[Field of Industrial Application] The present invention relates to an adhesive used for bonding ceramics together or bonding ceramics and metals. [Conventional technology] Fine ceramics have excellent heat resistance, thermal shock resistance,
Because it has excellent corrosion resistance and mechanically and chemically stable physical properties, it is currently attracting attention for its use in a variety of fields, including electronic and mechanical parts. However, ceramics generally have poor machinability, which often causes problems in molding and assembly, thus hindering their application. Therefore, establishing the adhesive technology is an important issue. Conventionally, hot pressing methods and brazing methods using high-melting point metals have been known as main methods for bonding ceramics to ceramics or ceramics to metals. The former method involves diffusion bonding of ceramic interfaces under high temperature and high pressure, and may also include bonding by sandwiching base material powder at the interface. On the other hand, for the latter, fine powder such as Mo or Mo-Mn is applied onto ceramics, metallized at a temperature of 1300 to 1700°C in humidified hydrogen or humidified forming gas, and then nickel plated on top of this, and then used as a brazing material. This is a method of bonding using Ag-Cu alloy, Ag-Pd alloy, etc. (Japanese Patent Laid-Open No. 161978/1983). [Problems to be Solved by the Invention] However, the above adhesive method has the following problems. In other words, although it is known that a bonded body with high strength can be obtained by the hot press method, on the other hand,
When bonding, the ceramics etc. cause creep deformation, which tends to cause molding defects in the bonded portion and the base material, and there is also the problem that incidental equipment such as press equipment becomes larger.
In addition, brazing with high-melting point metals requires heating to a considerably high temperature in order to obtain a strong joint, and also requires the use of a large amount of brazing filler metal whose main component is noble metal. The complicated bonding process has the disadvantage of increasing costs. In view of these problems, the present invention provides a new ceramic adhesive that can easily and inexpensively bond ceramics together or ceramics and metals. [Means for solving the problems and their effects] The ceramic adhesive of the present invention basically has the following features:
The main components are boron oxide (B 2 O 3 ), manganese oxide, and cobalt oxide, and depending on the adhesion mode and conditions, other oxide components described below may be added and used. Manganese oxide is
It is preferable that MnO and cobalt oxide take the form of CoO, but other oxide forms are also acceptable. Among the adhesive components, B 2 O 3 and MnO form the skeleton of the overall structure in the adhesive layer between the objects to be joined. In particular, MnO diffuses into the ceramics or metals to be bonded, strengthening the adhesive strength. Furthermore, when bonding ceramics and iron-based alloys, CoO causes electrochemical erosion with Fe (Fe+Co 2+ →Co+Fe 2+ ) to strengthen the adhesive force. The mixing ratio of B 2 O 3 and MnO can be selected within a wide range, but it is adjusted so that the coefficient of thermal expansion of the adhesive layer approximates that of the adherend. If the objects to be adhered are different, the thermal expansion coefficient is adjusted to be intermediate between the two. Further, CoO is sufficient at 10% by weight or less, and the content within this range is sufficient to exhibit the effect. In addition to the main components described above, the following oxides can be further added to the adhesive of the present invention as needed. Aluminum oxide (Al 2 O 3 ) is effective in increasing the strength of the adhesive, and its addition is effective when the strength of the adhesive is insufficient when only the main component is blended. In addition, its content is 5 to 15% by weight. Also, oxides of group IA elements, such as K 2 O, Na 2
O etc. are effective components for adjusting the thermal expansion coefficient of the adhesive, and when it is necessary to obtain the desired thermal expansion coefficient even if the main component ratio (B 2 O 3 /MnO) is changed, Addition becomes effective. That is, by containing one or more of these oxides, it can be used for bonding a wider range of ceramics and the like. Furthermore, especially when the ceramic to be bonded is zirconia, it is preferable to include a stabilizer thereof (such as Y 2 O 3 ). Zirconia ceramics contains a stabilizer to prevent phase transition, but depending on the temperature during bonding or during use, the stabilizer in zirconia may diffuse into the adhesive and become depleted. . In order to suppress the diffusion of such stabilizers and prevent strength deterioration, adhesives are
It is preferable to pre-include 0.1 to 10% by weight of a stabilizer. The ceramic adhesive of the present invention is a powder consisting of a mixture of the above-mentioned essential main components and optional components. When bonding ceramics together or ceramics and metals (mainly iron-based alloys) using the adhesive of the present invention, it can be applied to the surface of one base material either in powder form or by using an organic binder. After applying the adhesive, the other base material may be placed on top of the adhesive and heated to a temperature higher than the melting point of the adhesive (approximately 800 to 1200°C).
At this time, slight pressure may be applied to improve the adhesion between the object and the adhesive. Further, the atmosphere during bonding is preferably adjusted to a neutral or reducing gas or vacuum in order to prevent oxidation of the metal to be bonded. [Example] Below, test results when zirconia was bonded using the adhesive according to the present invention are shown. However, and are examples of adhesion between zirconia and carbon steel, and are examples of adhesion between zirconia.

When compared with conventional bonding methods, it has the following advantages. That is, since high temperature and high pressure are not required, deformation of the base material etc. is not caused, and additional equipment and equipment can be simple. Furthermore, compared to expensive brazing filler metals, the present adhesive is inexpensive, and the coefficient of thermal expansion can be approximated to that of the adherend, so the bonding strength can be increased.
