Description
本発明は、気孔を分散した多孔質金属材の取付構造及び取付方法に関し、特に高い気孔率で泡状の気孔を分散した多孔質金属材を被固定部材上に取り付けるための取付構造及び取付方法に関する。 TECHNICAL FIELD The present invention relates to a mounting structure and mounting method for a porous metal material in which pores are dispersed, and in particular, a mounting structure and mounting method for mounting a porous metal material in which foam-like pores are dispersed with a high porosity on a fixed member. About.
ハニカム構造に組み立てられたハニカムセルを有するハニカム金属材や、発泡チタン及び発泡アルミニウムに代表される気孔を分散した発泡バルク金属材など、多くの多孔質金属材が知られている。更に、近年、メッキ法などを利用してスポンジの多孔質形状を転写した多孔質金属材なども開発されている（例えば、特許文献１参照）。 Many porous metal materials are known, such as a honeycomb metal material having honeycomb cells assembled in a honeycomb structure, and a foamed bulk metal material in which pores represented by foamed titanium and foamed aluminum are dispersed. Furthermore, in recent years, a porous metal material in which the porous shape of a sponge is transferred using a plating method or the like has been developed (see, for example, Patent Document 1).
このような多孔質金属材の利用においては、セル（気孔）を画定する金属部分の性質を主に利用する場合と、セル自身の性質を主に利用する場合とがある。金属部分の性質の利用については、金属部分の強度や靭性などの機械的性質、伝熱性などの熱的性質、電気伝導度や誘電特性などの電気的・磁気的性質の利用などがある。また、セル部分の利用については、セルの衝撃吸収、断熱、比重、物質透過などの性質の利用が代表的である。これらの特徴が活かされるように、多孔質金属材を被固定部材上に取り付けて使用されることが多い。 In the use of such a porous metal material, there are a case where the property of the metal part defining the cell (pore) is mainly used and a case where the property of the cell itself is mainly used. The use of the properties of the metal part includes the use of mechanical properties such as strength and toughness of the metal part, thermal properties such as heat transfer, and electrical and magnetic properties such as electrical conductivity and dielectric properties. As for the use of the cell portion, use of properties such as shock absorption, heat insulation, specific gravity, and material permeation of the cell is typical. In order to take advantage of these features, a porous metal material is often used on a member to be fixed.
例えば、特許文献２では、拡散接合法により多孔質金属材を金属からなる被固定部材上に取り付ける方法が開示されている。詳細には、被固定部材である金属板上に金属粉を含む接着剤を塗布して、金属板上に沿って多孔質金属材を配置し、仮固定する。これらを加熱すると、接着剤の中の金属粉が多孔質金属材及び金属板の相互に拡散してこれらを拡散接合できるのである。かかる方法では、接合界面が金属組織的に連続になるため、強固な固定を得ることができる。 For example, Patent Document 2 discloses a method of attaching a porous metal material onto a fixed member made of metal by a diffusion bonding method. Specifically, an adhesive containing metal powder is applied onto a metal plate that is a member to be fixed, and a porous metal material is disposed along the metal plate and temporarily fixed. When these are heated, the metal powder in the adhesive diffuses between the porous metal material and the metal plate and can be diffusion bonded. In such a method, since the joining interface is continuous in terms of metal structure, it is possible to obtain strong fixation.
また、特許文献３では、ハニカムサンドイッチ構造体におけるハニカム金属材と被固定部材とを接着するホットメルト接着剤及びその接着方法が開示されている。ここで、ハニカム金属材の接着は、被固定部材とそれに垂直な方向への線接着によってなされるとし、接着剤としての性能はハニカム金属素材との馴染み、あるいは濡れの善し悪しによって決定されると述べている。すなわち、剪断接着強度と剥離強度とに優れる接着剤が好ましいと述べている。
ところで、泡状の気孔を分散した多孔質金属材のうち、その気孔部分の体積率を６０％以上に高めた多孔質金属材が開発されている。特に、上記した特許文献１に開示の多孔質金属材では、泡状の気孔の気孔率を９０％以上に高めることが出来る。このような高気孔率の多孔質金属材は、内部に含まれる多くの泡状気孔のため、圧縮変形に弱い。故に、多孔質金属材を被固定部材にボルトやねじで固定しようとしても座屈してしまって強固に固定することは出来ない。 Incidentally, among porous metal materials in which foam-like pores are dispersed, a porous metal material in which the volume ratio of the pore portions is increased to 60% or more has been developed. In particular, in the porous metal material disclosed in Patent Document 1 described above, the porosity of the foam-like pores can be increased to 90% or more. Such a porous metal material having a high porosity is vulnerable to compressive deformation due to the many foamed pores contained therein. Therefore, even if it tries to fix a porous metal material to a to-be-fixed member with a volt | bolt or a screw, it buckles and cannot be fixed firmly.
