たりする問題があつた。 However, since such products have a multilayer structure in which the plastic base and the ceramic layer on the surface are bonded with the intermediate layer as a soot body, each layer has a tendency to separate due to different coefficients of thermal expansion, and strong mechanical force or Especially when shear stress is applied,
There was a problem that the wear-resistant layer on the surface peeled off from the base or was destroyed.

に分離してしまうという問題があつた。 In addition, a structure in which small ceramic balls are embedded in the surface layer of an elastic material such as rubber is also available.
Although it is described in Japanese Patent No. 120932, the portion of the ceramic body exposed on the surface of the base is extremely small, so no effect on wear resistance can be expected, and there is also the problem that it separates during operation.

つ形状に成形されている。 FIG. 1 shows a cross section of a plastic substrate 1 in which a small lump of ceramic material 2 is embedded. The buried ceramic material 2 in the form of a small lump is attached to the plastic base 1.
The exposed surface 3 is preformed to be smooth so as to create a smooth and integral surface with the surface of the plastic substrate 1 when embedded in the plastic substrate 1. At the same time, the buried part is covered with plastic base 1.
It is molded in a shape that has a locking part 4 that locks into and does not fall off.

Various cross-sectional shapes as shown in FIG. 1 can be made. Figure 1 a shows a trapezoidal cross-sectional shape that expands downward, b shows a hexagonal shape, and c shows the top exposed surface 3.
It is shaped so that it is wide and narrow at the bottom, and has a locking part 4. This case c is convenient for uniformly arranging the ceramic material 2 during manufacturing. FIG. 1d shows an example of a shape in which either side can be an exposed surface.

形状にすることができることは勿論である。 FIG. 2 shows details of the shape of the small-sized ceramic material 2 shown in FIG. 1 b and d. A and b correspond to the ceramic material 2 in the form of a small block b in FIG. 1, and c and d correspond to d in FIG. As shown in each figure, the same effect can be achieved whether the recesses on each surface are hemispherical or the bottoms are flat. Moreover, FIG. 2e shows a modification of FIG. 1d, and shows an example in which two recesses are provided on each surface. It goes without saying that the shapes are not limited to these specific examples, but can be combined to form any shape.

体の表面層に固定することができる。 As shown in FIGS. 1a to 1d, the ceramic material 2 for burial is formed in advance to have a certain exposed surface, so that the ceramic material 2 is precisely shaped to the ratio set on the surface of the completed plastic product. The exposed surface of the material 2 can be formed. Furthermore, since each small lump of ceramic material 2 has a portion that locks onto the plastic base 1, the ceramic material 2 can be arbitrarily dispersed in the necessary areas, and the exposed surface covers at least 30% of the plastic surface. Even with the covering, the buried ceramic material 2 in the form of a small lump can be fixed to the surface layer of the plastic substrate without providing any special adhesive layer.
