本発明は組合せ摺動部材に関し、詳（７〈は両方の母材
がアルミニウム合金（以下「アルミ合金」と略称する）
でなる組合せ摺動部材に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a combination sliding member.
The present invention relates to a combination sliding member consisting of the following.
（従来の技術）
自動車等に用いられる摺動部材は軽量化を計るために母
材としてアルミ合金を用いることが要請されている。と
ころでアルミ合金自体は、摺動部材として使用するには
耐摩耗性が劣るという欠点を有している。この欠点を補
う方法として陽極酸化処理により、表面にアルマイト層
を形成させることが知られている（「機械設計」第２９
巻第１５号、７７〜８６頁、１９８５年）。(Prior Art) In order to reduce the weight of sliding members used in automobiles and the like, aluminum alloys are required to be used as the base material. However, aluminum alloy itself has a drawback of poor wear resistance when used as a sliding member. As a method to compensate for this drawback, it is known to form an alumite layer on the surface by anodizing treatment ("Mechanical Design" No. 29).
Vol. 15, pp. 77-86, 1985).
このアルマイト層を形成させたもの（以下「アルマイト
材」という）は母材がアルミニウム合金であるにも拘わ
らず耐摩耗性がかなシ向上する。Materials on which this alumite layer is formed (hereinafter referred to as "alumite materials") have significantly improved wear resistance even though the base material is an aluminum alloy.
しかし一対の組合せ摺動部材の両方ともにアルマイト層
を形成させると、同種材が摺動することとなるため摩耗
が多くなり、むしろアルマイト材とアルミ合金母材から
なる組合せ摺動部材の方が摩耗が少ない。However, if an alumite layer is formed on both of a pair of combined sliding members, the same type of material will be sliding, resulting in more wear.In fact, the combined sliding member made of anodized material and aluminum alloy base material will wear more. Less is.
そのため、従来の軽量摺動部材としては、陽極酸化処理
によりアルマイト層を形成させたアルミ合金をボディ側
部材とし、耐摩耗性に優れた鋼や熱処理式れ次鋼をバル
ブ側部材とした組合せ摺動部材が用いられている。Therefore, conventional lightweight sliding members are made of a combination of an aluminum alloy with an anodized layer formed by anodizing treatment used as the body side member, and a steel with excellent wear resistance or heat-treated steel as the valve side member. Moving parts are used.
（発明が解決しようとする問題点）
し、かじながら該組合せ摺動部材がピストン型式で使用
されるとなると、潤滑油の温度変化によって生じる以下
のような問題があった。(Problems to be Solved by the Invention) However, when the combined sliding member is used in a piston type, the following problems occur due to temperature changes in the lubricating oil.
即ち、ボディ側（アルミニウム合金＋アルマイト層）と
バルブ側（鉄系材）とでは熱膨張係数が異なるために、
低温時には摺動部位のクリアランスが小さくなりスティ
ック（バルブ摺動不良）が発生し、また高温時にはクリ
アランスが大きくなって油洩れが発生するという問題が
おった。更に、高温で使用された後に放冷されることに
よって、潤滑油回路中の異物がバルブとボディ間に残り
、スティック奮起こすという問題もあった。In other words, since the coefficient of thermal expansion is different between the body side (aluminum alloy + alumite layer) and the valve side (ferrous material),
At low temperatures, the clearance of the sliding parts becomes small, causing sticking (defective valve sliding), and at high temperatures, the clearance increases, causing oil leakage. Furthermore, when the valve is left to cool after being used at high temperatures, there is a problem in that foreign matter in the lubricating oil circuit remains between the valve and the body, causing it to stick.
その対策として、ボディ側、バルブ側ともに熱膨張係数
が出来るだけ同じである部材を用いればよいことは勿論
であシ、そのためバルブ側にもアルマイト材を用いるこ
とが考えられ、一部実用化されている。この組合せによ
ると上記のクリアランス変化等による不具合は発生し７
ないが、前述し九通りアルマイト層どうしの摺動では耐
摩耗性罠劣るという問題がある。As a countermeasure to this, it is of course best to use materials with the same coefficient of thermal expansion as possible for both the body side and the valve side. Therefore, it is possible to use an alumite material for the valve side as well, and some have been put into practical use. ing. With this combination, the above-mentioned problems due to changes in clearance etc. will not occur.7
However, as mentioned above, there is a problem in that the alumite layers slide against each other in terms of wear resistance.
ところでアルミニウム系部材の耐摩耗性の向上方法とし
ては、前記の陽極酸化処理（アルマイト化）の他に次の
方法が知られている。By the way, as a method for improving the wear resistance of aluminum-based members, in addition to the above-mentioned anodizing treatment (alumitization), the following method is known.
■ Ｆｅ（鉄）メッキを施して表面を硬化する方法（日

First edition, p. 27o), ■ A method of applying electrolytic RI to one aluminum alloy and forming a Fe-P (iron-phosphorus alloy) plating film on the other aluminum alloy (Japanese Patent Laid-Open No. 58-146
(See No. 765).

A method of forming (see Japanese Patent Application Laid-Open No. 60-165589).
しかしこれらの方法はある程度の改善効果はみられるも
のの決して満足できるものではない。However, although these methods show some improvement effects, they are by no means satisfactory.