また、上記したような泡状の気孔を分散した多孔質金属材では、その表面に占める金属部分の相対面積が非常に小さく、被固定部材上に配置したときの接触面積が小さいのである。 Moreover, in the porous metal material in which the foam-like pores are dispersed as described above, the relative area of the metal portion occupying the surface is very small, and the contact area when arranged on the fixed member is small.
かかる場合、特許文献２に開示の拡散接合法では、多孔質金属材と被固定部材との接触面積が小さいから、互いの接合強度が低くなってしまうのである。更に、被固定部材が金属を拡散しないＦＲＰやプラスチックなどである場合には、特許文献２に開示の方法は用いることはできない。 In such a case, in the diffusion bonding method disclosed in Patent Document 2, since the contact area between the porous metal material and the fixed member is small, the bonding strength between the two becomes low. Furthermore, when the member to be fixed is FRP or plastic that does not diffuse metal, the method disclosed in Patent Document 2 cannot be used.
更に、特許文献３に開示の方法でも同様であって、多孔質金属材と被固定部材との接触面積が小さいため接合強度は低いのである。また、多孔質金属材の金属素材の種類によっては、接着剤との馴染み、濡れが良好に得られず、接合強度が低いのである。 Furthermore, the method disclosed in Patent Document 3 is the same, and the bonding strength is low because the contact area between the porous metal material and the fixed member is small. In addition, depending on the type of the metal material of the porous metal material, it is difficult to obtain a good fit and wet with the adhesive, and the bonding strength is low.
本発明は、上記したような状況に鑑みてなされたものである。すなわち、高い気孔率で泡状の気孔を分散した多孔質金属材を被固定部材に取り付けるための取付構造及び取付方法であって、被固定部材及び多孔質金属材の材質にかかわらず、しかも互いを強固に固定することができる取付構造及び取付方法を提供しようとするものである。 The present invention has been made in view of the above situation. That is, an attachment structure and an attachment method for attaching a porous metal material in which foam-like pores are dispersed with a high porosity to a fixed member, regardless of the material of the fixed member and the porous metal material. It is an object of the present invention to provide a mounting structure and a mounting method capable of firmly fixing the frame.
本発明は、泡状の気孔を分散した多孔質金属材を被固定部材上に取り付けるための取付構造であって、前記多孔質金属材の一面に露出する前記泡状気孔内に侵入するようにして前記一面に沿って固定層が設けられ、前記固定層が前記被固定部材に固定されていることを特徴とする。 The present invention provides an attachment structure for attaching a porous metal material in which foam-like pores are dispersed on a member to be fixed so as to enter the foam-like pores exposed on one surface of the porous metal material. A fixing layer is provided along the one surface, and the fixing layer is fixed to the member to be fixed.
かかる取付構造によれば、被固定部材に固定された固定層が多孔質金属材の気孔内に侵入し、多孔質金属材の一部を埋包するのである。すなわち、固定層は、多孔質金属材の材質にかかわらず、これを機械的に強固に固定するのである。故に、被固定部材と多孔質金属材とを強固に固定できるのである。 According to this mounting structure, the fixed layer fixed to the member to be fixed penetrates into the pores of the porous metal material and embeds a part of the porous metal material. That is, the fixing layer mechanically fixes the porous metal material regardless of the material of the porous metal material. Therefore, the member to be fixed and the porous metal material can be firmly fixed.
