Definitions
- the present invention relates to a friction welding method suitable for joining metal members.
- Friction welding has been proposed as one method for joining metal members.
- Friction welding is a method in which joining surfaces of metal members to be joined are brought into contact with each other, mechanically moved relative to each other while pressing the joining surfaces, and the generated frictional heat is used as a heating source.
- the relative motion of the member includes, for example, a rotational motion around an axis perpendicular to the contact surface, and a reciprocating motion in a direction parallel to the contact surface. Since friction welding does not use current heating, a large power supply facility is not required, and a product with high dimensional accuracy can be obtained with a relatively simple facility. For this reason, it is applied to joining of parts subjected to finish processing. Further, unlike general welding, joining between dissimilar metal materials is possible, so that the application fields are wide. Therefore, it is applied to many precision machine parts such as valves for automobiles.
- Friction welding requires heating to near the melting point of the metal member and adhesion by plastic flow near the joint surface. Therefore, deformation is likely to occur in the vicinity of the joint surface, and the heat-affected zone of the metal member is widened, which has an adverse effect on the strength and material characteristics. For this reason, various methods have been proposed as a method for controlling the thermal effect of the metal member.
- Patent Document 1 when metal members having different heat capacities are friction-welded, an insert material as a rotating body is inserted between the metal members, and the temperature of both members is individually controlled, and the insert material is rotated and friction bonded. A method is disclosed. In the friction welding method of patent document 1, a pair of metal member can be joined via an insert member.
- Patent Document 2 proposes that an amorphous alloy foil (a brazing material for brazing) used for liquid phase diffusion bonding is previously bonded to a metal member by a friction welding method in order to reduce the bonding temperature. Yes. That is, the friction welding that is the primary bonding can be performed at a temperature below the melting point of the brazing material (amorphous metal foil), and the liquid phase diffusion bonding (brazing) that is the secondary bonding is the brazing material (amorphous metal foil). ) At about the melting point. Therefore, since the temperature can be lowered as compared with normal friction welding, the amount of deformation is small, and the heat-affected zone of the metal member can be reduced. However, the method of Patent Document 2 is essentially a liquid phase diffusion bonding of metal members and is not a friction welding.
- An oxide (a metal oxide including a natural oxide film and originating from the base material, hereinafter simply referred to as an oxide) exists on the joint surface of the metal member to be joined.
- an oxide a metal oxide including a natural oxide film and originating from the base material, hereinafter simply referred to as an oxide
- solid phase bonding such as friction welding is performed, it is important to remove oxide from the bonding surface. This is because if the oxide remains in the bonding interface, the portion becomes a defect and the bonding strength decreases. Furthermore, the oxide may become a source of cracks and may significantly deteriorate fracture toughness.
- Non-patent Document 1 Since the melting point of general low carbon steel is about 1400 ° C. to 1500 ° C., it can be seen that the temperature is very high. When heating at a high temperature in this way, it takes time to generate sufficient frictional heat, and it is difficult to shorten the joining time.
- HAZ Heat Affected Zone
- the softened area by high-temperature heating causes plastic flow due to upset pressurization (pressing) and is discharged to the outside.
- the softened region is widened when the heating temperature of the joint is high, a wide range around the joint is plastically flowed, and not only the amount of deformation increases but also the amount of burrs increases. For this reason, the accuracy of the final product is deteriorated, and processing such as burr removal (cutting processing, etc.) is required, resulting in extra labor and cost.
- This phenomenon is not limited to steel, and the same thing occurs with metal materials such as aluminum, titanium, and copper.
- the present invention has been made in order to solve such problems.
- In the friction welding of metal members it is possible to obtain sufficient bonding strength in a short time while eliminating the adverse effects of high-temperature heating as in the past. Let it be an issue.
- the melting point of the insert material is preferably about 50 ° C. lower than the heating temperature (pressure welding temperature) necessary for joining. This is because if the melting point of the insert material is lower than necessary, the insert material is pushed out before the oxides are peeled off.
- the melting point of the metal material varies depending on the material, it has been found that the melting point of the insert material can be approximated by a ratio with the melting point (degrees Celsius) of the metal member. That is, it has been found that the melting point of the insert material may be selected to be 60% to 80% of the melting point (degrees Celsius) of the metal member (degrees Celsius).
