Description

本発明は、セラミックスを含むペレットを金属中に鋳込むことで設けられた複合材及びその製造方法に関する。   The present invention relates to a composite material provided by casting a pellet containing ceramics into a metal and a method for manufacturing the composite material.

鉄基合金は、金属組織の形態、含有成分の種類及びその割合に応じて諸特性が様々に変化する。例えば、C量が少ない鋼材は高強度、高剛性を示し、C量が多い鋳鉄材は、強度や剛性は鋼材に若干劣るものの、鋼材に比して鋳造が容易である。換言すれば、鋳造性に優れる。   Iron-based alloys have various properties that vary depending on the form of the metal structure, the type of contained components, and their proportions. For example, a steel material with a small amount of C shows high strength and high rigidity, and a cast iron material with a large amount of C is slightly inferior in strength and rigidity to steel materials, but is easier to cast than steel materials. In other words, the castability is excellent.

ところで、構造材を設ける場合、該構造材に高剛性が希求されることがある。この際、例えば、鋳鉄材を用いて鋳造を行うと、得られた構造材の剛性が十分でないことが懸念される。   By the way, when providing a structural material, high rigidity may be calculated | required by this structural material. At this time, for example, when casting is performed using a cast iron material, there is a concern that the rigidity of the obtained structural material is not sufficient.

このような観点から、金属材にセラミックスを分散させ、金属材の特性を活用しつつ、セラミックスによって希求される特性の確保を図った金属基複合材が提案されている。この種の金属基複合材を製造する方法としては、コンポキャスト法が例示される。すなわち、金属溶湯にセラミックス粉末を添加して鋳造を行う手法である。   From such a point of view, a metal matrix composite material has been proposed in which ceramics are dispersed in a metal material and the properties required of the ceramic material are secured while utilizing the properties of the metal material. As a method for producing this type of metal matrix composite material, a composite casting method is exemplified. In other words, this is a technique in which ceramic powder is added to a molten metal for casting.

しかしながら、コンポキャスト法を実施する場合、セラミックス粉末が金属溶湯と分離し易く、このためにセラミックスを分散させることが容易ではないという不都合がある。セラミックス粉末が分離したまま鋳造を行うと、溶湯を凝固させて鋳造品とした際、該鋳造品ではセラミックス相と金属相とが分離してしまう。   However, when the compocast method is performed, there is a disadvantage that the ceramic powder is easily separated from the molten metal, and thus it is not easy to disperse the ceramic. When casting is performed with the ceramic powder separated, when the molten metal is solidified to form a cast product, the ceramic phase and the metal phase are separated in the cast product.

このような相分離を回避するためには、特許文献1に記載されるように、鉄基合金の溶湯にSiC粒子を添加した後、この溶湯ないし固化物を鋳鉄材の溶湯に添加して凝固することで複合材とすることや、特許文献2に記載されるように、金属ホウ化物固溶体粒子を分散した炭化ケイ素セラミックス焼結体、又は金属ホウ化物固溶体セラミックス焼結体の少なくともいずれか一方を、マルテン系高クロム鋳鉄、高Ni合金系グレン鋳鉄、マルテン系ハイス鋼等で鋳ぐるんで鋳ぐるみ複合体とすることが想起される。   In order to avoid such phase separation, as described in Patent Document 1, after adding SiC particles to the molten iron-based alloy, this molten or solidified material is added to the molten cast iron material to solidify. As described in Patent Document 2, at least one of silicon carbide ceramics sintered body in which metal boride solid solution particles are dispersed or metal boride solid solution ceramics sintered body is used. It is conceived that a cast-in-line composite is made by casting with marten-based high chromium cast iron, high Ni alloy-based grain cast iron, martens-based high-speed steel, or the like.

