The 3rd, 4th, 5th, 6th and so on.

First, it has excellent wear resistance. That is, the ceramic sprayed film 5 having a hardness equal to or higher than that of metal is formed on the surface of the surface plate 3. Therefore, this honeycomb surface plate has a high surface hardness, and the surface is unlikely to wear even when an object as a friction partner is placed on and brought into contact therewith.

Secondly, it has high heat resistance. That is, the ceramic sprayed film 5 having higher heat resistance than metal is formed on the surface of the surface plate 3. Therefore, this honeycomb surface plate has high heat resistance on the surface.

Thirdly, it is not easily scratched. That is, as described above, the ceramic sprayed film 5 having hardness and heat resistance higher than that of metal is formed on the surface of the surface plate 3. Therefore, this honeycomb surface plate has high surface hardness and little surface oxidation,
Even if an object is placed on it and in contact with it, there are few scratches on the surface.

Fourth, it is lightweight and has excellent strength. That is, the honeycomb core 2 is used as a core material, and the surface plate 3 is composed of a thin metal plate 4 and a ceramic sprayed film 5. Therefore, this honeycomb surface plate is lightweight as a whole by utilizing the characteristic of the honeycomb core 2 that is excellent in weight-specific strength, and a predetermined strength required for the load by the object is secured.

And the honeycomb core 2 is
It is composed of a planar aggregate of cells 1 in the shape of a hollow column, and its cell end surface is an open surface, which cannot be such a thermal spray target, and of course some thermal spray target is required.