更に、本発明は、泡状気孔を分散した多孔質金属材を被固定部材上に取り付けるための取付方法であって、前記多孔質金属材の一面に露出する前記泡状気孔内に侵入するようにして前記一面に沿って皮膜形成材を塗布する工程と、前記皮膜形成材を硬化せしめて固定層を形成する工程と、前記固定層を前記被固定部材に固定する取付工程と、からなることを特徴とする。 Furthermore, the present invention is an attachment method for attaching a porous metal material in which foam pores are dispersed on a fixed member, so as to enter the foam pores exposed on one surface of the porous metal material. And applying a film forming material along the one surface, curing the film forming material to form a fixing layer, and attaching the fixing layer to the member to be fixed. It is characterized by.
かかる取付方法によれば、固定層が多孔質金属材の気孔内に侵入し、多孔質金属材の一部を埋包するのである。すなわち、固定層は、多孔質金属材の材質にかかわらず、これを機械的に固定するのである。一方、固定層は、圧縮変形等に優れているから被固定部材に容易に固定できる。故に、被固定部材と多孔質金属材とを強固に固定できるのである。 According to this attachment method, the fixed layer penetrates into the pores of the porous metal material and embeds a part of the porous metal material. That is, the fixing layer mechanically fixes the porous metal material regardless of the material of the porous metal material. On the other hand, since the fixing layer is excellent in compression deformation and the like, it can be easily fixed to the fixed member. Therefore, the member to be fixed and the porous metal material can be firmly fixed.
本発明の実施例では、泡状気孔を分散した多孔質金属材であって、６０％以上、特に９０％以上の高い気孔率を有する多孔質金属材であっても、被固定部材上に強固に取り付けることができるのである。このような多孔質金属材は、セル（気孔）の連通の状態によってクローズドセル構造若しくはオープンセル構造に分類されるが、いずれのセル構造であってもよい。また、オープンセル構造であって、特に気孔率を高めた三次元網目骨格からなる三次元網目構造を有する多孔質金属材であってもよい。 In an embodiment of the present invention, even a porous metal material in which foam-like pores are dispersed and has a high porosity of 60% or more, particularly 90% or more, is firmly formed on the fixed member. It can be attached to. Such a porous metal material is classified into a closed cell structure or an open cell structure depending on the state of communication of cells (pores), and any cell structure may be used. Further, it may be a porous metal material having an open cell structure and a three-dimensional network structure composed of a three-dimensional network skeleton having a particularly high porosity.
また、多孔質金属材は、その構造だけでなく、どのような金属であってもよい。すなわち、例えば、鉄、アルミニウム、マグネシウム、ニッケル、又はこれらの金属等からなる合金、例えば、ステンレスなどであってもよい。更に、被固定部材は、アルミニウムやステンレスパネルのような金属、ＦＲＰなどの樹脂など、どのような材質であってもよい。上記したように、本発明では、多孔質金属材の構造及び材質、被固定部材の材質の融通に富むのである。 Further, the porous metal material may be any metal as well as its structure. That is, for example, iron, aluminum, magnesium, nickel, or an alloy made of these metals, for example, stainless steel may be used. Furthermore, the member to be fixed may be any material such as a metal such as aluminum or a stainless steel panel, or a resin such as FRP. As described above, in the present invention, the structure and material of the porous metal material and the material of the member to be fixed are versatile.
