本発明は複合潤滑被膜に関し、特に航空機などに用いら
れる各種軸受に利用できる密着性及び潤滑性に優れた複
合潤滑被膜に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composite lubricant coating, and more particularly to a composite lubricant coating with excellent adhesion and lubricity that can be used in various bearings used in aircraft and the like.
Ｍｏ５ｚ 、 ＢＮ は層状結晶構造をもつため、せん
断力が作用すると層間で容易に剥離するという特徴をも
ち、固体潤滑剤としての機能を有している。固体潤滑剤
の特徴は通常の潤滑油が使えないような高温域や極めて
苛酷な部分などでも使用できるととである。Since Mo5z and BN have a layered crystal structure, they have the characteristic that the layers easily peel off when shear force is applied, and have a function as a solid lubricant. Solid lubricants are characterized by their ability to be used in high-temperature areas and extremely harsh areas where regular lubricants cannot be used.
特に、ＢＮ はＭＯＳ２に較べて融点も３倍程度高い（
５０００℃）ため、固体潤滑剤としての適用拡大が図ら
れている。In particular, the melting point of BN is about three times higher than that of MOS2 (
5,000°C), and its use as a solid lubricant is being expanded.

よって、被覆母材にＢＮ 被膜を形成させることによっ
て使用されている。Normally, when BN is used as a solid lubricant, it is used as a film or mixed with grease, etc., but especially when used as a film, it can be used at temperatures, pressures, and environments where grease cannot be used. ■Weight and volume can be reduced. ■No gas release. (2) Since it has advantages such as little change over time, it is used by forming a BN film on the coated base material using a vacuum deposition method such as ion blasting.

欠点があった。From the viewpoint of durability, the BN coating formed by a vacuum deposition method such as ion blating must have excellent adhesion (peeling resistance) to the coating base material. However, the conventional BN coating has a very small coefficient of thermal expansion (approximately 1710) compared to general steel materials, so it has the disadvantage that it is easily peeled off due to the generation of residual stress due to the difference in shrinkage.
本発明は上記ＢＮ 被膜の密着性（耐剥離性）の欠点を
解消した複合潤滑被膜を提供しようとするものである。The present invention aims to provide a composite lubricating coating that eliminates the drawbacks of the adhesion (peeling resistance) of the BN coating.

、６０％、８０％、１００％のものを作製した。Using tool steel (SKH55) as the coating base material, a composite lubricating coating of N1-BN as shown in FIG. 1 was prepared by a two-photoelectron beam evaporation method. In addition, in order to investigate the relationship between the mixing ratio of N1 and BN, adhesion, and lubrication performance when preparing the composite lubricant coating, the amount of BN supported was 0%, 20%, 40%
, 60%, 80%, and 100%.

されていることが解る。In addition, regarding the evaluation of these characteristics, adhesion is evaluated from the coating peeling rate by bending test, and lubricity is evaluated by measuring the coefficient of friction. As can be seen from the figure, by forming a composite coating with N1, a composite lubricating coating with excellent adhesion and lubricity is formed.
以上述べたようにイオンブレーティング等の真空蒸着法

どがあシ得るが、その何れの方法によっても差支えない
。In addition, as for the method for producing the composite lubricant coating, other than the electron beam evaporation method, ion blating method, sputtering method, etc. may be used, but any method may be used.

被膜を得ることが可能であシ、耐久性の向上が図れる。From the viewpoint of durability of solid lubricant coatings, adhesion between the coating base material and the coating film is an important point, but conventional BN coatings have the disadvantage of poor adhesion resistance and easy peeling. To solve this problem, we developed N1, which has excellent adhesion.
and BN were simultaneously coated to form a composite lubricant coating in which N1 supported BN. This makes it possible to obtain a lubricating film with excellent adhesion and improve durability.
