必要である。 A thermal spray coating using this thermal spray material has a structure in which ceramic particles are melted and laminated to form pores filled with a glass phase having a low melting point and low viscosity. One of the characteristics is that the ceramic phase and the glass phase are separate phases. For this purpose, the ceramic material must have a high melting point, and the glass material must have a low melting point. If the difference in melting point between the two is small, there is a risk that the two will fuse and become a homogeneous phase, causing the characteristics of the ceramic coating to be lost. The glass phase fills the pores and therefore needs to have a low viscosity.