本発明の実施例としての取付方法では、多孔質金属材の一面である固定面には、熱可塑性樹脂、熱硬化性樹脂、光硬化性樹脂などの樹脂、若しくは、各種ＦＲＲ、ろう等からなる皮膜形成材が積層塗布されて、一定の厚さの皮膜を形成する。このとき皮膜形成材は多孔質金属材の固定面に露出した泡状気孔内に侵入するように塗布される。なお、この操作は脱気環境下で行うと泡状気孔内に皮膜形成材が侵入しやすく好ましい。ここで、皮膜形成材が熱硬化性樹脂である場合には冷却又は放置し、化学硬化性樹脂である場合には加温又は放置する。また光硬化性樹脂である場合には紫外線などを照射して、皮膜形成材を硬化せしめて固定層を形成する。すなわち、多孔質金属材の固定面に沿って固定層が設けられるのである。固定層は、多孔質金属材の泡状気孔内に嵌合しているため、機械的に多孔質金属材と強固に固定される。この固定層は被固定部材の取付面にボルト、ねじ、接着剤など、公知の方法で固定される。 In the mounting method as an embodiment of the present invention, the fixed surface, which is one surface of the porous metal material, is made of a resin such as a thermoplastic resin, a thermosetting resin, a photocurable resin, or various FRRs, waxes, and the like. A film forming material is laminated and applied to form a film having a certain thickness. At this time, the film forming material is applied so as to penetrate into the bubble-like pores exposed on the fixed surface of the porous metal material. In addition, it is preferable that this operation is performed in a degassed environment because the film-forming material can easily enter into the foam pores. Here, when the film forming material is a thermosetting resin, it is cooled or left standing, and when it is a chemical curable resin, it is heated or left standing. In the case of a photo-curable resin, ultraviolet light or the like is irradiated to cure the film forming material to form a fixed layer. That is, the fixing layer is provided along the fixing surface of the porous metal material. Since the fixing layer is fitted in the foamed pores of the porous metal material, the fixing layer is mechanically firmly fixed to the porous metal material. This fixing layer is fixed to the mounting surface of the fixed member by a known method such as a bolt, a screw, or an adhesive.
かかる方法により得られる多孔質金属材の取付構造では、固定層が多孔質金属材の気孔内に侵入し、多孔質金属材の一部を埋包するのである。すなわち、固定層は、多孔質金属材の材質にかかわらず、これを機械的に固定するのである。一方、固定層は、圧縮変形等の抗力に優れているから被固定部材に容易に固定できる。故に、被固定部材と多孔質金属材とを強固に固定できるのである。 In the attachment structure of the porous metal material obtained by such a method, the fixed layer penetrates into the pores of the porous metal material and embeds a part of the porous metal material. That is, the fixing layer mechanically fixes the porous metal material regardless of the material of the porous metal material. On the other hand, since the fixing layer is excellent in resistance to compression deformation and the like, it can be easily fixed to the member to be fixed. Therefore, the member to be fixed and the porous metal material can be firmly fixed.
また皮膜形成材がエポキシや各種接着剤であって被固定部材と化学的に接着可能である場合には、多孔質金属材を直接、被固定部材に固定できるのである。かかる場合においても、該接着剤は多孔質金属材と化学的に接着可能である必要はない。すなわち、多孔質金属材は該接着剤によって形成される固定層と機械的に強固に固定されるからである。 When the film forming material is epoxy or various adhesives and can be chemically bonded to the member to be fixed, the porous metal material can be directly fixed to the member to be fixed. Even in such a case, the adhesive does not need to be able to be chemically bonded to the porous metal material. That is, the porous metal material is mechanically firmly fixed to the fixing layer formed by the adhesive.
［比較例］
比較例として、図１に示すように、ハニカム金属材１０１は、互いに平行に並ぶ断面多角形のストレートセル１０２を複数有している。ストレートセル１０２の長手方向Ａが被固定部材１０３の取付面１０３ａと垂直になるように、すなわち、長手方向Ａが取付面１０３ａの法線方向と平行となるように、ハニカム金属材１０１を取付面１０３ａ上に配置するのである。このとき、被固定部材１０３の取付面１０３ａには接着剤１０４が薄く与えられている。
[Comparative example]
As a comparative example, as shown in FIG. 1, the honeycomb metal material 101 includes a plurality of straight cells 102 having a polygonal cross section arranged in parallel to each other. The honeycomb metal material 101 is mounted on the mounting surface so that the longitudinal direction A of the straight cell 102 is perpendicular to the mounting surface 103a of the fixed member 103, that is, the longitudinal direction A is parallel to the normal direction of the mounting surface 103a. It is arranged on 103a. At this time, the adhesive 104 is thinly applied to the mounting surface 103 a of the fixed member 103.