- the present invention has been made based on these findings, and the gist thereof is as follows.
- a friction welding method for a pair of metal members wherein a melting point of 60 to 80% of the melting point (degrees Celsius) of the metal member is provided between the joining surfaces of the metal members facing each other. Friction welding is started in a state where an insert material made of metal having a temperature of Celsius is sandwiched, the insert material is melted, and the insert material is pushed out between the pair of metal members, that is, the melted insert material is joined to the opposite side.
- a friction welding method characterized by extruding from between the surfaces.
- the friction welding of metal members eliminates the disadvantages caused by high-temperature heating as in the conventional case, can be joined in a short time, and a joining strength equal to or higher than that of the conventional case can be obtained.
- the friction welding method according to the present invention is a method of performing friction welding in a state where an insert material is sandwiched between a pair of metal members.
- the opposing and joined surfaces of the pair of metal members are called joined surfaces.
- what joined a pair of metal member is called a joining material.
- the vicinity of the bonding interface of the bonding material is called a bonded portion.
- a temperature related item indicates a Celsius temperature (° C.) unless otherwise specified.
- FIG. 1 is a diagram for explaining a friction welding method according to an embodiment of the present invention.
- FIG. 1 shows the case where the cylindrical metal members 1 and 2 are joined, the shape of the friction welding method according to the present invention is not particularly limited, and other shapes (for example, cylindrical) It can also be applied to the joining of steel materials having a shape, prismatic shape, etc.).
- the insert material 3 is made of a metal whose melting point is 60% to 80% of that of the metal members 1 and 2 at a Celsius temperature.
- any metal having a melting point of about 900 ° C. to 1200 ° C. with respect to the melting point of steel (about 1500 ° C.) may be used.
- the material of the insert material 3 include Cu, Fe, Ni, and Au-based alloys.
- the thickness of the insert material 3 is preferably 10 to 500 ⁇ m, for example.
- the insert material preferably covers the joint surface of at least one of the metal members.
- the metal member 1 is held by a rotation holding portion (not shown) of a friction welding device (not shown), and the metal member 2 is a fixed portion (not shown) of the friction welding device (not shown). Z).
- the metal member 1 is lightly pressed against the metal member 2 through the insert material 3 so that the insert material 3 is sandwiched between the metal members 1 and 2.
- the insert material 3 may be attached to the joint surface of the fixed metal member 2 with an adhesive or the like. In this state, friction welding is started.
- the friction welding method of the present invention can be carried out using a known friction welding device or a device obtained by adding a simple design change to a known friction welding device, and therefore a detailed description of the friction welding device is omitted.
- the metal member 1 is moved in the axial direction while rotating at high speed and pressed against the steel material 2 through the insert material 3.
- the insert material 3 rotates relative to both members while being held by receiving pressure from the metal members 1 and 2.
- frictional heat is generated at the contact portion between the steel material 1 and the insert material 3 and at the contact portion between the steel material 2 and the insert material 3.
- the insert material 3 is heated and melted by this frictional heat.
- the rotation speed and pressing force of the metal member 1 are determined according to the dimensions and materials of the steel materials 1 and 2 and the insert material 3, the type of the friction welding apparatus, and the like.
- the metal member when it is steel, it may be set as appropriate within the range of a rotational speed of 1000 to 4000 rpm and a pressing force of 30 to 300 MPa. In this embodiment, only the metal member 1 is rotated, but both members may be rotated. In that case, it is preferable to reversely rotate the metal members 1 and 2 because the relative rotational speed increases.
- the relative movement is not limited to rotation, and may be linear reciprocation. The mode is not limited as long as it is a motion form in which frictional heat is generated.
- the molten insert material 3 is extruded from between the metal members 1 and 2, and the metal member 1 and the metal member 2 are moved together. Join by direct contact. At this time, the oxide on the joint surfaces of the metal members 1 and 2 is peeled off and discharged to the outside together with the melted insert material.
- an oxide is present on the joint surface of the metal member.
- Fe 2 O 3 and SiO 2 and MnO which are oxides of Si and Mn in the steel, are present on the joint surface.
- Al 2 O 3 si-called alumina
- This oxide is peeled from the metal member due to high temperature and rotational force (force by relative motion) or is easily peeled off. Since the melted insert material flows so as to be pushed out by pressing, the oxide on the joint surface is pushed out as well.