特公平7−11045号公報Japanese Patent Publication No.7-11045 特開2004−307893号公報JP 2004-307893 A

鉄基合金の溶湯の比重は、概ね6.8〜8.0の範囲内である。一方、例えば、鋼材を母材としてTiCを50体積%含有させたペレット、VCを60体積%含有させたペレットの比重は、それぞれ、6.4、6.6であり、鉄基合金に比して小さい。従って、このようなペレットを溶湯に添加すると、ペレットが溶湯の界面に浮上したり、ペレットの形状によっては溶湯中で長手方向が鉛直方向に沿って延在したりすることがある。このような事態が生じると、該溶湯が凝固した鋳造品(複合材)では前記ペレットが偏在しているので、全体にわたって諸特性を向上させることが困難となる。   The specific gravity of the molten iron-based alloy is generally in the range of 6.8 to 8.0. On the other hand, for example, the specific gravity of a pellet containing 50% by volume of TiC using a steel material as a base material and a pellet containing 60% by volume of VC is 6.4 and 6.6, respectively. Small. Therefore, when such a pellet is added to the molten metal, the pellet may float on the interface of the molten metal, or the longitudinal direction may extend along the vertical direction in the molten metal depending on the shape of the pellet. When such a situation occurs, the pellets are unevenly distributed in the cast product (composite material) in which the molten metal is solidified, so that it is difficult to improve various characteristics throughout.

本発明は上記した問題を解決するためになされたもので、セラミックスを含むペレットを鋳込むことが容易な複合材及びその製造方法を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a composite material in which a pellet containing ceramics can be easily cast and a method for manufacturing the composite material.

前記の目的を達成するために、本発明は、セラミックス相を含むペレットを金属中に鋳込むことで設けられた複合材であって、
前記ペレットは、セラミックス相を20〜70体積%以上含有し、残部がニッケル合金又は銅合金であり、且つ比重が6.7〜7.3であり、
前記金属は、鋳鉄材であることを特徴とする。ここで、本発明においては、ニッケル自体もニッケル合金に含めるとともに、銅自体も銅合金に含めるものとする。また、ペレットは成形体であってもよいし、粉砕物であってもよい。
In order to achieve the above object, the present invention is a composite material provided by casting a pellet containing a ceramic phase into a metal,
The pellet contains 20 to 70% by volume or more of a ceramic phase, the remainder is a nickel alloy or a copper alloy, and the specific gravity is 6.7 to 7.3,
The metal is a cast iron material. Here, in the present invention, nickel itself is included in the nickel alloy, and copper itself is included in the copper alloy. The pellet may be a molded body or a pulverized product.

すなわち、本発明においては、金属相としてニッケル合金又は銅合金を含む。これらは鋳鉄材に比して比重が大きく、従って、ペレットの比重を鋳鉄溶湯の比重に近似させることが容易となる。   That is, in this invention, a nickel alloy or a copper alloy is included as a metal phase. These have a higher specific gravity than cast iron, and therefore it is easy to approximate the specific gravity of pellets to the specific gravity of molten cast iron.

しかも、本発明では、ペレットの比重を6.7〜7.3としているので、該ペレットが鋳鉄溶湯から分離し難い。このため、複合材では、ペレットが略均等に分散するので、全体にわたって諸特性、特にヤング率を向上させることができる。   Moreover, in the present invention, since the specific gravity of the pellet is set to 6.7 to 7.3, the pellet is difficult to separate from the cast iron melt. For this reason, in a composite material, since pellets disperse substantially uniformly, various properties, particularly Young's modulus, can be improved throughout.

例えば、セラミックス相の組成比を変更することで比重を鋳鋼溶湯の比重に近似させるようにしてもよい。すなわち、本発明は、セラミックス相を含むペレットを金属中に鋳込むことで設けられた複合材であって、
前記ペレットは、セラミックス相を20〜70体積%以上含有し、残部がニッケル合金又は銅合金であり、且つ比重が7.6〜8.4であり、
前記金属は、鋳鋼材であることを特徴とする。
For example, the specific gravity may be approximated to the specific gravity of the molten cast steel by changing the composition ratio of the ceramic phase. That is, the present invention is a composite material provided by casting a pellet containing a ceramic phase into a metal,
The pellet contains 20 to 70% by volume or more of a ceramic phase, the remainder is a nickel alloy or a copper alloy, and the specific gravity is 7.6 to 8.4,
The metal is a cast steel material.

