パイク用等に使用できる着色された高強度ジルコニア系
焼結体に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a colored high-strength zirconia-based sintered body that can be used, for example, as anti-slip spikes for shoes, tires, and other devices.
以下タイヤ用セラミックスパイクを岡にとって説明する
が、シューズ特にスポーツ用等についても全く同様であ
る。The following explanation will focus on ceramic spikes for tires, but the same applies to shoes, especially for sports shoes.

いられている。Conventionally, spikes for snow tires for use on snow and ice include a steel shank 1 and a cemented carbide pin 2 or a cemented carbide ring 3t-.

く実用化されるまでには至っていない。However, the spikes made by the above method are expensive because they use cemented carbide for the pins and rings. In addition, disadvantages have been pointed out, such as high fuel consumption due to the large weight, high noise, and large damage to the road surface. As a way to overcome the above-mentioned drawbacks of the pins and rings made of cemented carbide, the use of alumina-based ceramics in place of cemented carbide has recently been considered. However, alumina-based ceramics have low toughness and have a high risk of causing accidents such as chipping and breakage, so they have not been put into practical use.

なおさらのこと、実用化されるまでに到っていない。Furthermore, although zirconia ceramics have been studied because they have the highest toughness among ceramics, this study has not been sufficient yet. By the way, conventional zirconia ceramics are white or black, but as a recent trend, these spikes are also required to be decorative. However, due to the current situation as mentioned above, colored zirconia ceramics are
What's more, it has not yet been put into practical use.
本発明はこのような事情に鑑みて従来品の欠点を解消し

A high-strength colored zirconia-based sintered body having a specific gravity of 95% or more of the theoretical specific gravity calculated from the composition, consisting of one or two or more selected from a1l and Th and 11 to 3 weights, They have discovered that they can obtain the best characteristics as colored ceramics for spikes, solving the problems of the conventional ones.

If O3 and/or Coo are less than the lower limit of the above range, metastable tetragonalization will be insufficient and defects such as cracking during manufacturing will not be eliminated; This is because the amount of appearance increases and the intensity decreases.

The reason why the sintered body contains more than 1 L of seeds is as follows:
If IIL is less than 1%, no coloration occurs, and if IIL exceeds 1%, sinterability is inhibited and the strength is significantly reduced.
In addition, for colored spikes, the zirconia-based sintered body must have a theoretical specific gravity (calculated from the composite material of the compound to be mixed) of 95% or more, and the zirconia crystal phase should be It has been discovered that a material that satisfies the condition that it is mainly composed of tetragonal crystals or tetragonal crystals and cubic crystals has sufficiently good strength characteristics and can be put into practical use.

As mentioned above, since the toughness is low, there is a high risk of damage to the flange due to impact applied to the flange when driving into a tire. Therefore, Fig. 4 or 5
In order to prevent this from occurring in conventional ceramic spikes as shown in the figure, the current situation is that the flange must be protected by coating the surface of the flange with plastic or the like.

、その耐性はよくない。On the other hand, in the case of spikes made of colored zirconia sintered bodies, which have relatively higher toughness than Mu40s, as in the present invention, there is less risk of damage when driving them into tires. , as shown in Figure 1,
The entire task spike 11 including the flange portion 12 can be formed using this zirconia-based sintered body alone. In addition, as another example, as shown in FIG.
Alternatively, as shown in FIG. 3, it is also possible to create a p structure by providing one or more holes 14 to provide a pull-out prevention effect and surrounding those portions with plastic 7 langes 15. . In such a case, the thickness of the plastic part can be made larger than that in the case where the protrusion prevents removal, so the effect of the removal stop can be further increased. Furthermore, since the volume of the spike portion is reduced, it can also be made lighter. Machining of grooves or holes on these zirconia sintered spikes is done by
This is easy if the zirconia sintered body is intermediately sintered. In contrast, the ceramics that have been studied so far have low toughness, so if a groove or hole is formed in a part of the ceramic,
Stress concentration occurs and there is a risk of breakage from that part, so even if the 7 langes are surrounded with plastic, the durability is not good.

る。As described above, by using a zirconia sintered body as a material as in the present invention, it is possible to obtain spikes for snow tires that have high strength and high resistance and are small in weight and have high practical value. In the present invention, in order to provide a groove or hole in the vicinity of the attachment side end of the spike body made of zirconia sintered body and to join the plastic 7 flange to that part,
The synthetic resin can be injected using the 7-lunge molding mold, and the synthetic resin is thereby embedded in the grooves and holes, thereby achieving the effect of preventing the 7-lunge portion from coming out.

It is something that will be done.