- the contact surfaces having high cleanliness without impurities such as insert material and oxide are brought into contact with each other, a good bonding material with high bonding strength can be obtained.
- the temperature of the joint at this time is about 50 ° C. higher than the melting point of the insert material, it is lower than the temperature in the conventional friction welding, but is sufficient to obtain adhesion.
- the insert material 3 discharged from the joining surface is removed, and the joining material composed of the metal members 1 and 2 is completed. Although the temperature is lower than that of the conventional friction welding, there can be obtained a bonding material having no defect and high bonding strength.
- the oxide was discharged to the outside by plastic flow of the metal member itself, a considerable amount of plastic flow of the metal member was necessary.
- the discharge of oxide is left to the molten insert material, so that the flow amount of the metal member itself does not occur or may be relatively small. Therefore, the deformation of the metal member can be suppressed, and the finished accuracy of the finished bonding material can be increased.
- this can prevent the wide range of the metal members 1 and 2 from becoming high temperature, so that HAZ can be prevented from being formed in a wide range around the joint.
- the HAZ softened region is also reduced, and a decrease in strength as a bonding material can be suppressed.
- the insert material according to the present invention will be described by taking the case where the metal member is steel as an example.
- the bonding surface temperature is about 1000 ° C., adhesion becomes easy, and the bonding strength (bonding strength) is improved (Non-Patent Document 1).
- the temperature necessary for this pressure welding is called pressure welding temperature here. It has been found that the pressure welding temperature has some correlation with the melting point. In our research, it was confirmed that S15C steel (melting point: about 1500 ° C.) can be sufficiently joined at an insert melting point of 900 ° C. and a pressure welding temperature of 950 ° C.
- the melting point of the insert material was 60% of the melting point of steel, and the pressure welding temperature was 63%.
- the pressure welding temperature was measured by embedding a thermocouple in the vicinity of the bonding interface at the center of the bonded body on the fixed chuck side.
- the heating temperature of the joint surface reaches 1300 to 1400 ° C. (Non-patent Document 1). That is, it reaches about 90% of the melting point of steel. It can be seen how hot the conventional method was.
- the heating temperature of the bonding surface needs to be lower than the conventional heating temperature, it is preferable to make it lower than 1300 ° C. By doing so, the heating time can be shortened, the HAZ width can be suppressed, and the adverse effects caused by the high temperature can be eliminated.
- the melting point of the insert material is preferably 900 ° C. to 1200 ° C.
- the heating temperature (pressure welding temperature) of the joining surface should be about 50 ° C. higher than the melting point of the insert material. I found out.
- the melting point of a metal such as steel varies depending on its composition.
- the pressure welding temperature is also lowered, and the maximum heating temperature of the joint surface must be lowered.
- the pressure welding temperature has a certain degree of correlation with the melting point, and can be considered to be approximately proportional. Therefore, in the present invention, the melting point of the insert material is indicated by the ratio to the melting point of the metal member.
- the melting point is about 1500 ° C.
- the melting point of the insert material is preferably set to 60% to 80% of the melting point of the metal member as the base material.
- the joint surface temperature (pressure welding temperature) at the time of pressure welding so that it may become about 50 degreeC higher than melting
- the melting point is about 1150 ° C.
- the pressure welding temperature also decreases. Even in that case, an insert material having a melting point of 700 ° C. corresponding to 60% of the melting point of steel as a base material can be applied, and friction welding can be performed at a pressure welding temperature of 750 ° C.
- the pressure welding temperature is preferably set to 70 ° C. or more, more preferably 80 ° C. or more of the melting point of the insert material.
- the upper limit of the pressure welding temperature is not particularly set, but is at most about 90% of the melting point of the metal member similar to the conventional one even if it is high.
- the material of the insert material is not particularly limited, but can be obtained by adjusting the melting point from Cu, Fe, Ni, Au-based alloy or the like.
- a brazing material can be applied.
- Ni-3.5% Si-8% B-11% V alloy (melting point: 1073 ° C.)
- Fe-2.5% Si-12% B-8% V alloy (melting point: 1122 ° C.)
- Ni— A 0.8% Si-15% P-7% V alloy (all in Patent Document 2).