このように、本発明によれば、鋳鋼材を母材とする複合材を構成することもできる。   Thus, according to this invention, the composite material which uses a cast steel material as a base material can also be comprised.

また、本発明は、セラミックス相を含むペレットを金属中に鋳込むことで複合材を設ける複合材の製造方法であって、
セラミックス相を20〜70体積%以上含有し、残部がニッケル合金又は銅合金であり、且つ比重が6.7〜7.3である前記ペレットを設ける工程と、
前記ペレットを鋳鉄溶湯に添加した後に鋳造を行う工程と、
前記鋳鉄溶湯を凝固させて前記ペレットが鋳込まれた前記複合材を設ける工程と、
を有することを特徴とする。
Further, the present invention is a method for producing a composite material in which a composite material is provided by casting a pellet containing a ceramic phase into a metal,
A step of providing the pellets containing 20 to 70% by volume of a ceramic phase, the balance being a nickel alloy or a copper alloy, and a specific gravity of 6.7 to 7.3;
Casting after adding the pellets to the cast iron melt;
Providing the composite material in which the cast iron melt is solidified and the pellets are cast;
It is characterized by having.

上記したように、この場合、ペレットの比重が鋳鉄溶湯の比重に近いので、ペレットが略均等に鋳鉄溶湯中に分散する。このため、全体にわたって諸特性に優れる複合材を容易に得ることができる。   As described above, in this case, since the specific gravity of the pellets is close to the specific gravity of the cast iron melt, the pellets are dispersed almost uniformly in the cast iron melt. For this reason, the composite material which is excellent in various characteristics over the whole can be obtained easily.

勿論、鋳鋼材を母材とする複合材を設けるようにしてもよい。すなわち、本発明は、セラミックス相を含むペレットを金属中に鋳込むことで複合材を設ける複合材の製造方法であって、
セラミックス相を20〜70体積%以上含有し、残部がニッケル合金又は銅合金であり、且つ比重が7.6〜8.4である前記ペレットを設ける工程と、
前記ペレットを鋳鋼溶湯に添加した後に鋳造を行う工程と、
前記鋳鋼溶湯を凝固させて前記ペレットが鋳込まれた前記複合材を設ける工程と、
を有することを特徴とする。
Of course, a composite material having a cast steel material as a base material may be provided. That is, the present invention is a method for producing a composite material in which a composite material is provided by casting a pellet containing a ceramic phase into a metal,
A step of providing the pellets containing 20 to 70% by volume of a ceramic phase, the balance being a nickel alloy or a copper alloy, and a specific gravity of 7.6 to 8.4;
Casting after adding the pellets to the molten cast steel;
Providing the composite material in which the pellet is cast by solidifying the cast steel melt;
It is characterized by having.

この場合においては、ペレットの比重が鋳鋼溶湯の比重に近いので、鋳鋼材を母材金属とし、且つ全体にわたって諸特性に優れる複合材を容易に得ることができる。   In this case, since the specific gravity of the pellets is close to the specific gravity of the molten cast steel, it is possible to easily obtain a composite material in which the cast steel material is a base metal and is excellent in various characteristics throughout.

いずれの場合においても、前記セラミックス相の好適な例としては、TiC、VC、SiCの少なくともいずれか1種が挙げられる。   In any case, a preferable example of the ceramic phase includes at least one of TiC, VC, and SiC.

本発明によれば、ニッケル合金又は銅合金を金属相とすることで鋳鉄溶湯ないし鋳鋼溶湯の比重に近い比重を有するペレットを添加して鋳造を行うようにしているので、ペレットが鋳鉄溶湯ないし鋳鋼溶湯から分離することが回避される。このため、全体にわたって諸特性、特にヤング率が向上した複合材を作製することが容易となる。   According to the present invention, since the nickel alloy or the copper alloy is used as the metal phase, the pellet having the specific gravity close to the specific gravity of the cast iron melt or cast steel is added to perform casting. Separation from the melt is avoided. For this reason, it becomes easy to produce a composite material in which various properties, in particular, Young's modulus are improved throughout.

