適な摺動部材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding member suitable for application to sliding surfaces of internal combustion engine piston rings, cylinder liners, air compressors, and the like.
近年、内燃機関において性能を向上させる目的で、高回

軽合金の使用、小型化等の要求から、耐摩耗性、耐焼付
性材料および低摩擦材料の必要性は大なるものがあり、
従来から多くの検討がなされている。In recent years, in order to improve the performance of internal combustion engines, there has been a demand for higher rotation speeds and higher compression, as well as the use of light alloys and miniaturization to reduce weight and improve fuel efficiency. There is a great need for low-friction materials.
Many studies have been made in the past.
かかる対策の一つとして摺動部に、金属、酸化物、炭化
物を溶射して、耐摩耗性皮膜を形成せしめることは従来
から既に知られており、その応用例も多い。As one of such countermeasures, it has been known for a long time to form a wear-resistant film on the sliding parts by spraying metal, oxide, or carbide, and there are many examples of its application.
ピストンリングに例をとって、従来の問題点を述べる。Using piston rings as an example, we will discuss conventional problems.

耗、スカッフィングの発生を生じる。Most conventional piston rings are surface-treated by applying chrome plating or molybdenum spraying to the outer circumferential surface of the iron-based base ring, but chrome-plated piston rings can withstand temperatures of 300°C or higher. When this happens, the hardness decreases, and under severe conditions, oil runs out, causing wear and scuffing.

限られている。On the other hand, molybdenum sprayed piston rings do not lose their hardness at temperatures above 300°C and have good scuffing resistance, so they are widely used in North America and Europe. It has the drawback that its adhesion to the base material and wear resistance are inferior to that of chrome plating, so its use in Japan is rare and its use is limited to special vehicles.

る。The present invention aims to reduce costs, improve wear resistance, and adhesion compared to molybdenum thermal spraying, and improve scuffing resistance and high-temperature usage limits compared to chrome plating. This eliminates the drawbacks of molybdenum thermal spraying and can be applied to various sliding surfaces, such as
The object of the present invention is to provide a sliding member that can be used as a wear-resistant and anti-seizure coating layer on many sliding surfaces such as piston rings, cylinder liners, and piston sliding surfaces.

The abrasion test was conducted while applying 30%.
結果は、実施例１と同様、クロムメッキは１０分間程度

The plasma sprayed coating of -90 to 70% Fe-high Cr alloy also produced some smoke in 10 to 20 minutes, and the chilled casting material was also slightly worn.
Ｍｏプラズマ溶射は硬さがビッカース硬さで３００〜４

待できるが、耐スカッフィング性についてはＭｏ溶射よ
り劣る。The Fe-high Cr alloy thermal spray coating has a Vickers hardness of 830.
~1000, which is about the same hardness as chrome plating, and can be expected to have wear resistance, but its scuffing resistance is inferior to Mo spraying.

保持すると、ビッカース硬さで６００前後あったものが
３５０〜４００に低下し、耐摩耗性に問題が残る。In addition, Fe-high Cr alloy showed no decrease in hardness even at high temperatures of 300 to 350°C, but
E-based alloys, such as those homogeneously mixed with carbon steel powder and plasma sprayed, exhibit almost the same properties as MO+Fe-high Cr alloys at room temperature, but when kept at high temperatures of 300 to 350°C for a long time, they exhibit Vickers hardness. The hardness of the wear resistance has decreased from around 600 to 350-400, leaving problems with wear resistance.

ス溶射法で、同時溶射する方法が特許となっているが、
２つの溶射装置が必要であること、同時溶射のため気孔
が多いことなどの欠点を持っている。In addition, as a method for maintaining hardness with Mo, there is a patented method in which Mo is thermally sprayed using a gas spraying method, and Fe-based alloy is simultaneously thermally sprayed using a plasma or gas spraying method.
It has disadvantages such as the need for two thermal spraying devices and the large number of pores due to simultaneous thermal spraying.

るなどの欠点を持っている。In addition, a method of homogeneously mixing oxides, carbides, and Mo and plasma spraying is known, but the hardness of oxides and carbides is 1ooo or more on the Vickers hardness, and the hardness of Mo is 300 to 450. There are disadvantages such as large differences in processability, difficulty in processability, and depending on the shape of the oxide or carbide, it may cause wear of the mating material.

が悪くなる。MO45 to 70%, remaining Fe-high Cr alloy 55
~30% has a Vickers hardness in the range of 450 to 820 and exhibits excellent wear resistance and seizure resistance, but M
When O is 45%, especially 30% or less, it exhibits seizure resistance that is almost the same as Fe-high Cr alloy, and when MO exceeds 70%, the hardness becomes as low as 350 to 450, resulting in poor wear resistance. becomes worse.

えられるが、この場合は、Ｆｅ−高Ｃｒ合金よりコスト
が８〜１０倍も高いこと、熱膨張係数が高く、厚く溶射
できないなどの欠点がある。As a metal, there is a Ni-based self-fluxing alloy that has the same function as the Fe-high Cr alloy, and it is also possible to mix it with MO, but in this case, the cost is 8 to 80% lower than the Fe-high Cr alloy. It has drawbacks such as being 10 times more expensive, having a higher coefficient of thermal expansion, and not being able to be sprayed thickly.
実施例１および実施例２より次のことが分かる。The following is understood from Examples 1 and 2.
クロムメッキは、硬度が高く、耐摩耗性に富み、低摩擦

も優れるが大差ではなく、摩擦係数も高い。The 10-30% MO-90-70% Fe-high Cr alloy plasma sprayed coating is superior to chrome plating in terms of seizure resistance, but not by much, and also has a high coefficient of friction.
また、耐摩耗性は普通だが、耐スヵフィング性が劣る。In addition, the wear resistance is average, but the scuffing resistance is poor.
