PIPE EMBEDDED STRUCTURE AND METHOD OF MANUFACTURING THE SAME |
摘要 |
A pipe embedded structure includes: a pipe made of a metal or an alloy, and having a periphery forming a circular shape; a base material made of a metal or an alloy, including a recessed portion having an inner wall on which a part of the periphery abuts and in which the pipe is fitted; and a deposited layer formed by accelerating powder formed of a metal or an alloy together with a gas in a state where the pipe is fitted into the recessed portion, and spraying and depositing the powder on surfaces of the pipe and the base material while maintaining a solid phase state of the powder, wherein a ratio h/R of a protruding amount h by which the pipe protrudes from the surface of the base material and a curvature R of the periphery is not smaller than 0.3 and not greater than 0.7. |

1. A pipe embedded structure comprising:
a pipe made of a metal or an alloy, and having a periphery forming a circular shape in a transverse section; a base material made of a metal or an alloy, comprising a recessed portion having an inner wall on which a part of the periphery abuts and in which the pipe is fitted; and a deposited layer formed by accelerating powder formed of a metal or an alloy together with a gas in a state where the pipe is fitted into the recessed portion, and spraying and depositing the powder on surfaces of the pipe and the base material while maintaining a solid phase state of the powder, wherein a ratio h/R of a protruding amount h by which the pipe protrudes from the surface of the base material and a curvature R of the periphery is not smaller than 0.3 and not greater than 0.7. |