- the insert material also softens when heated to about its melting point, and plastically flows when pressed. Therefore, when the thickness of the insert material is too thin, the joining surfaces of the metal members come into contact with each other before reaching the melting point of the insert material, and there is a possibility that the insert material disappears between the joining surfaces. For this reason, the thickness of the insert material is preferably 10 ⁇ m or more. From the viewpoint of handleability and manufacturability, it is preferably 25 ⁇ m or more, more preferably 50 ⁇ m or more.
- the thickness of the insert material is preferably 500 ⁇ m or less. Since the effect of shortening the heating time by reducing the thickness is great, the thickness is preferably 300 ⁇ m or less, more preferably 150 ⁇ m or less.
- the shape of the insert material is not particularly limited.
- the insert material melts and is extruded from the joint surface, there is no problem as long as it passes through the entire joint surface. This is because if there is a portion where the insert material does not pass through even part of it, the oxide in that portion may not be removed. Therefore, from the viewpoint of enhancing the effect of discharging the oxide on the joint surface of the metal member, it is preferable that the size is such that at least one joint surface can be covered. Thereby, the insert material can fill the entire joint surface, and the oxide on the joint surface can be reliably discharged.
- Metals other than steel mainly include alloys such as Al, Ti, and Cu.
- steel was used as the metal member.
- the steel materials and insert materials used in the experiment are shown below.
- Two steel materials are prepared, one on the same axis is set on the fixed chuck, the other is set on the rotating chuck, the chuck is moved in the axial direction, and the insert material is sandwiched between the two steel materials (FIG. 1). (See (a)). Thereafter, the rotating chuck was rotated, and the chuck was moved so as to press both steel materials (see FIG. 1B). The number of rotations at that time was fixed at 1800 rpm, and the bonding was performed at a friction pressure of 200 MPa, a friction time of 3 s (s indicates second, the same applies hereinafter), an upset pressure of 300 MPa, and an upset time of 3 s.
- a tensile test was performed using a joining material (a steel material in which both steel materials were joined together), and an evaluation was made based on a breaking strength ratio (breaking strength / base material strength) and a breaking portion. Further, as a comparative example, the same steel material was used, and conventional friction welding was performed without using an insert material. In Comparative Example 1, the friction time was 2 s, and in Comparative Example 2, the friction time was 3 s. The other conditions were the same as when the insert material was added. The test results are shown in Table 1.
- Example and Comparative Example 1 since the fracture occurred at other than the bonding interface, it seems that the bonding itself was good.
- the distance from the joint interface to the HAZ most softened portion in the example was about 1.5 mm, whereas in Comparative Example 1, it was about 3 mm. That is, it was confirmed that the HAZ width in the example was narrowed.
- the embodiment of the friction welding method according to the present invention is not limited to the above-described embodiment.
- the present invention even when metal members such as steel are joined together, joining can be performed at a low temperature, and joining quality equal to or higher than that in the past can be obtained. Therefore, the present invention can be used for manufacturing precision machine parts.

