Abstract
A joined body 20 includes a first member 21, a second member 22, and a joint portion 30 which is formed from an oxide ceramic containing a Fe3O4 phase in which a solute component capable of forming a spinel-type oxide with Fe is solid-dissolved and which joins the first member 21 and the second member 22.
Claims21
A joined body comprising:
- a first member;
- a second member;
- and
- a joint portion which is formed of an oxide ceramic containing a Fe3O4 phase in which a solute component capable of forming a spinel-type oxide with Fe is solid-dissolved and which joins the first member and the second member.
1 more element
A method for manufacturing a joined body in which a first member and a second member is joined to each other, the method comprising:
- a step of forming a laminate in which between the first member and the second member, a joint layer including a Fe metal powder and a solute component powder which contains a solute component capable of forming a spinel-type oxide with Fe;
- and a joining step of firing the laminate in a temperature range lower than the melting point of a Fe oxide to form an oxide ceramic functioning as a joint portion which joins the first member and the second member.
A method for manufacturing a joined body comprising:
- a thermal spraying step of melting a raw material powder including a Fe raw material powder which contains at least one of a Fe metal powder and a Fe oxide powder and a solute component powder which contains a solute component capable of forming a spinel-type oxide with Fe, and thermal spraying the melt to form a joint portion which joins a first member and a second member adjacent thereto and which is formed of an oxide ceramic containing a Fe3O4 phase in which the solute component is solid-dissolved.