以下、本発明に係る複合材の製造方法につき好適な実施の形態を挙げ、添付の図面を参照して詳細に説明する。   Hereinafter, preferred embodiments of the method for producing a composite material according to the present invention will be described in detail with reference to the accompanying drawings.

先ず、本発明の第1実施形態に係る複合材につきその製造方法との関連で説明する。第1実施形態に係る複合材は、母材金属である鋳鉄中に、セラミックス相を20〜70体積%以上含有し、残部がニッケル合金又は銅合金であり、且つ比重が6.7〜7.3であるペレットが鋳込まれて構成されたものである。   First, the composite material according to the first embodiment of the present invention will be described in relation to its manufacturing method. The composite material which concerns on 1st Embodiment contains 20-70 volume% or more of ceramic phases in the cast iron which is a base metal, the remainder is a nickel alloy or a copper alloy, and specific gravity is 6.7-7. 3 is formed by casting a pellet.

この複合材は、セラミックス含有添加材としてのペレットを設ける第1工程と、前記ペレットを鋳鉄溶湯に添加して鋳造を行う第2工程と、前記鋳鉄溶湯を凝固させて鋳造品(複合材)を設ける第3工程とを有する製造方法によって作製することができる。   The composite material includes a first step of providing pellets as a ceramic-containing additive, a second step of adding the pellets to the cast iron melt and casting, and solidifying the cast iron melt to obtain a cast product (composite material). It can produce with the manufacturing method which has the 3rd process to provide.

第1工程において、ペレットは、例えば、セラミックス粉末と金属粉末とを混合した混合粉末を成形することで設けることができる。ペレットの形状は、例えば、ディスク体形状や円柱体形状とすることができるが、特にこれらの形状に限定されるものではない。   In the first step, the pellet can be provided, for example, by molding a mixed powder obtained by mixing ceramic powder and metal powder. The shape of the pellet can be, for example, a disk shape or a cylindrical shape, but is not particularly limited to these shapes.

又は、セラミックス粉末を金属溶湯に添加したものを凝固させて設けるようにしてもよいし、セラミックス相を金属中に晶出ないし析出させることでセラミックス相が金属中に含まれるようにしてもよい。これらの場合、セラミックス相と金属相とが分離したペレットが作製されても特に差し支えはない。   Alternatively, a ceramic powder added to a molten metal may be solidified, or the ceramic phase may be crystallized or precipitated in the metal so that the ceramic phase is included in the metal. In these cases, there is no particular problem even if a pellet in which the ceramic phase and the metal phase are separated is produced.

さらに、上記のようにして得られた固形物を粉砕するようにしてもよい。   Furthermore, you may make it grind | pulverize the solid substance obtained as mentioned above.

以上のようにして、セラミックス相と金属相とを含むペレットが作製される。   As described above, a pellet containing a ceramic phase and a metal phase is produced.

ここで、ペレット中のセラミックス相は、20〜70体積%に設定される。すなわち、ペレットを作製する際、セラミックス粉末が20〜70体積%を占めるように添加される。20体積%未満であると、ヤング率、ひいては剛性を向上させる効果に乏しい。一方、70体積%を超えると、鋳鉄溶湯との比重差が大きくなるのでペレットが鋳鉄溶湯から分離してしまう。   Here, the ceramic phase in the pellet is set to 20 to 70% by volume. That is, when producing a pellet, it adds so that ceramic powder may occupy 20-70 volume%. If it is less than 20% by volume, the effect of improving the Young's modulus and consequently the rigidity is poor. On the other hand, if it exceeds 70% by volume, the specific gravity difference from the cast iron melt becomes large, so that the pellets are separated from the cast iron melt.

セラミックス粉末としては、TiC、VC、SiCの少なくともいずれか1種が好ましい。これらが金属材中に分散された複合材は、母材である金属材に比して大きなヤング率を示すからである。   The ceramic powder is preferably at least one of TiC, VC, and SiC. This is because a composite material in which these are dispersed in a metal material exhibits a higher Young's modulus than a metal material that is a base material.