Abstract
Description
部材の相対運動は、例えば接触面に垂直な軸を中心とした回転運動や、接触面に平行な方向の往復運動などがある。摩擦圧接は、通電加熱を利用しないため、大きな電源設備を必要とせず、比較的簡単な設備で寸法精度の高い製品が得られる。このことから、仕上げ加工を施した部品の接合などに適用される。また、一般的な溶接とは異なり異種金属材料間の接合も可能であるため、応用分野が広い。そのため、自動車用のバルブなど、多くの精密機械部品などに適用されている。
(a)金属部材の摩擦圧接方法において、金属部材より融点の低いインサート材を金属部材の間に配置して摩擦圧接を実施した際に、溶融したインサート材の流動とともに、接合面の酸化物(酸化皮膜)を除去できることを見出した。これにより、金属部材を必要以上に加熱することなく、インサート材が溶融すれば金属部材の接合面に存在する酸化物(酸化皮膜を含む。)を除去することができる。
すなわち、接合面の相対的運動(例えば回転運動等)により、接合面上の酸化物が剥離され、若しくは剥離され易い状態になり、これに加え、溶融したインサート材の流動により、この剥離した酸化物がこそぎ取られ、そして押し流されるものと考えられる。これにより、接合面の清浄度を著しく高めることができ、欠陥のない接合界面を得ることができる。
(1)一対の金属部材の摩擦圧接方法であって、前記金属部材の対向し接合される面である接合面の間に、前記金属部材の融点(摂氏温度)の60~80%の融点(摂氏温度)を有する金属からなるインサート材を挟持した状態で摩擦圧接を開始し、前記インサート材を溶融させ、前記一対の金属部材の間から押し出すこと、すなわち溶融した前記インサート材を前記対向する接合面の間から押し出すこと、を特徴とする摩擦圧接方法。
(2)前記インサート材の厚さが10~500μmであることを特徴とする(1)に記載の摩擦圧接方法。
(3)前記インサート材が、少なくとも一方の前記接合面をカバーすることを特徴とする(1)または(2)に記載の摩擦圧接方法。
(4)圧接時の温度が、前記インサート材の融点(摂氏)より50℃以上高いことを特徴とする(1)~(3)のいずれか1項に記載の金属部材の摩擦圧接方法。
(5)摩擦圧接後に、前記金属部材間に前記インサート材が残留していないことを特徴とする(1)~(4)のいずれか1項に記載の金属部材の摩擦圧接方法。
(6)前記金属部材が鋼であることを特徴とする(1)~(5)のいずれか1項に記載の金属部材の摩擦圧接方法。
その後、接合面から排出されたインサート材3を除去し、金属部材1、2からなる接合材が完成する。従来の摩擦圧接よりは低い温度でありながら、欠陥がなく、接合強度の高い接合材を得ることができる。
本発明に係るインサート材について、金属部材が鋼の場合を例にして説明する。
[インサート材の融点]
鋼の場合、接合面温度が1000℃程度で、密着が容易になり、結合力(接合強度)が向上することが知られている(非特許文献1)。この圧接に必要な温度を、ここでは圧接温度とよぶ。圧接温度は、融点とある程度相関があることが分かっている。発明者らの研究では、S15C鋼(融点:約1500℃)で、インサート材融点900℃、圧接温度950℃で、十分接合できることを確認した。即ち、インサート材の融点は、鋼の融点の60%であり、圧接温度は63%であったことになる。なお、圧接温度は、固定チャック側の接合体中心部の接合界面近傍に熱電対を埋め込んで測定した。一方、従来の摩擦圧接では、接合面の加熱温度は1300~1400℃に達する(非特許文献1)。即ち、鋼の融点の90%程度に達する。従来の方法は、いかに高温であったかが分かる。
インサート材もその融点程度に加熱すると軟化し、押圧することにより塑性流動する。したがって、インサート材の厚さが薄過ぎると、インサート材の融点に達する前に金属部材の接合面同士が接してしまい、接合面間にインサート材がなくなる可能性がある。このため、インサート材の厚さは10μm以上とするとよい。取扱い性、製造可能性などの観点から、好ましくは25μm以上、さらに好ましくは50μm以上とするとよい。
インサート材の形状は特に限定しない。インサート材が溶融し、接合面から押し出される際に、接合面全体を通過するものであれば問題ない。一部でもインサート材が通過しない部分があると、その部分の酸化物が除去されないおそれがあるからである。そのため、金属部材の接合面上の酸化物の排出効果を高める観点から、少なくとも一方の接合面をカバーできる大きさにすることが好ましい。これにより、インサート材が接合面全体に充満することができ、接合面上の酸化物を確実に排出することができるからである。
以上の知見は、鋼以外の金属にも適用でき、融点を基準にすれば概ね同じ数値範囲なることを確認した。鋼以外の金属は、主にAl、Ti、Cuなどの合金が挙げられる。
鋼材: Fe-0.45%C-0.2%Si-0.7%Mn
融点:約1440℃
直径20mm×長さ100mmの円柱形
両端面は機械加工による平面に仕上げ
インサート材:Cu-35%Zn合金
融点:930℃
直径 22mm×厚さ100μm(0.1mm)の円盤状
また、比較例として、同じ鋼材を用いて、インサート材を入れずに従来の摩擦圧接を行った。比較例1は摩擦時間2sとし、比較例2では摩擦時間3sとした。その他の条件はインサート材を入れた場合と同条件とした。
試験結果を表1に示す。
