Document Type and Number:
Japanese Patent JP5778711
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for attaining improvement of durability by suppressing diffusion of Cr by forming a more uniform and dense protective film than conventional ones.SOLUTION: A manufacturing method of an inter-cell connection member for forming a protective film from a metal oxide over a base material formed from an alloy or an oxide containing Cr and Mn includes: a coating forming step of forming a non-sintered coating containing metal oxide fine particles as a main component on the base material; a calcination step of calcinating the coating under a condition that Mn contained in the base material reacts with a coating component; and a step of forming a dense layer which is generated by reacting the coating component and Mn, within the coating adhesively with a CrOlayer formed on a surface of the base material and growing the dense layer to thickness of 1 μm or more.
