〔産業上の利用分野〕
本発明は、軸受部に用いる基本組成が銀９台などの軟質
貴金属からなる固形潤滑材に関する。DETAILED DESCRIPTION OF THE INVENTION 2. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a solid lubricant for use in a bearing portion, the basic composition of which is a soft noble metal such as silver.
本発明は、基本組成が銀−金合金からなる軟質貴金属合

ものである。The present invention has a soft noble metal alloy coating whose basic composition is a silver-gold alloy, which is firmly fixed to the shaft of a bearing or the surface of a bearing member, so that it can be used in environments such as dust-proof rooms and high temperatures and high vacuums. It has improved durability, dust resistance, and degassing resistance.

の非金属粒子を配合し、これ等を潤滑材とすることによ
って、軸受部の討入性を持たせていた。Conventionally, solid lubricants using soft precious metals have been coated with gold or gold on the bearing surface, as shown in, for example, Japanese Patent Publication No. 54-85127, Japanese Patent Publication No. 54-89943, and Japanese Patent Publication No. 54-93741. Non-metallic particles of n or s micron size are mixed into gold alloy (Au-Ni alloy) coatings or other noble metal coatings, and these are used as lubricants to make the bearing part easier to drill into. .
しかし、この様な貴金属固形潤滑材は、金または金を主

は軸受材等の表面に長期間固着できずに、徐々に展延し
、散乱してしまう。この結果、軸受部等が破損、焼付き
を生じ寿命が短かいという問題点を有する。However, such noble metal solid lubricants are made of gold or the above-mentioned alloys mainly composed of gold, or those containing α5 in the metal film.
The cost is high because it contains non-metallic particles of micron size or less. In addition, due to the high malleability and low work hardening characteristic of gold, it can withstand high loads, sliding, and forging of the bearing part, and gradually expands without sticking to the surface of the shaft or bearing material for a long time. It spreads and becomes scattered. As a result, there is a problem in that the bearing portion or the like is damaged or seizes, resulting in a short life span.
そこで本発明は、この様な問題点を解決するもので、そ

し、かつ固形潤滑材からの脱ガス、昇華等による環境汚
染防止を提供するところにある。The present invention is intended to solve these problems, and its purpose is to ensure that the bearing portion has long-term durability in special environments such as dust-proof rooms, high temperatures, and high vacuum. It also provides protection against environmental pollution due to degassing, sublimation, etc. from solid lubricants.
本発明の固形潤滑材は、軟質貴金属である銀−金合金を
使用して、その配合比は銀を主体として金の比率が３〜
４０チであることを特徴とする。The solid lubricant of the present invention uses a silver-gold alloy, which is a soft precious metal, with a blending ratio of silver as the main component and gold as the main component.
It is characterized by being 40 inches.

て非酸化性酸類で充分にクロム酸化皮膜を除去すること
がメッキの密着性を確保する上で重要である。The method of processing the solid lubricant of the present invention is a plating method, but since dry plating has a low effective utilization rate of metal of several inches, wet plating is advantageous because it can obtain an effective utilization rate of about 40 inches. In addition, in the case of wet plating, etc., if the shaft or bearing material is chrome steel or stainless steel, it is necessary to sufficiently remove the chromium oxide film with a non-oxidizing acid in the plating pretreatment to ensure the adhesion of the plating. is important.

２ｆ１類とも容易である。まず合金メッキ法については
、銀、金ともにそれぞれのシアン錯塩の配合比によって
、夜中の金の配合比を決定する。Next, there are two methods for alloying silver and gold according to the present invention: an alloy plating method or a method in which silver and gold are plated in two layers and gold is diffused. Both 2f1 types are easy. First, regarding the alloy plating method, the mixing ratio of gold during the night is determined by the mixing ratio of cyanide complex salts for both silver and gold.
つぎに、銀と金の２層メッキ法については、下地メッキ
に金メッキを使用し、銀メツキをその上から処理する。Next, regarding the silver and gold two-layer plating method, gold plating is used as the base plating, and silver plating is applied over it.

、１５００〜２００Ｃの加熱処理によって金の拡散が促
進される。この金の拡散によって、銀と金が合金化され
るが、その配合比率は、それぞれのメッキ層の厚みに比
例する。Although gold diffusion progresses gradually even if left in this state naturally, gold diffusion is promoted by heat treatment at 1500 to 200C. Through this diffusion of gold, silver and gold are alloyed, and the mixing ratio thereof is proportional to the thickness of each plating layer.
なお、金メッキ層は銀と基材の双方に拡散するため、メ

特性を持つうえ、経済的でもある。Note that the silver-gold mixing ratio is determined depending on the type of bearing, etc. FIG. 1 shows the relationship between the mixing ratio of gold and hardness during the night of the present invention. The solid line shows the hardness at the time of alloy ratio, and the dotted line shows the hardness after work hardening. When used as a solid lubricant for bearings, sliding, rolling, f! J @
'Because work hardening occurs due to the load during the J movement,
In practical terms, the hardness shown by the dotted line represents the properties of the silver-gold alloy as a solid lubricant. Pure @l has a suitable hard hole, does not spread out from the bearing part and scatters, and maintains a good condition in the initial stage, but when operated in the atmosphere, it combines with oxygen in the atmosphere and deteriorates. Next, high hardness silver oxide increases and damages the bearing. However, as the gold content increases during the night, the properties of the alloy as a whole become difficult to oxidize due to the diffused gold, and the gold ratio during the night becomes 4.
If it is kept at 0%, it will hardly be oxidized. On the other hand, if the amount of gold increases too much, the change in hardness due to oxidation will disappear, but the ductility of gold will cause the alloy to scatter from the bearing, resulting in damage to the bearing. For the above reasons, a silver-gold blending ratio of 3 to 40% gold has excellent properties as a solid lubricant and is also economical.
