This problem is solved by a combination sliding member. Specifically, the problem is solved by a combination sliding member comprising a first sliding part that is made from aluminum or an aluminum alloy and a second sliding part that is made from a steel material, said combination sliding member being characterized in that: a surface of the second sliding part that slides on the first sliding part has a manganese phosphate coating that contains copper; in the manganese phosphate coating, the manganese content is not less than 1.5 g/m2 and the copper/manganese content ratio is 0.02-2.56; and the surface roughness Ra of a surface of the first sliding part that slides on the second sliding part is not more than 2.9 μm.
Description
本発明は、摺動部材に関するものであり、特に、互いに摺動する複数の摺動部材を含む組み合わせ摺動部材に関する。組み合わせ摺動部材には、例えば、転がり軸受とハウジングなどが含まれる。
The present invention relates to a sliding member, and more particularly to a combination sliding member including a plurality of sliding members that slide against each other. Combination sliding members include, for example, rolling bearings and housings.
従来、例えば、バルブとバルブボディ等のように、硬度の異なる材料で形成された部材を含む組み合わせ摺動部材が利用されている。このような組み合わせ摺動部材として、たとえば、摺動面にアルマイト層が形成されているアルミニウム合金からなる第1摺動部品と、該第1摺動部品の摺動面に摺動し、所定の高分子樹脂、強化繊維および固体潤滑剤からなる第2摺動部品とを備えた組み合わせ摺動部材(特許文献1)などが知られている。
Conventionally, a combination sliding member including members formed of materials with different hardness, such as a valve and a valve body, has been used. As such a combined sliding member, for example, a first sliding component made of an aluminum alloy having an alumite layer formed on the sliding surface, and a sliding surface of the first sliding component that slides on the sliding surface to provide a predetermined A combined sliding member (Patent Document 1) is known that includes a second sliding component made of polymer resin, reinforcing fibers, and solid lubricant.
また、省エネルギー化の観点から様々な産業分野において機器の小型化が求められており、これに伴って例えば、転がり軸受とハウジングの組合せ摺動部材における軸受は薄肉化される傾向にある。そして薄肉化された軸受、例えば転がり軸受などにおいて、摺動環境によっては外輪などの固定側部品がハウジングに対して回転するクリープ現象が生じる可能性がある。クリープ現象はハウジングの摩耗を進行させ、回転機器の不具合を生じさせ得る。
In addition, from the viewpoint of energy saving, there is a demand for downsizing of equipment in various industrial fields, and along with this, for example, there is a tendency for bearings in sliding members that combine rolling bearings and housings to be thinner. In thin-walled bearings such as rolling bearings, there is a possibility that a creep phenomenon may occur in which a fixed side component such as an outer ring rotates with respect to a housing depending on the sliding environment. The creep phenomenon accelerates housing wear and can cause failure of rotating equipment.
上述の従来技術のように、固体潤滑剤等を含む高分子樹脂の層を形成するためには、焼成工程が必要である。このため、昨今、対策が必要とされている地球温暖化の観点から、ライフサイクルアセスメントにおける温室効果ガスの発生量の削減という課題がある。
例えば、転がり軸受とハウジングの組合せ摺動部材などにおけるクリープ現象に伴うハウジングの摩耗の防止のために、ハウジングと接する摺動面に固体潤滑剤等を含有する高分子樹脂層を形成するには、焼成工程が必要となり、軸受の製造工程が煩雑となる上に温室効果ガスを生じさせてしまう。
また、特許文献1に示されているようにアルマイト層を形成するためには、酸性の処理液を用いる陽極酸化処理などのように比較的、煩雑な工程が必要となり、また、電力消費が増加する。 As in the prior art described above, a sintering step is required to form a layer of polymeric resin containing a solid lubricant or the like. Therefore, from the viewpoint of global warming, for which countermeasures are required these days, there is a problem of reducing the amount of greenhouse gases generated in the life cycle assessment.
For example, in order to prevent abrasion of the housing due to creep phenomenon in a sliding member combining a rolling bearing and a housing, a polymer resin layer containing a solid lubricant or the like is formed on the sliding surface in contact with the housing. A firing process is required, which complicates the manufacturing process of the bearing and produces greenhouse gases.
In addition, in order to form an alumite layer as shown inPatent Document 1, a relatively complicated process such as an anodizing treatment using an acidic treatment liquid is required, and power consumption increases. do.

Secondary Coating A baked coating containing a solid lubricant may be formed on the phosphate coating such as the manganese phosphate coating. For example, it is a fired film containing an organic binder, a curing agent, a solid lubricant, and the like. However, in order to form a sintered film containing a solid lubricant, a sintering process is required to heat the material such as the sintered film, and depending on the sintering process, carbon dioxide, which is a greenhouse gas, is also emitted. . Therefore, if only a phosphate film containing a predetermined component such as copper is provided by a simple method as described above, it is possible to improve the efficiency of the manufacturing process and reduce the generation of greenhouse gases.
