焼結体に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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列にとつて説明する

なおさらのこと、実用化されるまでに到っていない。However, the spikes made by the above method are expensive because they use cemented carbide for the bottles and rings. In addition, drawbacks have been pointed out, such as high fuel consumption due to severe damage, high noise, and large damage to the road surface. As one way to overcome the above-mentioned disadvantages of using bottles 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. Furthermore, although zirconia-based ceramics have been studied because they have the highest toughness among ceramics, this study has not yet been sufficiently conducted. 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.

ことを見出したのである。High-strength colored zirconia consisting of one or more selected from OuO, (!u, , 0 and Coo) and CL1 to 6 weight coefficient, and having a specific gravity of 95% or more of the theoretical specific gravity calculated from the composition. It was discovered that the system sintered body provides the best characteristics as a colored ceramic for spikes, solving the problems of the conventional ones.

The reason for including it in the heavy weight sintered body is that if it is less than 11 weight, it will not be colored, and if it is more than 3 weight, it will inhibit sinterability and the strength will decrease significantly.

６９、実用化できる事を見い出したものである。In addition, for colored spikes, the zirconia-based sintered body has a theoretical specific gravity (the specific gravity of the compound to be mixed is calculated by the compound rule) of 95% or more, and the zirconia crystal phase is mainly tetragonal or It was discovered that a material that satisfies the condition of consisting of tetragonal and cubic crystals has sufficiently good strength properties69 and can be put to practical use.
理論比重が９５優未満では抗折力が低くスパイク性能が
良好でない。If the theoretical specific gravity is less than 95, the transverse rupture strength will be low and the spike performance will not be good.

As mentioned above, since the toughness is low, there is a high risk that an impact will be applied to the flange portion when it is driven into a tire and the flange portion will be damaged. Therefore, in conventional ceramic spikes as shown in FIG. 4 or 5, in order to prevent this, the flange portion must be protected by coating the flange surface with plastic or the like. That is the current situation. In contrast, in the case of spikes made of zirconia sintered bodies that have relatively higher toughness and are colored, such as those of the present invention, there is less risk of damage when driving them into tires. Therefore, as shown in FIG. 1, the entire sprue 1 including the flange portion 12 can be formed using this zirconia-based sintered body alone. Also, as other implementation columns,
As shown in Figure 2, there is a groove 15 near the mounting end of the spike 11.
A hole 14 is provided at one or more places, or a hole 14 is provided at one or more places as shown in FIG. It can also be configured by In such a case, the plastic part can be made thicker than the actual punching stopper, so the effectiveness of the punching stopper can be further increased.

い。Furthermore, since the volume of the spike portion is reduced, it can be made much lighter. Machining of grooves or holes in these zirconia sintered body spikes is easy if the zirconia sintered body is in an intermediate sintered state. In contrast, the ceramics that have been studied so far have low toughness, so if a groove or hole is provided in a part of the ceramic, stress concentration will occur.
There is a risk of damage starting at that part, so even if the flange is surrounded by plastic, its 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 low weight and have high practical value. In the present invention, in order to provide a groove or a hole in the vicinity of the attachment side end of the spike body made of zirconia sintered body and to join the plastic flange to that part,
The synthetic resin can be injected using the seven-lunge molding die, thereby filling the grooves and holes with the synthetic resin to prevent the flange portion from coming out.

のである。Although the present invention has been described above with respect to ceramic spikes for tires, the ceramic spikes of the present invention are not limited to use in tires, but can also be used in shoes with the same effect, and are not included in the present invention. It is something that will be done.
