[0069] Since the adjacent layers are formed by plating, and different substrates (such as metal, ceramic, glass, etc.) have different adhesion abilities to the carbonized boron plating film. At the same time, the cleanliness and roughness of the substrate surface also affect the adhesion effect, so in order to increase the adhesion, the adhesion area is increased by the limiting part and the fitting part 7. Since the limiting part is arranged along the surface edge of the base layer 1, the adhesion strength of the carbonized boron layer 2 during plating can be ensured to be sufficient.