なお、ペレットのペレット径は、0.25〜3mmであることが好ましい。ペレットのペレット径が0.25mm未満であると、金属溶湯から分離し易い。また、ペレット径が3mmよりも大きいペレットを用いると、鋳造品に対する引け巣抑制効果が乏しくなる傾向がある。ペレット径は、例えば、粉砕物を所定の篩で選別することで調整することができる。   In addition, it is preferable that the pellet diameter of a pellet is 0.25-3 mm. It is easy to isolate | separate from a molten metal as the pellet diameter of a pellet is less than 0.25 mm. Moreover, when a pellet having a pellet diameter larger than 3 mm is used, there is a tendency that the shrinkage cavity suppressing effect on the cast product is poor. The pellet diameter can be adjusted, for example, by selecting the pulverized product with a predetermined sieve.

一方の金属相は、上記したように、ニッケル合金相又は銅合金相から形成される。ニッケル合金、銅合金は鋳鉄材に比して比重が大きく、このため、ペレットが溶湯から分離し難くなる。   One metal phase is formed of a nickel alloy phase or a copper alloy phase as described above. Nickel alloys and copper alloys have a higher specific gravity than cast iron materials, which makes it difficult for the pellets to be separated from the molten metal.

ペレットの比重は、ニッケル合金及びセラミックス粉末の種類及び割合を調整することで制御することができる。例えば、ニッケル合金にTiCを40体積%含有させたペレットの比重は7.1であり、鋳鉄溶湯の比重と略同等となる。   The specific gravity of the pellet can be controlled by adjusting the kind and ratio of the nickel alloy and the ceramic powder. For example, the specific gravity of a pellet in which 40% by volume of TiC is contained in a nickel alloy is 7.1, which is substantially equal to the specific gravity of the molten cast iron.

次に、第2工程において、上記したペレットを鋳鉄溶湯に添加する。鋳鉄溶湯に添加されたペレットは、ペレットのまま、又は表層が溶解した状態で鋳鉄溶湯中に分散する。しかも、ペレットの比重が鋳鉄溶湯の比重と略同等であるので、ペレットが鋳鉄溶湯から分離することが回避される。   Next, in the second step, the above pellets are added to the molten cast iron. The pellets added to the cast iron melt are dispersed in the cast iron melt in the form of pellets or with the surface layer dissolved. Moreover, since the specific gravity of the pellet is substantially equal to the specific gravity of the molten cast iron, it is avoided that the pellet is separated from the molten cast iron.

このように、ペレットと鋳鉄溶湯との比重を略同等とすることにより、ペレットが鋳鉄溶湯から分離することを抑制することができる。   Thus, it can suppress that a pellet isolate | separates from a cast iron molten metal by making the specific gravity of a pellet and a cast iron molten metal substantially the same.

ペレットを鋳鉄溶湯に添加した後、次なる第3工程において、該鋳鉄溶湯が凝固される。この凝固の際、引け巣の発生が抑制される。   After the pellets are added to the cast iron melt, the cast iron melt is solidified in the next third step. During this coagulation, the generation of shrinkage nests is suppressed.

凝固が終了すると、ペレットに含まれたセラミックス相を含む複合材が鋳造品として得られる。この複合材は、セラミックス相を含むことに起因して、該複合材の母材である金属材に比して大きなヤング率を示す。   When solidification is completed, a composite material containing the ceramic phase contained in the pellet is obtained as a cast product. This composite material includes a ceramic phase, and thus exhibits a larger Young's modulus than the metal material that is the base material of the composite material.

ヤング率が大きなものは、剛性も大きい。すなわち、本実施の形態によれば、母材の金属材に比して剛性が大きな複合材を容易に得ることができる。   A material having a large Young's modulus has a large rigidity. That is, according to the present embodiment, it is possible to easily obtain a composite material having higher rigidity than the metal material of the base material.

次に、第2実施形態について説明する。   Next, a second embodiment will be described.

