μm, cracks and breakage will easily occur during use, and if it exceeds 1000 μm, there will be no improvement in performance as a tool considering the thickness, but rather it will take too much time to form the coating, making it more efficient. This is undesirable as it causes a decrease in There are no particular restrictions on the method for depositing the diamond film on this brazing material layer, and methods commonly used as the conventional diamond film phase elongation method, such as pyrolysis CVD, plasma CVD, ion beam CV
A chemical vapor deposition method such as the D method or a physical vapor deposition method can be employed. Next, the substrate on which the diamond film is provided with the brazing material layer interposed in this manner is heated in a vacuum to melt the brazing material layer and firmly adhere the diamond film to the substrate. The method of the present invention can be applied, for example, to the production of cutting tools such as cutting tools, throw-away tips, drills, and end mills, as well as wear-resistant mechanical parts and jigs that require hardness and wear resistance.
