材質により向上させることができる。The cylinder liner is a diesel engine component that is important for protection from lightning in terms of function and durability.In particular, the cylinder liner is subjected to a high heat load and has a secret function along with the piston ring, which slides back and forth through high-temperature, high-pressure gas. is fulfilled. Cast iron is generally used as a material for such cylinder liners because cast iron has extremely high wear resistance. On the other hand, if cylinder liner wear is classified by its causes, there are abrasive wear due to foreign objects, scuffing wear where the worn surface melts and flows due to poor S cleaning, etc. Wear resistance against these types of wear can be improved by the material used. .
そのため、シリンダライナには高りん鋳鉄や、いわゆる
Ｐの共晶物を多量に発生させる材料や、更には、Ｐの添
加を抑えて、Ｖ、Ｂ、Ｔｉなどを添加して特殊ステダイ
トを分布させる材料など、多数の耐摩耗性向上の材料が
提案され、実施されている。For this reason, the cylinder liner is made of high-phosphorus cast iron or a material that generates a large amount of so-called P eutectic, or even suppresses the addition of P and adds V, B, Ti, etc. to distribute special steadite. A number of wear-resistance-enhancing materials have been proposed and implemented, such as materials.
一方、一般的には、例えば、前記特殊ステダイトを分布

されるという技術も知られている。On the other hand, generally, for example, as a type of method for distributing the special steadite, a technique is also known in which plate-shaped carbides, that is, plate-shaped steadite, are generated by adding Cr, Si, and P. .

ライナとしては未だ確立されておらず、安定して大量生
産する迄には至らない。However, cylinder liners made from such special steadite, with additions such as ■, B, and Ti, are widely used because they have excellent wear resistance under conditions where corrosion occurs due to heavy oil combustion waste. However, the material costs are high, and the general technology of adding Cr, 5i-P, etc. to produce plate-like carbides has not yet been established for cylinder liners, and it cannot be used stably and in large quantities. It has not reached the stage of production.
そこで本発明は、これらの問題点を解決して、安価で、

処しようとするものである。Therefore, the present invention solves these problems and is inexpensive.
The aim is to provide a cylinder liner that produces plate-shaped steadite that can be stably produced.Especially in the current situation where the recent rise in the price of fossil fuels has forced the use of low-quality fuel, abrasive wear can be avoided. It is an attempt to deal with this.
先ず、本発明の創作過程について逮ぺれば、本発明を完
成するための困難性の一つは、板状ステダイト生成に影
響を与える問題点ないし要因の解明作業であった。すな
わち、その概要をいえば、次のとおりである。先ず、本
発明の安価なＣｒ、Ｓｉ 、Ｐなどを選んだ、そして全
ステダイト面積（−ステダイト＋板状セメンダイト）に
対しては、Ｐの影響が大きく、次いで、Ｃｒとなってい
る。First, regarding the creation process of the present invention, one of the difficulties in completing the present invention was the task of elucidating the problems or factors that affect the formation of plate-like steadite. That is, the outline is as follows. First, inexpensive Cr, Si, P, etc. of the present invention were selected, and on the total steadite area (-steadite + plate-like cementite), P had a large influence, followed by Cr.
その理由は、ステダイトがＰの化合物であるＦｅＩＰに
よって成立しているとの裏付けであり、Ｐの増加により
、ステダイトの表面も増加することが判明した。一方、
Ｃｒは白銑化元素であり、板状セメンタイトの生成に大
きく関与するのであるが、殊に、板状ステダイトの白色
部はＣｒ等の白銑化元素によって晶出したセメンタイト
であることが明確になった。The reason for this is evidence that steadite is made up of FeIP, which is a P compound, and it has been found that as P increases, the surface of steadite also increases. on the other hand,
Cr is a white-pigmenting element and is greatly involved in the formation of plate-like cementite. In particular, it is clear that the white part of plate-shaped steadite is cementite crystallized by white-pigmenting elements such as Cr. became.
次に、板状セメンタイト部面積に及ぼす要因に対しては
、Ｃｒの影響が特に大きく、次にＳｉの影響があること
が判明した。これは板状セメンタイトがＣｒなどの白銑
化元素によって生成される炭化物であることを明確につ
きとめて判明した。Next, it was found that Cr had a particularly large influence on the area of the plate-like cementite portion, followed by Si. This was made clear by clearly identifying that plate-like cementite is a carbide produced by a white ironing element such as Cr.
したがって、ＣｒはＢやＶの特殊元素と同じ効果を備え

要はなく、１．３〜１．８％が適当であることをつきと
めたのである。Therefore, it was confirmed that Cr has the same effect as special elements such as B and V. In addition, in the case of Cr,
It was also discovered that plate-like cementite crystallizes stably when the magnetic field contains 0.5% or more. Next, Si
It has been clarified that Si has a negative effect, and this is because Si is a ferrite element and has the effect of inhibiting cementite formation. However, since the influence of Si is slightly smaller than that of Cr, it was found that there is no need to make the amount so small, and that 1.3 to 1.8% is appropriate.
更に、別の観点である板状化率に及ぼす原因につき検討

