TL;DR: In this article, a chip plug 56 is mounted on and fitted to the seat part 55a of a used hole 55 which is formed on the top 52 of the gas turbine blade and from which a core or the like is taken out, and then the butted parts T are welded by forming the butt welding parts 57 using YAG laser beam, thus closing the used hole with the chipplug 56.

TL;DR: In this article, a heat treatment method for a Ni-based alloy employed for a high-temperature component such as a gas-turbine and a jet engine, is characterized by heat treating a base metal made from the Nibased alloy in such a high temperature that γ' phase with diameters of 0.3-0.5 μm precipitates in the surface layer part of the base metal, before subjecting it to a normal heat treatment at a solution temperature of the γ'' phase or a higher temperature.

TL;DR: In this paper, a thermal spraying equipment for a method for reusing thermal spray coating powder was proposed, which includes: a recovering apparatus 30 for recovering a powder including MCrAlY thermal spray and YSZ thermal spraying coating powder.

TL;DR: In this paper, a Ni-based heat resistant alloy was used to provide a repaired high-temperature component made of a Nibased heat-resistant alloy, which consists of a base substance of the high-Temperature component, and a repaired part of the higher temperature component that does not cause hot cracking and has the same level of superior high temperature strength.

TL;DR: In this paper, a Co group alloy laminated shaped body is presented as a composite material having mechanical characteristics equivalent to a precipitation strengthening Ni group alloy material, and a method for manufacturing them is presented.
