【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、可撓性を有する溶射用線材に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a flexible wire for thermal spraying.

て作業はできず、溶射効率も好ましくない。Thermal spraying of ceramic or metal granules involves supplying the powder or granules to the tip of the nozzle of a thermal spray gun, and melting and spraying the powder or granules onto the object to be sprayed using a high-temperature jet stream emitted from the spray gun. In this case, a device is required to supply the powder or granules that are the thermal spray material to the thermal spray gun, and it is not possible to work remotely from the device, and the thermal spraying efficiency is also unfavorable.
こうしたことから、粉・粒体に代えてそれらを棒状にし

きない等の問題がある。For this reason, instead of powder and granules, rod-shaped products are manufactured by Two-Tone in the United States under the trade name rROKII').
It is supplied as EJ. This is made by firing ceramic powder into a rod shape, and because it is not flexible, it cannot be manufactured into long lengths and wound into bobbins or coiled. , there are problems such as not being able to work continuously.
本発明は、以上の点に留意し可撓性を有する溶射用線材
を提供することを目的とする。The present invention takes the above points into consideration and aims to provide a flexible wire for thermal spraying.
上記目的を達成するため、本発明の溶射用線材にあって

け、水分を揮散せしめたものとしたのである。In order to achieve the above object, the wire rod for thermal spraying of the present invention includes a thermal spraying material made of powder or granules of ceramic, metal, or both, a binder, and an anti-drying agent (hereinafter referred to as an anti-drying agent). A paste-like core material made of a paste-like core material kneaded with water is coated on the outer periphery of the core with a base-like outer covering made of a binder and a desiccant material kneaded with water, or a coating is provided. It was made to volatilize moisture.

溶射効率も向−Ｌする。In the thermal spraying wire of the present invention configured as described above,
Powders and granules are bound together with a binder such as a cellulose derivative, and the bound mixture [1] Yuko contains an appropriate amount of desiccant agent, such as glycerin, so that the water added during kneading does not evaporate. It also has appropriate hardness and flexibility, and can be wound into a bobbin or coiled to produce and supply long powder/granular thermal spray wire +4. Therefore, during thermal spraying, long linear thermal spraying materials wound in bobbins or coils can be continuously supplied to the thermal spraying gun, allowing continuous work for long periods of time, improving work efficiency, and reducing restrictions on thermal spraying locations. Thermal spray efficiency is also improved.

宜選択決定すればよい。In addition, in the present invention, water is used to knead the material of the mixture,
The amount that can be effectively formed when forming the mixture into a linear shape may be appropriately selected and determined.

ニアとによって安定な硬い溶射面を得ることができる。Here, magnesia, calcia, and ittria are often used as stabilizers for sprayed surfaces, and for example, a stable and hard sprayed surface can be obtained by using zirconia and arconia.
また、共晶セラミックを用いる場合は単体より低い融点
のものを得ることができる。Furthermore, when using a eutectic ceramic, it is possible to obtain one with a lower melting point than that of a simple substance.

径が大きくなると素材の飛散率が低（なり、密着強度、
作業性が向上する反面、溶射面が粗く気孔も大きくなる
ので、それらを考慮して使用目的に合わせて選択すれば
良い。Powders and granules can be arbitrarily selected and used within the range of 10 to 100μ, but if the diameter is small, the rate of scattering of the material during thermal spraying will be high, but the sprayed surface will be smooth and the pores will be small, and on the other hand,
The larger the diameter, the lower the material scattering rate (becomes), the adhesion strength,
Although workability is improved, the sprayed surface is rougher and the pores are larger, so these should be taken into consideration when selecting a material according to the purpose of use.