図２に示すように、接着剤１０４は、ハニカム金属材１０１の長手方向Ａに垂直な断面ｓと被固定部材１０３の取付面１０３ａとの間を化学的に接合する。この断面ｓの面積が小さいと、接着面積が小さくなってしまって、ハニカム金属材１０１と被固定部材１０３との接着強度は十分に得られない。すなわち、被固定部材１０３の取付面１０３ａと垂直な方向（すなわち、Ａ方向）への力Ｆによって、ハニカム金属材１０１が被固定部材１０３から脱離してしまうのである。また、ハニカム金属材１０１の金属素材の種類によっては、接着剤１０４とハニカム金属材１０１との馴染み、濡れが得られず、やはり接着強度は得られないのである。 As shown in FIG. 2, the adhesive 104 chemically bonds the section s perpendicular to the longitudinal direction A of the honeycomb metal material 101 and the mounting surface 103 a of the fixed member 103. When the area of the cross section s is small, the bonding area is small, and the bonding strength between the honeycomb metal material 101 and the fixed member 103 cannot be sufficiently obtained. That is, the honeycomb metal material 101 is detached from the fixed member 103 by the force F in the direction perpendicular to the mounting surface 103 a of the fixed member 103 (that is, the A direction). In addition, depending on the type of the metal material of the honeycomb metal material 101, the adhesive 104 and the honeycomb metal material 101 are not familiar and do not get wet, and the adhesive strength cannot be obtained.
そこで、図３に示すように、エポキシのような肉盛り可能な接着剤１０４’によって、ハニカム金属材１０１の金属部分の一部を埋入せしめるのである。これにより、ハニカム金属材１０１の長手方向Ａと平行な面ｓ’の一部についても接着面積に加えることができる。ここで、被固定部材１０３の取付面１０３ａと垂直な方向（すなわち、Ａ方向）への力Ｆによって、ハニカム金属材１０１の面ｓ’では剪断力が生じる。つまり、面ｓ’においても接着剤１０４’が十分な化学的接合力を有していなければかかる剪断力に降伏してしまうのである。つまり、接着剤１０４’に対するハニカム金属材１０１の金属素材の種類によっては、やはり接着強度は得られないのである。 Therefore, as shown in FIG. 3, a part of the metal portion of the honeycomb metal material 101 is embedded by an adhesive 104 ′ that can be built up such as epoxy. Thereby, a part of the surface s ′ parallel to the longitudinal direction A of the honeycomb metal material 101 can be added to the bonding area. Here, a shearing force is generated on the surface s ′ of the honeycomb metal material 101 by the force F in the direction perpendicular to the mounting surface 103a of the fixed member 103 (that is, the A direction). That is, if the adhesive 104 'does not have a sufficient chemical bonding force even on the surface s', it yields to such a shearing force. That is, depending on the type of the metal material of the honeycomb metal material 101 with respect to the adhesive 104 ′, the adhesive strength cannot be obtained.
以上、比較例によれば、ハニカム金属材１０１と被固定部材１０３との固定強度は接着剤１０４’に対するそれぞれの素材に依存するとともに、強固に固定することはできないのである。 As described above, according to the comparative example, the fixing strength between the honeycomb metal material 101 and the fixed member 103 depends on the respective materials for the adhesive 104 ′ and cannot be firmly fixed.
本発明の実施例について、図４乃至１１を用いて詳細に説明する。 An embodiment of the present invention will be described in detail with reference to FIGS.
図４に示すように、泡状気孔を分散した多孔質金属材１０の平面若しくは曲面からなる固定面１０ａに熱硬化性樹脂、例えば、ＦＲＰからなる皮膜形成材１５を数回に分けて、一定の厚さの皮膜を形成するまで重ねて塗布する（図４（ａ）及び（ｂ）を参照）。このとき皮膜形成材１５は多孔質金属材１０の固定面１０ａに露出している気孔１１内に侵入するように塗布される。なお、この操作を脱気環境下で行うと、気孔１１内に皮膜形成材１５を侵入させやすく、また皮膜形成材１５に気泡を巻き込まず、好ましい。 As shown in FIG. 4, a thermosetting resin, for example, a film forming material 15 made of FRP, is divided into several times on a fixed surface 10a made of a flat surface or a curved surface of the porous metal material 10 in which foam pores are dispersed. The film is applied repeatedly until a film having a thickness of 10 mm is formed (see FIGS. 4A and 4B). At this time, the film forming material 15 is applied so as to enter the pores 11 exposed on the fixed surface 10 a of the porous metal material 10. Note that it is preferable to perform this operation in a deaerated environment because the film forming material 15 can easily enter the pores 11 and air bubbles are not involved in the film forming material 15.
