SEALANT, SEALANT COATING LIQUID, CORROSION RESISTANT FILM, HIGH TEMPERATURE MEMBER, AND PRODUCTION METHOD OF HIGH TEMPERATURE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a sealant capable of sealing pores on a corrosion resistant film for a long period, and preventing corrosion of a substrate.;SOLUTION: There is provided a sealant 1 for sealing pores on a corrosion resistant film 2, which is a sealant 1 comprising a mixture of glass in which the ratio of alkali metal oxide occupying a glass composition is 20 mass% or less, and a non-alkaline boron compound. In the sealant 1, the glass is ZnO-B2O3-based glass, and the ratio of the non-alkaline boron compound occupying the sealant 1 is 5-70 mass%. A corrosion resistant film 2 contains one or more kinds selected from ZrO₂, Al₂O₃ or SiO₂ as much as 50 mass% or more.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