第2実施形態に係るペレットは、鋳鉄に代替して鋳鋼を母材とし、且つ比重が7.6〜8.4である点を除いて、上記第1実施形態と同様である。また、その製造方法も、鋳鉄溶湯に代替して鋳鋼溶湯を用いればよい。   The pellet according to the second embodiment is the same as the first embodiment except that cast iron is used as a base material instead of cast iron and the specific gravity is 7.6 to 8.4. Moreover, the manufacturing method should just use a cast steel melt instead of a cast iron melt.

なお、ペレットの比重を変更するには、例えば、ペレット中のセラミックス相及び金属相の組成比を変更すればよい。第1実施形態と同様にニッケル合金にTiCを含有させる場合、その割合を20体積%とすれば、比重が7.9であり、鋳鋼溶湯の比重と略同等であるペレットが得られる。   In order to change the specific gravity of the pellet, for example, the composition ratio of the ceramic phase and the metal phase in the pellet may be changed. When TiC is contained in the nickel alloy as in the first embodiment, if the ratio is 20% by volume, a specific gravity of 7.9 is obtained, and a pellet substantially equal to the specific gravity of the molten cast steel is obtained.

ここで、金属相を鋼材、ニッケル、銅、セラミックス相をTiC、SiCとしてその添加量を種々変更することで比重が異なるペレット(添加材)を作製し、このペレットを鋳鉄溶湯又は鋳鋼溶湯に添加した際のペレットの分散具合を図1に示す。図1中、「×」はペレットが溶湯の界面に浮上したり、鉛直方向に沿って偏析したりして分散具合が良好でなかったことを表し、「○」はペレットが良好に分散した複合材が得られたことを表す。   Here, the metal phase is steel, nickel, copper, the ceramic phase is TiC, SiC, and various addition amounts are used to produce pellets (additives) with different specific gravity, and this pellet is added to the cast iron melt or cast steel melt FIG. 1 shows how the pellets are dispersed. In FIG. 1, “×” indicates that the pellet floated at the molten metal interface or segregated along the vertical direction, and the dispersion was not good, and “◯” represents the composite in which the pellet was well dispersed. Indicates that the material was obtained.

この図1から、ペレットの比重を溶湯の比重に近似させることで、良好な複合材を得られることが分かる。   It can be seen from FIG. 1 that a good composite material can be obtained by approximating the specific gravity of the pellet to the specific gravity of the molten metal.

また、図2は、ニッケル又は銅にTiCが50体積%添加されたペレット、ニッケルにVCが60体積%添加されたペレットを鋳鉄溶湯又は鋳鋼溶湯に添加して得られた複合材、FCD450相当材、SC450相当材の各ヤング率の測定結果を併せて示した。この図2から、セラミックス相を含有したペレットを添加することで、鋳鉄材ないし鋳鋼材に比してヤング率が著しく大きな複合材が得られることが明らかである。   FIG. 2 shows a composite material obtained by adding 50% by volume of TiC to nickel or copper, and a pellet obtained by adding 60% by volume of VC to nickel to cast iron or cast steel, FCD450 equivalent material The measurement results of each Young's modulus of the SC450 equivalent material are also shown. From FIG. 2, it is clear that a composite material having a remarkably large Young's modulus compared to cast iron or cast steel can be obtained by adding a pellet containing a ceramic phase.

なお、複合材の母材をいわゆる特殊鋳鉄材や特殊鋼材とするべく、他の金属元素をさらに添加してペレットを構成するようにしてもよい。   In order to make the base material of the composite material a so-called special cast iron material or special steel material, another metal element may be further added to form a pellet.

各種ペレットを鋳鉄溶湯又は鋳鋼溶湯に添加したときの分散度合を表す図表である。It is a chart showing the dispersion degree when various pellets are added to cast iron melt or cast steel melt. 本実施の形態に係る複合材と、FCD450相当材、SC450相当材の各ヤング率の測定結果である。It is a measurement result of each Young's modulus of the composite material which concerns on this Embodiment, a FCD450 equivalent material, and a SC450 equivalent material.