次に、多孔質金属材１０とともに皮膜形成材１５をこのまま放置するなどして、皮膜形成材１５を固化させると、固定層１６が形成される（図４（ｃ）を参照）。このとき固定層１６に多孔質金属材１０の一部が埋包されている。 Next, when the film forming material 15 is solidified by leaving the film forming material 15 together with the porous metal material 10 as it is, a fixed layer 16 is formed (see FIG. 4C). At this time, a part of the porous metal material 10 is embedded in the fixed layer 16.
多孔質金属材１０と固定層１６とが一体となった複合体は、適宜、被固定部材２０に固定される（図４（ｄ）を参照）。このとき固定層１６はＦＲＰパネルなどと同様に、被固定部材２０にねじ１７によって固定が可能である。また、接着、ボルトなど公知の固定方法を用いることも可能である。 The composite body in which the porous metal material 10 and the fixed layer 16 are integrated is appropriately fixed to the fixed member 20 (see FIG. 4D). At this time, the fixing layer 16 can be fixed to the fixed member 20 with the screw 17 as in the FRP panel or the like. It is also possible to use known fixing methods such as adhesion and bolts.
ここで、１つの実施例として、図５及び図６に示すように、多孔質金属材１０のうち、泡状気孔を分散したクローズドセル構造を有する多孔質金属材１０−１では、その固定面１０ａに多くの気孔１１が開口している。また気孔１１を確定する金属部分１２は、固定面１０ａにおいて連続している（特に図５参照）。 Here, as one example, as shown in FIGS. 5 and 6, among the porous metal material 10, the porous metal material 10-1 having a closed cell structure in which bubble-like pores are dispersed is fixed to the fixed surface. Many pores 11 are open at 10a. Further, the metal portion 12 defining the pores 11 is continuous on the fixed surface 10a (see particularly FIG. 5).
図７に示すように、多孔質金属材１０−１の固定面１０ａと垂直な断面において、固定面１０ａにおいて開口している気孔１１のうちのいくつかは、気孔１１の内部から固定面１０ａに向けて断面積を徐々に拡大した形状を有する。つまり、固定層１６には、かかる気孔１１の形状を転写した凸部１６−１ａが形成されるのである。このような凸部１６−１ａは気孔１１内に形成されるが、多孔質金属材１０−１を固定層１６から離間させる方向に働く力Ｆによって、凸部１６−１ａは容易に気孔１１内から抜けてしまうのである。 As shown in FIG. 7, in the cross section perpendicular to the fixed surface 10 a of the porous metal material 10-1, some of the pores 11 opened in the fixed surface 10 a are formed from the inside of the pore 11 to the fixed surface 10 a. It has a shape with a gradually increasing cross-sectional area. In other words, the fixed layer 16 is formed with convex portions 16-1a to which the shape of the pores 11 is transferred. Such convex portions 16-1a are formed in the pores 11. However, the convex portions 16-1a are easily formed in the pores 11 by the force F acting in the direction of separating the porous metal material 10-1 from the fixed layer 16. It will escape from.
一方、図８に示すように、多孔質金属材１０−１の固定面１０ａにおいて開口している気孔１１のうちのいくつかは、気孔１１の内部から固定面１０ａに向けて断面積を徐々に減少させた形状を有する。すなわち、このような気孔１１の形状を転写した固定層１６の凸部１６−１ｂは、力Ｆによって気孔１１内からは脱離しない。故に、多孔質金属材１０−１と固定層１６とは、強固に固定されるのである。 On the other hand, as shown in FIG. 8, some of the pores 11 opened in the fixed surface 10 a of the porous metal material 10-1 gradually increase in cross-sectional area from the inside of the pore 11 toward the fixed surface 10 a. Has a reduced shape. That is, the convex portions 16-1b of the fixed layer 16 to which the shape of the pores 11 is transferred are not detached from the pores 11 by the force F. Therefore, the porous metal material 10-1 and the fixed layer 16 are firmly fixed.