が判明した。Furthermore, we examined the cause of plateletization rate from another point of view, and found that plateletization rate refers to the proportion of platelet cementite in the total steadite, which includes Cr and S.
It was found that the direct factor of i appears as an effect. Furthermore, since the comparison was made with the amount of steadite, it was found that the effect of P was also indirectly observed. - Further, when examining the hardness of plate cementite and steadite, it was found that the three elements of Cr, Si, and P and the wall thickness have an effect. In particular, it has been found that unless the wall thickness is to a certain extent, the time required for eutectic solidification is short and the concentration of Cr etc. is difficult to occur. Therefore, it has been found that the cylinder liner is suitable for a cylinder liner having a bore of 15f)sn or larger.
そして、Ｐについては、Ｐの量が少ないとステダイトの
量が減少し、板状セメンタイトの周囲をとりかこむ硬い
ステダイトの壁が少ないため、硬度が低下することも判
明した。Regarding P, it was also found that when the amount of P is small, the amount of steadite decreases, and there are fewer hard walls of steadite surrounding the plate-like cementite, resulting in a decrease in hardness.
以上のごとく、本発明者は試行ｖＪ誤の結果、板状ステ

のごとき本発明を完成したのである。As described above, as a result of the trial vJ error, the present inventors have elucidated each M factor that influences the formation of plate-like steadite, and as a result, the present invention has been completed as follows.

%, Si in the range of 1.3 to 1.8% to form a plate-shaped steadite, and furthermore, 4tx of Cu-Ca was added to the invention. This invention relates to a cylinodar liner for diesel engines in which plate-shaped steadite is formed.
本発明の構成を更に詳述すれば、Ｃｒは板状ステダイト

で、これにより板状ステダイトの安定晶出を図ることが
できる。そして、０．３〜０．９％範囲以下では板状ス
テダイトが生成できず、耐摩耗性が劣化し、これ以上で
あれば、のである。To explain the structure of the present invention in more detail, Cr has the greatest effect on the formation of plate-shaped steadite, and as mentioned above, the white part of plate-shaped steadite is cementite crystallized by white ironing elements such as Cr. From what we have discovered, 0.7% is optimal, and with this, stable crystallization of plate-like steadite can be achieved. If the content is below the range of 0.3 to 0.9%, plate-like steadite cannot be produced and the wear resistance deteriorates, and if it is above this range, the problem is.
Ｐは前記のごとく、板状ステダイト生成には直接の効果
はないが、ステダイト生成の基本元素であり、かつ、耐
摩耗性を向上させるため、一定量（最適０．４５％）の
Ｐが必要であり、したがって、０．３〜０．６％にする
ことが望ましく、これ以下であれば、フェライトが生成
できず、耐摩耗性が劣化するし、これ以上であれば、脆
弱化する。As mentioned above, P has no direct effect on plate-like steadite formation, but it is a basic element for steadite formation, and a certain amount (optimally 0.45%) is required to improve wear resistance. Therefore, it is desirable to set the content to 0.3 to 0.6%; if it is less than this, ferrite cannot be produced and wear resistance deteriorates, and if it is more than this, it becomes brittle.
Ｓｌは前記のごとく、板抜ステダイト生成の阻害元素と

鋳造性が悪化し、表面がチル化し易く、これ以上では板
状セメンタイトが育成しなくなる。つまり、靭性と硬さ
のバランスを図ることができる。As mentioned above, it has been found that Sl has the effect of inhibiting the formation of blank steadite, but in order to ensure castability and mechanical properties, a quantitative amount (optimally 1.6%) is necessary. The content should be in the range of 1.3 to 1.8%, and if it is less than this, the castability will deteriorate and the surface will be likely to be chilled, and if it is more than this, plate-like cementite will not grow. In other words, it is possible to achieve a balance between toughness and hardness.

ａ接種添加は０．８〜１．２％がよいことが判明した。Next, the effect of adding Cu-Ca appeared in the micro-hardness, macro-hardness, and tensile strength of the pearlite part. A fairly remarkable effect appears on the microhardness of the pearlite portion, and this is due to the densification effect of the pearlite due to Cu. Moreover, when it comes to macro hardness, the young fruits are reduced, and this is due to the production of large quantities of plate-like steadite, when P content is more than 0.5%, and when the inoculation effect of Cu-Ca is saturated. It was determined that this was due to factors such as: Therefore, in order to improve the wear resistance by making the eutectic cells finer, and also to improve the acid corrosion wear resistance due to Cu, C11・C
It was found that 0.8 to 1.2% of the a inoculum is suitable.
かかる場合、海水直冷ライナに好適である。In such a case, it is suitable for a seawater directly cooled liner.

It has been found that it is sufficient to add only u, and that a range of 0.7 to 1.1% of Cu is good.

The mating material was a normal piston ring material which is a Cr-plated high phosphorus casting, and as a result of testing these, as seen in Table 2, the present inventions -1, Sou2, Nu3 and Arashi9. The results were good, and all of them were made by crystallizing hard plate-like steadite, and in particular, those whose matrix was reinforced with Cu/Ca showed excellent wear resistance. Conventional m5
(B yarn) is inferior to the Cr-based plate-shaped steadite material of the present invention, and the special steadite material of Ih4 (V series) is 1lh.
It is equivalent to 5, but this is because V has a stronger M partner with C. For this reason, ■ alone tends to crystallize V carbide. However, Fe in cementite is C
r is more easily substituted, and Cr is more likely to enter cementite. As a result, Cr