で自身及び相手材とも摩耗が多くなる。また荷重の高い

生して異物が入った場合と同じ、現象が現われ焼付荷重
が低下する。By the way, when using a high-silicon aluminum alloy (standard: A390), which has good wear resistance among aluminum alloys, the friction is the primary silicon crystal in the aluminum alloy structure: 17 (HV900 ~
1100) and the mating material (Fe-plated material), the wear of the mating material increases, and as the surface roughness increases, the wear of both itself and the mating material increases. Furthermore, when used in a high load area, the same phenomenon occurs as when primary silicon cracks or falls off and foreign matter enters, and the seizure load decreases.
本発明は上記諸問題を解決する友めになされた吃ので、
その目的とするところは、温度によるクリアランス変化
を来たさない共に母材がアルミ合金でなる組合せ摺動部
材であって、しかも耐摩耗性、耐焼付性の優れた組合せ
摺動部材を提供することである。The present invention has been made to solve the above-mentioned problems.
The purpose is to provide a combined sliding member whose base material is made of aluminum alloy, which does not cause clearance changes due to temperature, and which has excellent wear resistance and seizure resistance. That's true.
（問題点を解決するための手段）
上記目的全達成し得る本発明の組合せ摺動部材は、共に
アルミニウム合金を母材とする一対の摺動部材であって
、一方の部材の摺動面にアルマイト層が形成され、他方
の部材の摺動面には樹脂コーティング層が形成されてい
ることを特徴とする。(Means for Solving the Problems) The combined sliding member of the present invention that can achieve all of the above objects is a pair of sliding members both made of aluminum alloy as a base material, and the sliding surface of one member is It is characterized in that an alumite layer is formed, and a resin coating layer is formed on the sliding surface of the other member.
本発明は上記のように組合せると驚ろくべきことに従来
に比べ耐摩耗性、耐焼付性が格段に向上した摺動部材と
な夛得ることを知見しな嘔ｉ念もので、以下に更に詳し
く説明する。We regret not to have known that when the present invention is combined as described above, a sliding member with surprisingly improved wear resistance and seizure resistance compared to the past can be obtained. It will be explained in more detail.
一方の部材であるアルマイト層形成部材は常法に従い、
アルマイト層を形成し得るアルミ合金を電解浴１例えば
硫酸浴、シェラ酸浴、これらの混酸浴等を用い、陽極側
で処理することにより得られる。このアルマイト層の硬
さはＨｖ１５０以上であればよい。それ以下ではアルマ
イト層の摩耗が増加する。One of the members, the alumite layer forming member, was prepared using a conventional method.
It is obtained by treating an aluminum alloy capable of forming an alumite layer on the anode side using an electrolytic bath 1 such as a sulfuric acid bath, a Scherer's acid bath, or a mixed acid bath thereof. The hardness of this alumite layer should just be Hv150 or more. If the temperature is lower than that, wear of the alumite layer increases.
他方の部材に形成される樹脂コーティング層としては、
優れた摺動特性、耐摩耗性、耐焼付性を付与しえるもの
が選ばれるべきで、そのための樹脂としてはポリイミド
樹脂、フェノール樹脂、四フッ化エチレン樹脂、ポリア
ミド樹脂等を用いることができる。特には機械的及び熱
的に高強度なポリイミド樹脂が好ましい。また上記各樹
脂に安定剤や硬化剤を混入したものは勿論、二硫化モリ
ブデン、グラファイト、四フッ化エチレン樹脂等の潤滑
材料全配合したものを用いてもよい。As the resin coating layer formed on the other member,
A resin that can provide excellent sliding properties, abrasion resistance, and seizure resistance should be selected, and examples of resins for this purpose include polyimide resins, phenol resins, tetrafluoroethylene resins, and polyamide resins. In particular, polyimide resins with high mechanical and thermal strength are preferred. In addition, it is also possible to use not only the above-mentioned resins mixed with stabilizers and curing agents, but also those containing all lubricating materials such as molybdenum disulfide, graphite, and tetrafluoroethylene resin.
樹脂コーティング層の厚さとしては５〜１００μ程度が
好ましい。これは５μ以下では耐久性（耐摩耗性）が不
足し１片や１００μ以上では高温時に樹脂の膨張が問題
になるとともにコーティングコストが高くなるためであ
る。The thickness of the resin coating layer is preferably about 5 to 100 microns. This is because if it is less than 5μ, the durability (wear resistance) is insufficient, and if it is one piece or more than 100μ, resin expansion becomes a problem at high temperatures and the coating cost increases.
樹脂コーティング層の形成は常法に従がって行なうこと

Ｌでいる各種の方法１例えば塗布法、流動浸漬法、静電

ーティングし、必要に応じて機械加工を施せばよい。The resin coating layer can be formed according to a conventional method. That is, it is known as a method of repeating resin on metal surfaces.
Various Methods 1: For example, the aluminum alloy may be coated with a resin material by a coating method, a fluidized dipping method, an electrostatic spraying method, a thermal spraying method, etc., and then machined if necessary.
本発明の組合せ摺動部材の母材である両アルミ合金の熱
膨張係数差は４Ｘ１０ ／℃ＩＪ下であるのが好まＬ
７い。これ以上では高温（１５０℃）で使用し放冷し念

掻き痕を生じさせるがスティックが発生することはない
からである。It is preferable that the difference in thermal expansion coefficient between the two aluminum alloys that are the base materials of the combined sliding member of the present invention is less than 4X10/℃IJ.
7. If it is used at a high temperature (150℃) and left to cool, foreign matter in the lubricating oil circuit will remain between the body and the valve and may easily cause stick 1.
In the following, even if foreign matter remains, it will cause some scratch marks between the body and the valve, but no stick will occur.
従って木組合せ摺動部材はピストン型式の摺動部材とし
て、特にはオートマチックトランスミッションの油路切
替装置のボディ及びバルブ用の組合せ摺動部材として好
適である。Therefore, the wood combination sliding member is suitable as a piston-type sliding member, particularly as a combination sliding member for a body and a valve of an oil path switching device of an automatic transmission.