更に、他の実施例として、図９及び図１０に示すように、三次元網目骨格からなる三次元網目構造により泡状気孔を分散したオープンセル型の多孔質金属材１０−２では、その固定面１０ａに多くの気孔１１が開口している。ここで気孔１１を確定する金属部分１２は、固定面１０ａにおいて不連続であって、島状に分布している（特に図１０参照）。 Furthermore, as another embodiment, as shown in FIG. 9 and FIG. 10, in the open cell type porous metal material 10-2 in which the foam pores are dispersed by the three-dimensional network structure composed of the three-dimensional network skeleton, the fixing is performed. Many pores 11 are opened on the surface 10a. Here, the metal portions 12 that define the pores 11 are discontinuous on the fixed surface 10a and are distributed in an island shape (see particularly FIG. 10).
図９及び図１１に示すように、多孔質金属材１０−２では、金属部分１２は樹枝状に分岐しており、その樹枝径は場所によって異なるのである。また固定層１６内において屈曲している。故に、多孔質金属材１０−２を固定層１６から離間させる方向に働く力Ｆによって、多孔質金属材１０−２が固定層１６から脱離しないのである。つまり、固定層１６が被固定部材２０に強固に固定されると、多孔質金属材１０−２と固定層１６とも強固に固定されるのである。 As shown in FIGS. 9 and 11, in the porous metal material 10-2, the metal portion 12 is branched in a dendritic shape, and the diameter of the tree branches varies depending on the location. Further, it is bent in the fixed layer 16. Therefore, the porous metal material 10-2 is not detached from the fixed layer 16 due to the force F acting in the direction of separating the porous metal material 10-2 from the fixed layer 16. That is, when the fixing layer 16 is firmly fixed to the fixed member 20, the porous metal material 10-2 and the fixing layer 16 are also firmly fixed.
以上、本実施例によれば、固定層が多孔質金属材の気孔内に侵入し、多孔質金属材の一部を埋包するのである。すなわち、固定層は、多孔質金属材の材質にかかわらず、これを機械的に固定するのである。一方、固定層は、圧縮変形等に優れているから被固定部材に容易に固定できる。故に、被固定部材と多孔質金属材とを強固に固定できるのである。 As described above, according to the present embodiment, the fixed layer penetrates into the pores of the porous metal material and embeds a part of the porous metal material. That is, the fixing layer mechanically fixes the porous metal material regardless of the material of the porous metal material. On the other hand, since the fixing layer is excellent in compression deformation and the like, it can be easily fixed to the fixed member. Therefore, the member to be fixed and the porous metal material can be firmly fixed.
なお、一定の厚さに形成された皮膜形成材１５に多孔質金属材１０の固定面１０ａを浸漬して、多孔質金属材１０及び固定層１６を一体に形成しても良い。かかる場合、被固定部材２０に係止された係止鋲を埋包するように皮膜形成材１５を形成することで、被固定部材２０の上に固定層１６を介して多孔質金属材１０を固定することも可能である。また、被固定部材２０を設けず、多孔質金属材１０の取り付けを所望する部分に直接、固定層１６を設けても良い。すなわち、固定層１６が被固定部材２０を兼ねていても良い。 Alternatively, the porous metal material 10 and the fixing layer 16 may be integrally formed by immersing the fixing surface 10a of the porous metal material 10 in the film forming material 15 formed to have a certain thickness. In such a case, the porous metal material 10 is formed on the fixed member 20 via the fixing layer 16 by forming the film forming material 15 so as to embed the locking rod locked to the fixed member 20. It is also possible to fix. Further, the fixing layer 16 may be provided directly on the portion where the porous metal material 10 is desired to be attached without providing the member 20 to be fixed. That is, the fixed layer 16 may also serve as the fixed member 20.
以上によれば、多孔質金属材１０の取り付けのための作業工程が大幅に簡略化できるのである。 According to the above, the work process for attaching the porous metal material 10 can be greatly simplified.
