（産業上の利用分野）
本発明は母材の表面に主としてプラズマ溶射によって摺
動部材用の溶射層を形成するための粉末溶射材に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a powder sprayed material for forming a sprayed layer for a sliding member on the surface of a base material mainly by plasma spraying.
（従来の技術及びその問題点）
摺動部材、例えば滑り軸受は用合金は軸受は面に潤滑油
の膜を固着させ、軸面を滑らかに摺動させる機能が要求
される。(Prior Art and its Problems) Sliding members, such as sliding bearings, are required to have the ability to adhere a film of lubricating oil to the surface of the alloy bearing surface and allow smooth sliding on the shaft surface.
この油膜が切れると軸受面と軸面とが直接接触して摩擦
を増し、摩耗が激しくなり、焼き付けを来すようになる
。When this oil film breaks, the bearing surface and shaft surface come into direct contact, increasing friction, resulting in severe wear and seizure.
軸受台金は、耐摩耗性、耐焼付は性、疲労強さ、抗圧強
さ、耐食性等が要求されるが、中でも耐摩耗性は前記の
如く焼き付けと大きな関係がある。Bearing base metals are required to have wear resistance, seizure resistance, fatigue strength, compressive strength, corrosion resistance, etc. Among them, wear resistance has a large relationship with seizure resistance as described above.
従来は軸受は合金は＾ＬＢＣ３、ＰＢＣ３等のＣｕ合金
が用いられているが、これらＣｕ合金は高価であり、軸
受は部材全体をこれらＣｕ合金で形成することは、コス
ト高を招来する。Conventionally, Cu alloys such as LBC3 and PBC3 have been used for bearings, but these Cu alloys are expensive, and forming the entire bearing member from these Cu alloys results in high costs.
又、Ｃｕ合金単体では、耐摩耗性について十分満足出来
るとは言い難く、品質の改善が求められていた。In addition, it is difficult to say that the Cu alloy itself is sufficiently satisfactory in terms of wear resistance, and there has been a demand for improvement in quality.
（問題点を解決する為の手段）
本発明は、耐摩耗性に優れた金属粉末にて母材に溶射層
を形成することによってコストを低減でき、且つ耐摩耗
性を向上出来る摺動部材用溶射材を明らかにするもので
ある。(Means for Solving the Problems) The present invention provides a material for sliding members that can reduce costs and improve wear resistance by forming a sprayed layer on a base material using metal powder with excellent wear resistance. This clarifies the thermal spray material.
本発明の溶射材は、Ｃｒ、Ｃ２とＮｉ基基金金粉末はＣ
ｒ５Ｃ２とＣｏ基き金粉末を混合してｖｉ焼結した複合
粉末とＣｕ合金粉末とを混合したものである。The thermal spray material of the present invention has Cr, C2 and Ni based gold powder.
This is a mixture of composite powder obtained by vi-sintering a mixture of r5C2 and Co-based gold powder and Cu alloy powder.
（作用及び効果）

いても、母材の表面に溶射層を形成して、摺動部材とし
ての特性を付与でき、又、母材の選択によっては、従来
のＣｕ合金では得られない強じんな摺動部材が得られる
。(Function and Effect) Even if the base material is inferior in the properties required for a sliding member, a sprayed layer can be formed on the surface of the base material to impart the properties as a sliding member. Depending on the selection of materials, a strong sliding member that cannot be obtained with conventional Cu alloys can be obtained.
溶射層にＣｕ合金が含まれるため、耐焼付性は良好で、
Ｎｉ基合金粉末とＣｒｔＣ２又はＣｏ基合金粉末とＣｒ
３Ｃ２との複合金属によって耐摩耗性を向上できる。Since the thermal spray layer contains Cu alloy, it has good seizure resistance.
Ni-based alloy powder and CrtC2 or Co-based alloy powder and Cr
Wear resistance can be improved by composite metal with 3C2.
（実施例） 以下の説明で％表示及び混合比率は総て重量％による。(Example) In the following explanation, all percentages and mixing ratios are based on weight percentages.

ラフに表したものである。Figure 1 shows that the proportion of Cu alloy powder in the thermal spray material is 30%.
%, and by changing the mixing ratio of Cr-C2 in the remaining 70% and Ni-based alloy that is the metal matrix, a sprayed layer was formed on the base material, and the specific wear amount of this sprayed layer and ^LBC3 alone was graphed. It is expressed.

プラズマ溶射においては、溶射材の送給性が溶射の成否
を決定する重要な要因であって、丸味のある直径５０μ
ｍ程度の微細な粒体は極めて送給性が良い。In plasma spraying, the feedability of the spraying material is an important factor that determines the success or failure of the spraying process.
Fine particles on the order of m in size have extremely good feedability.
又、仮焼結する理由はＣｒ３Ｃ２と金属マトリックスと
のな染みを良くし、溶射層にＣｒ、Ｃ２を均一に分布さ
せるためである。Further, the reason for pre-sintering is to improve the staining between Cr3C2 and the metal matrix and to uniformly distribute Cr and C2 in the sprayed layer.

Apply a load of 2 kgf to press the thermal spray N (2).
溶射方法は、プラズマ溶射（使用機種メチコアＭＰ）、
溶射条件は、電流８００Ａ、電圧５２Ｖである。The spraying method is plasma spraying (model used: Meticore MP),
The thermal spraying conditions were a current of 800 A and a voltage of 52 V.

本発明では、後記の理由により、比摩耗量の目標を０．
３５以下とした。In the present invention, the target specific wear amount is set to 0.0 for the reasons described later.
It was set to 35 or less.
Ｃｒ３Ｃ２の割合が５０％以下であると、高価な金属マ
トリックスであるハステロイＣの混合割合が増え、コス
ト高を招来し、経済効果が小さい。If the proportion of Cr3C2 is less than 50%, the proportion of Hastelloy C, which is an expensive metal matrix, increases, resulting in high costs and small economic effects.
Ｃｒ３Ｃ２の割合が９０％を越えると、他の金属粉末と
の密着性が悪く、溶射出来ないことが判った。It has been found that when the proportion of Cr3C2 exceeds 90%, adhesion with other metal powders is poor and thermal spraying cannot be performed.
従って、本発明では、Ｃｒ３Ｃ２の割合が５０％以上で
、溶射可能な上限である９０％以下の範囲に限定した。Therefore, in the present invention, the proportion of Cr3C2 is limited to a range of 50% or more and 90% or less, which is the upper limit of thermal spraying.
Ｃｒ、Ｃ２の割合が５０％以上、９０％以下の範囲での
比摩耗量が０．３５であった。The specific wear amount was 0.35 when the proportions of Cr and C2 were in the range of 50% or more and 90% or less.

試験方法は前記と同様である。The test method is the same as above.
溶射材中のＣｕ合金粉末１０〜５０％の範囲であれば、
比摩耗量が０．３５の範囲に収まった。If the Cu alloy powder in the thermal spray material is in the range of 10 to 50%,
The specific wear amount fell within the range of 0.35.
Ｃｕ合金粉末の割合が１０％以下又は５０％を越えると
比摩耗量が０．３５以上になり目標の値に達しない。If the proportion of Cu alloy powder is less than 10% or more than 50%, the specific wear amount will be more than 0.35 and will not reach the target value.
