焼結体に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a colored zirconia yarn sintered body that can be used, for example, in anti-slip spikes for shoes, tires, etc.
以下タイヤ用セラミックスノくイクをガにとって説明す

ている。Conventionally, spikes for snow tires for use on snow and ice have been made by brazing or brazing a cemented carbide metal bottle 2 or a cemented carbide ring 6 to a steel shank 1 as shown in FIGS. 4 and 5. Items that are joined using methods such as caulking are called kanji.

用化されるまでには至っていない。However, the tomo spike made by the above method is expensive because it uses cemented carbide for the bottle and ring. In addition, drawbacks have been pointed out, such as high fuel consumption due to heavy weight, high noise levels, and large damage to road surfaces. As a way to eliminate the above-mentioned disadvantages of using cemented carbide bottles and rings, the use of alumina-based ceramics in place of cemented carbide has recently been investigated. 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.

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.

It was discovered that the colored zirconia-based sintered body of III layer provides the best characteristics as a color-enhancing ceramic for spikes, eliminating the problems of conventional products.

It is something that If the theoretical specific gravity is less than 9a5%, the transverse rupture strength will be low and the spike performance will not be good.

うのが現状でおる。First, as mentioned above, conventional spikes made of ceramic alone have low toughness, so there is a high risk that the flange will be damaged by impact applied to it when it is driven into the tire. Therefore, in order to prevent this from occurring in conventional ceramic spikes as shown in Figures 4 and 5, the current situation is that the flange surface must be protected by coating it with plastic, etc. I'll go.

性はよくない。On the other hand, in the case of spikes made of zirconia sintered bodies such as those of the present invention (AttO), which have relatively higher toughness and increased color, there is a risk of damage when driving them into tires. As shown in FIG. 1, the entire spike 11 including the flange portion 12 can be made of gold using this zirconia-based sintered body alone, as shown in FIG. By providing one or more holes 14 in the vicinity of the mounting side end of 11, or by providing holes 14 in one or several places as shown in Fig. 3, the effect of preventing removal is provided. It is also possible to construct the part by surrounding it with a flange 15 on the plastic surface.In this case, the thickness of the plastic part can be made larger than when using a protrusion to prevent removal, so the effect of the removal prevention can be improved. It can be made even larger.Furthermore, the volume of the spike part can be made smaller to reduce the volume.Processing such as rounding or holes in these zirconia sintered spikes can be done using zirconia sintered material. This is easy if the body is intermediately sintered.On the other hand, 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, and the Therefore, even if the flange part is surrounded by plastic, its durability is not good.

を表１に併せて示す。Ｎｏ。As described above, by using the zirconia sintered body of the present invention as a material, it is possible to obtain spikes for snow tires that have high strength and low weight and are of high practical value. In this invention, in order to provide a groove or a hole in the vicinity of the mounting end of the snook body made of zirconia sintered body, and to join the plastic 7 flange to that part, the flange topography metal m The synthetic resin can be injected using a 500-degree flange, and the synthetic resin can be embedded in the grooves and holes to prevent the 1n5 flange from coming out. Although the ceramic spikes for tires have been described above, the ceramic spikes of the present invention are not limited to tires, but can also be used for shoes with the same effect. 0 [Implementation example] Using sintered bodies with various compositions shown in Table 1, spikes of the shape shown in Figure 5 were prepared, and the transverse rupture strength (y/n) and fracture toughness (
