Abstract:
According to the present invention, a structure made of yttrium oxide is formed on a surface of a substrate comprises yttrium oxide polycrystals as a main component, a boundary layer made of hyaline does not substantially exist on a boundary face between crystals which form the structure, and both a cubic system and a monoclinic system exist in the crystal system of the yttrium oxide polycrystals. With this, it is possible to adjust the hardness of the structure made of yttrium oxide formed on a surface of a substrate to be larger than that of an yttrium oxide sintered body.
