Description
本発明は、例えば、慣らし運転層及び摩耗保護層の両方として機能する適合性コーティングを有する、燃焼エンジン中のピストンリングなどの滑り部品、並びにその製造方法に関する。 The present invention relates to a sliding component, such as a piston ring in a combustion engine, for example, having a conformal coating that functions as both a break-in and wear protection layer, and a method for manufacturing the same.
ピストンリングは、エンジンの全運転段階において適切な機能を保証し、かつエンジンの長い耐用年数を確保するために、シリンダー壁に対する運転面の上に摩耗保護層を備えている。運転面コーティングは、その耐用年数の経過に対して様々な要求を満たさなければならない。 The piston ring is provided with a wear protection layer on the operating surface against the cylinder wall in order to ensure proper functioning at all operating stages of the engine and to ensure a long service life of the engine. Operating surface coatings must meet various requirements over the course of their useful life.
新しいエンジンの慣らし運転中、そのコーティングは、それを破損したり、二度目の破損を起こしたりすることなく、微視的かつ巨視的にその面形状をその反対面の条件に適合させることができるべきである。慣らし運転段階が終わった後、摩耗及び焼き付きに対する高耐性などの性質によって、反対面の摩耗が低く記録され、そして低摩擦弁が重要になる。これは、耐用年数が増加するほどに、様々な機能が必要になることを意味する。 During the running-in of a new engine, the coating can adapt its surface shape to the conditions of its opposite surface microscopically and macroscopically without damaging it or causing a second failure Should. After the break-in phase, due to properties such as wear and high resistance to seizure, wear on the opposite surface is recorded low and low friction valves become important. This means that various functions are required as the service life increases.
実際には、これらの要求は、摩耗保護層に加えて塗布され、均質層又は傾斜層（それらの性質は、層の厚さ全体に亘って次第に変わる）のいずれかとして設計されることができる慣らし運転層によって満たされている。摩耗保護及び慣らし運転層は、様々なプロセスに適用され、製造コストをさらに増加させるであろう。別の欠点は、何らかの後処理作業が運転面上で行なわれる必要があるならば、既に塗布された慣らし運転層の一部分を再び除去しなければならないことであり、それ故に、慣らし運転層の一部分は、もはや慣らし運転作業に適していない。 In practice, these requirements are applied in addition to the wear protection layer and can be designed as either a homogeneous layer or a graded layer (the properties of which vary gradually throughout the thickness of the layer). Satisfied by the running-in class. Wear protection and break-in layers will be applied to various processes and will further increase manufacturing costs. Another disadvantage is that if any after-treatment operation needs to be performed on the operating surface, a part of the already applied break-in layer must be removed again, and therefore a part of the break-in layer. Is no longer suitable for break-in operation.
したがって、本発明の課題は、これらの欠点をなくし、均質コーティングとして塗布されることができ、かつ慣らし運転層及び摩耗保護層の両方として機能できるコーティングを提供することである。この滑り部品の製造方法も提案される。 The object of the present invention is therefore to eliminate these drawbacks and to provide a coating which can be applied as a homogeneous coating and which can function both as a break-in layer and as a wear protection layer. A method for manufacturing the sliding component is also proposed.
本発明の第一の態様によって、Ｔｉ、Ｃｏ、Ｃｒ、Ｚｒ又はＢｅから成る群から選択される少なくとも１つの添加物を有する銅系合金から形成された運転面コーティングを特徴とする、少なくとも１つの運転面を含む、燃焼エンジンのための滑り部品が提供される。 According to a first aspect of the present invention, at least one operating surface coating formed from a copper-based alloy having at least one additive selected from the group consisting of Ti, Co, Cr, Zr or Be A sliding component for a combustion engine is provided, including an operating surface.
この滑り部品は適合性コーティングを備えている。この適合性とは、そのコーティングが最初に比較的低い硬さを有することを意味する。この状態では、それは、例えば、新しいエンジンの慣らし運転段階中に燃焼エンジン内のピストンリング上の、慣らし運転層として機能する。ピストンリングとシリンダーの間の比較的少量の凹凸は、慣らし運転層の適合により相殺される。つまり、慣らし運転層は、シリンダー壁を破損することなく、それ自体をシリンダー壁の構造に適合させる。このようにして、良好な封止体が、ピストンリングとシリンダー壁の間に付けられる。 This sliding part is provided with a compatible coating. This compatibility means that the coating initially has a relatively low hardness. In this state, it functions as a break-in layer, for example on a piston ring in the combustion engine during the break-in phase of the new engine. A relatively small amount of unevenness between the piston ring and the cylinder is offset by the adaptation of the running-in layer. In other words, the break-in layer adapts itself to the structure of the cylinder wall without damaging the cylinder wall. In this way, a good seal is applied between the piston ring and the cylinder wall.
