A ceramic matrix composite component includes a first substrate and a second substrate each formed of a silicide-containing ceramic matrix composite, silicon carbide layers respectively coating a bonding surface of the first substrate and a bonding surface of the second substrate, and a bonding layer formed of a silicon-containing alloy and provided between the silicon carbide layer coating the bonding surface of the first substrate and the silicon carbide layer coating the bonding surface of the second substrate.

Ceramic matrix composite component and method of producing the same

A welding method of a diffusion bonded structure in which the diffusion bonded structure formed by diffusion bonding metal parts to each other is bonded to another part by fusion welding includes a buffer layer forming step of forming a buffer layer in a welding region including a diffusion bonded joint of the diffusion bonded structure, the buffer layer having greater ductility than the diffusion bonded joint, and a welding step of bonding the welding region in which the buffer layer is formed to the another part by performing the fusion welding from above the buffer layer.

Welding method of diffusion bonded structure

An end surface of each first side wall, an end surface of each first middle wall, and an end surface of each first end wall are joined to an adjacent second structure by diffusion bonding, an end surface of each second side wall, an end surface of each second middle wall, and an end surface of each second end wall are joined to an adjacent first structure or a lid structure by diffusion bonding, a thickness of each first side wall is greater than or equal to a thickness of each first middle wall, and a thickness of each second side wall is greater than or equal to a thickness of each second middle wall.
