SELF-PROPAGATING BRAZE |
| 摘要 |
A method may include positioning a first ceramic or ceramic matrix composite (CMC)part and a second ceramic or CMC part adjacent to each other to define a joint between adjacent portions of the first ceramic or CMC part and the second ceramic or CMC part. The method also may include introducing a carbon-containing filler at the joint; introducing molten silicon-containing braze material at the joint; and allowing silicon metal from the molten silicon-containing braze material to react with the carbon-containing filler to form silicon carbide and join the first ceramic or CMC part and the second ceramic or CMC part at the joint. In some examples, no external heat source directly heats the joint during the reaction of the molten silicon-containing braze material with the carbon-containing filler. |

1. A method comprising:
positioning a first ceramic or ceramic matrix composite (CMC) part and a second ceramic or CMC part adjacent to each other to define a joint between adjacent portions of the first ceramic or CMC part and the second ceramic or CMC part; introducing a carbon-containing filler at the joint; introducing molten silicon-containing braze material at the joint; and allowing silicon metal from the molten silicon-containing braze material to react with carbon from the carbon-containing filler to form silicon carbide and join the first ceramic or CMC part and the second ceramic or CMC part at the joint, wherein no external heat source directly heats the joint during the reaction of the molten silicon-containing braze material with the carbon-containing filler. |
