［産業上の利用分野］
本発明は、自溶合金溶射皮膜を介して金属を接

なく、母材金属より低融点のろう材を接合材とし
て用いるろう接法、及び金属の高温での相互拡散
現象を利用した拡散接合法がある。[Conventional technology] Conventional metallurgical joining methods include fusion welding, typically arc welding, in which a part of the base metal to be joined and welding material are melted and joined, and soldering. There is a brazing method that uses a brazing material with a lower melting point than the base metal as a bonding material without melting the base metal, and a diffusion bonding method that utilizes the interdiffusion phenomenon of metals at high temperatures.
融接の場合は、母材の形状、接合面の大きさ及
び母材の材質が制約され、特に溶接性の劣る鋳
鉄、合金鋼などの場合には適用しにくい。 In the case of fusion welding, there are restrictions on the shape of the base metal, the size of the joint surface, and the material of the base metal, and it is difficult to apply it particularly to cast iron, alloy steel, etc., which have poor weldability.
ろう接の場合には、接合強度が劣り、強度部材
の接合法としては適当でない。 In the case of brazing, the joining strength is poor and it is not suitable as a joining method for strength members.
また、拡散接合は真空中あるいは雰囲気中での
加熱、加圧が必要であり、設備費が高く、しかも
簡便性に難点がある。 Furthermore, diffusion bonding requires heating and pressurization in a vacuum or atmosphere, resulting in high equipment costs and disadvantages in simplicity.
［発明が解決しようとする問題点］
本接合法は、母材の形状に制約されずに、多面
でしかも広範囲面の接合が一度にできる利点があ
る。また、通常、大気中で母材の自重のみで接合
できるため、極めて簡便で適用性の広い方法であ
る。[Problems to be Solved by the Invention] This joining method has the advantage of being able to join multiple surfaces and a wide range of surfaces at once without being restricted by the shape of the base material. Furthermore, since bonding can usually be performed in the atmosphere using only the weight of the base materials, it is an extremely simple and widely applicable method.
本法により、JIS MSFNi4（ニツケル・クロム
自溶合金）を用いて、軟鋼（SS41）及び球状黒
鉛鋳鉄を接合した場合、引張強度は245〜
265MPA、せん断強度は58MPA（平均）である。 By this method, when mild steel (SS41) and spheroidal graphite cast iron are joined using JIS MSFNi4 (nickel-chromium self-fluxing alloy), the tensile strength is 245~
265MPA, shear strength is 58MPA (average).
［実施例］ 次に、その接合方法を説明する。[Example] Next, the joining method will be explained.
(イ) 双方の金属の接合面１に自溶合金を溶射し、
溶射皮膜を形成させる。(a) Spraying a self-fluxing alloy on the joint surface 1 of both metals,
Forms a thermal spray coating.
(ロ) その後、双方の接合面に合わせて、大気中に
て、接合部２を溶射皮膜の再溶融温度に加熱す
る。この場合、加熱源はガス炎、高周波、加熱
炉等を用い、再溶融温度に達した後は特に保持
する必要はない。(b) Thereafter, the joint portion 2 is heated in the atmosphere to the remelting temperature of the thermal spray coating, in accordance with both joint surfaces. In this case, the heating source is a gas flame, high frequency, heating furnace, etc., and there is no need to hold it after the remelting temperature is reached.
(ハ) 加熱後は空気中に放置するか、あるいは徐冷
する。(c) After heating, leave it in the air or slowly cool it.
(ニ) 割れの生じた部品、巣のある鋳造品を補修す
る場合は、これら欠陥部３を４のように切り取
る。(d) When repairing cracked parts or cast parts with cavities, cut out these defective parts 3 as shown in 4.
(ホ) 切り取り部４の形状で、溶射皮膜厚さ代分縮
小した補修片５を作成し、接合面双方に溶射を
行う。(e) A repair piece 5 is created in the shape of the cutout 4 and reduced by the thickness of the thermal spray coating, and thermal spray is applied to both joint surfaces.
(ヘ) 補正部にはめ込み６、以下(ロ)、(ハ)と同一の処
理を施す。(F) Inset the correction section 6 and perform the same processing as in (B) and (C) below.
以上のような簡単な手順により、接合部２にお

Since it is easy to adjust the thickness of the sprayed coating, this joining method can be used to join parts with complex shapes, making it an extremely versatile joining method.