エンジンの耐用年数の後期では、コーティングは、高温が効くので、析出硬化を受ける。そのコーティングの硬さは増加するので、慣らし運転プロセスが終わる時まで、それは摩耗保護層として機能している。本発明によるコーティングの適合性のために、慣らし運転性から摩耗保護性への遷移は温度駆動型である。したがって、エンジン負荷、及びそのコーティングの結合温度が、慣らし運転層から摩耗保護層への遷移を制御する。それ故に、エンジン負荷が高くなるほど、耐摩耗性層の形成が速く進み、その後、その耐摩耗性層は、エンジンの耐用年数の残りの期間に亘ってその性質を保持する。 Later in the service life of the engine, the coating is subject to precipitation hardening because of the high temperatures. As the hardness of the coating increases, it functions as a wear protection layer until the end of the break-in process. Due to the suitability of the coating according to the invention, the transition from run-in to wear protection is temperature driven. Therefore, the engine load and the bonding temperature of the coating control the transition from the break-in layer to the wear protection layer. Therefore, the higher the engine load, the faster the wear-resistant layer forms, after which the wear-resistant layer retains its properties for the remainder of the engine's useful life.

本発明の第三の態様によれば、燃焼エンジン内の滑り部品の運転面のためのコーティングとしての、Ｔｉ、Ｃｏ、Ｃｒ、Ｚｒ又はＢｅから成る群から選択される少なくとも１つの添加物を含む銅系合金の使用が提供される。前記合金は、０．１〜４質量％のベリリウム及び０．１〜０．８質量％のチタン、好ましくは１〜３質量％のベリリウム及び０．２〜０．６質量％のチタン、最も好ましくは約２質量％のベリリウム及び約０．４質量％のチタンを含む。 According to a third aspect of the invention, it comprises at least one additive selected from the group consisting of Ti, Co, Cr, Zr or Be as a coating for the operating surface of a sliding component in a combustion engine. Use of a copper-based alloy is provided. The alloy is 0.1 to 4 wt% beryllium and 0.1 to 0.8 wt% titanium, preferably 1 to 3 wt% beryllium and 0.2 to 0.6 wt% titanium, most preferably Contains about 2% by weight beryllium and about 0.4% by weight titanium.
本発明は、コーティングが均質的に塗布されることを可能にするので、例えば、ピストンリングは、より速く、かつより安く製造されることができる。したがって、個別の摩耗保護層及び慣らし運転層を有するコーティング（それは、より遅く、かつより高価であろう）を回避することができる。また、本発明による滑り部品は、個別の慣らし運転層を除去する（その後、その慣らし運転層は、もはや慣らし運転段階に適していないであろう）必要なしに、容易に再加工されることができる。 For example, piston rings can be made faster and cheaper because the present invention allows the coating to be applied homogeneously. Thus, coatings with separate wear protection layers and break-in layers (which would be slower and more expensive) can be avoided. Also, the sliding component according to the present invention can be easily reworked without the need to remove a separate running-in layer (then the running-in layer will no longer be suitable for the running-in phase). it can.
本発明によるピストンリングは、１つの均質コーティング（それは、その元の条件では、慣らし運転層の性質を有する）のみを有するので、コーティングの残りの厚さが十分に残ったままならば、再加工が必要になるとしても、その慣らし運転性は失われない。そのコーティングは、それがエンジン内で働き始めるまで、その摩耗保護性を獲得しない。 Since the piston ring according to the present invention has only one homogeneous coating (which in its original conditions has the properties of a break-in layer), if the remaining thickness of the coating remains sufficiently reworked However, the running-in performance will not be lost. The coating does not acquire its wear protection until it begins to work in the engine.
従来のピストンリングと比較したときの本発明によるピストンリングのさらなる利点は、コーティングが慣らし運転段階の後でも硬さについて基本的に均質のままであることにある。一方で、従来のピストンリングでは、微量の慣らし運転層が、摩耗保護層の露出領域とともに特定の領域に残り、そしてこれらの領域は、必然的に異なる硬さを有する。慣らし運転層の残りを有する領域は比較的柔軟であるが、摩耗保護層が露出している領域は比較的硬い。 A further advantage of the piston ring according to the invention when compared to conventional piston rings is that the coating remains essentially homogeneous in hardness even after the break-in phase. On the other hand, in conventional piston rings, a small amount of the running-in layer remains in certain areas along with the exposed areas of the wear protection layer, and these areas necessarily have different hardnesses. The area with the rest of the break-in layer is relatively soft, but the area where the wear protection layer is exposed is relatively hard.
硬さが本発明におけるコーティング全体に適合しているので、そのコーティングの硬さは、慣らし運転段階の後でも基本的に均一なままである。従来のピストンリングに起こるような硬さの減少した領域が残っていないので、これは摩耗保護を強化する。 Since the hardness is compatible with the entire coating in the present invention, the hardness of the coating remains essentially uniform after the break-in phase. This enhances wear protection because there is no remaining reduced area as occurs in conventional piston rings.
