The technique of oxide ceramic coating has been investigated for the purpose of electrical insulation of high temperature metal pipes and reduction of permeation of hydrogen fuel from pipes installed in the fusion reactor. In this topic, we will create a specimen of metal substrate coated by an oxide ceramic (the film thickness is several hundred nm). Further, we will discuss and consider the characteristics of the film from observation of the surface and the cross section using an electron microscope and analyze the atom distribution.