また、固有の圧縮張力が本発明によるピストンリング内に形成され、これらの張力は、ひびの形成及び伝播に対するさらなる耐性を提供することが発見された。 It has also been discovered that inherent compressive tensions are formed within the piston ring according to the present invention, and these tensions provide additional resistance to crack formation and propagation.
合金系が形成された後に、最初に合金系は室温で熱力学的不平衡の状態である。例えば、熱の形態のエネルギーがそれらに掛かるならば、個別の相が堆積し、その材料を硬化させるために機能することができ、かつ特定の状況下で耐摩耗性を増加させることができる。本発明によれば、適切な方法により、運転面コーティングとしてそのような合金をエンジン内のピストンリング又は他の滑り部品に塗布することが提案される。熱的に未処理の条件では、そのようにして形成されたコーティングは、柔軟な慣らし運転層の機能を果たす。 After the alloy system is formed, initially the alloy system is in a thermodynamic unbalanced state at room temperature. For example, if energy in the form of heat is applied to them, individual phases can be deposited, function to cure the material, and increase wear resistance under certain circumstances. In accordance with the present invention, it is proposed to apply such alloys to piston rings or other sliding parts in the engine as a driving surface coating by a suitable method. In thermally untreated conditions, the coating thus formed serves as a flexible running-in layer.
コーティングの析出硬化が、運転中のエンジン及びそれによる部品の加熱により燃焼室内に発生した熱によって同時に開始する。このプロセスは温度駆動型であるから、コーティングの硬化は、エンジン負荷が増加しているときにはより速く進むであろう。つまり、エンジン自体の負荷条件は、慣らし運転層から耐摩耗性層への遷移を制御し、その後に、耐摩耗性層は、エンジンの耐用年数の残りの期間に亘ってその耐摩耗性を保持する。 Precipitation hardening of the coating is initiated simultaneously by the heat generated in the combustion chamber due to the heating of the running engine and the parts thereby. Since this process is temperature driven, the curing of the coating will proceed faster when the engine load is increasing. That is, the load conditions of the engine itself control the transition from the running-in layer to the wear-resistant layer, after which the wear-resistant layer retains its wear resistance for the remainder of the engine's useful life. To do.
機械的性質を向上させるために、鉄、アルミニウム、銅、及び冷却又は加熱処理と併用した析出硬化により素地の性質を変えることができる他の金属を主成分とする系のために極めて広い範囲の元素がある。とりわけ、Ｃｕ、Ｃｏ、Ｍｇ、Ｓｉ、Ｍｎ又はＺｎの添加物を有する、アルミニウムを主成分とする合金の種類が、加熱処理の結果としてその耐性及び硬さを増加させる能力で知られている。また、Ｔｉ、Ｃｏ、Ｃｒ、Ｚｒ又はＢｅの添加物を有する銅系合金もこれらの要求を満たす。 An extremely wide range for systems based on iron, aluminum, copper and other metals whose main properties can be changed by precipitation hardening in combination with cooling or heat treatment to improve mechanical properties There are elements. In particular, alloy types based on aluminum with additives of Cu, Co, Mg, Si, Mn or Zn are known for their ability to increase their resistance and hardness as a result of heat treatment. A copper-based alloy having an additive of Ti, Co, Cr, Zr or Be also satisfies these requirements.
実施形態：
溶射プロセスを用いて、約２質量％のベリリウム及び０．４％のチタンを含むＣｕＢｅＴｉ合金を堆積させ、運転面コーティングをピストンリングに塗布した。コーティング後の層の硬さは、約３１０ ＨＶＯ．３であった。この状態では、コーティングは慣らし運転層として機能する。一方で、エンジンの外の摩耗試験（３００℃で０．５時間）前に取り出された試料は、約４００ ＨＶＯ．３の硬さを示した。この条件では、コーティングは摩耗保護層のように機能する。
Embodiment:
A thermal spray process was used to deposit a CuBeTi alloy containing about 2% by weight beryllium and 0.4% titanium and a working surface coating was applied to the piston ring. The hardness of the layer after coating is about 310 HVO. 3. In this state, the coating functions as a break-in layer. On the other hand, the sample taken out before the wear test outside the engine (0.5 hours at 300 ° C.) is about 400 HVO. A hardness of 3 was shown. Under this condition, the coating functions like a wear protection layer.
銅を主成分とする合金を硬化させた析出試験では、固有の圧縮張力が、層に形成され、起こり得るひび形成及びひび伝播に対するさらなる耐性を提供することについて、さらなる利点が観察された。本発明の実施態様の一部を下記項目［１］〜［１２］に記載する。
