Description
【発明の詳細な説明】 本発明は耐摩耗性銅合金に関するものである。[Detailed description of the invention] The present invention relates to wear-resistant copper alloys.
従来高速高荷重の下で使用される耐摩耗性銅合金として
は、高力黄銅にＳｉを添加したＭｎ５Ｓｉ＝析出物系黄
銅が知られている。しかしながら、高と苛酷な摺動条件
化では耐摩耗性等実用面で充分とはいえず更に高性能な
ものが望まれている。Conventionally, as a wear-resistant copper alloy used under high speed and high load, Mn5Si=precipitate-based brass, which is made by adding Si to high-strength brass, is known. However, under high and severe sliding conditions, wear resistance and other properties are not sufficient from a practical standpoint, and even higher performance is desired.
本発明は上記の点に鑑みて提案されたもので、高力黄銅

０５〜２．０゜Ｍｏ０、０１〜１．０％および残部Ｚｎ
よりなること、およびこの合金にｐｂｏ、ｔ〜３．０％
添加したことを特徴とする。The present invention was proposed in view of the above points, and aims to provide a copper alloy having superior wear resistance compared to high-strength brass.
~6.0, Mn 1.0, Si0, SiO,
05~2.0゜Mo0, 01~1.0% and balance Zn
and this alloy contains pbo, t~3.0%
It is characterized by the addition of
上記各構成元素を選定し、また上記割合に限定した理由
は以下の通りである。The reasons for selecting each of the above constituent elements and limiting them to the above proportions are as follows.
Ａ々はβ相形成便進元素であり、合金のＷ１機械的度を
向上させるが、添加量が６．０重量％を上回ると鋳造組
織を粗大化する傾向があり、また酸化スラグを生成しや
すく、靭性が低下する。一方添加量が０、５重量％を下
回ると強靭効果が認められない。A's are β phase forming facilitating elements and improve the W1 mechanical properties of the alloy, but if the amount added exceeds 6.0% by weight, they tend to coarsen the casting structure and also generate oxidized slag. easily, and the toughness decreases. On the other hand, if the amount added is less than 0.5% by weight, no toughening effect will be observed.
ＭｎはＡ々同様合金の機械的強度を向上させ、また耐摩
耗性を向上するＭｎ５Ｓｉ３金属間化合物を析重量％を
上回っても効果が認められない。一方添加量が１．０重
量％を下回ると上記金属間化合物の析出が極端に減少す
る。Like A, Mn improves the mechanical strength of the alloy and also improves the wear resistance. Even if the amount of Mn5Si3 intermetallic compound exceeds the amount by weight, no effect is observed. On the other hand, if the amount added is less than 1.0% by weight, precipitation of the above-mentioned intermetallic compound will be extremely reduced.
ＳｉはＭｎと上記金属間化合物を析出させるために必須
の元素であり、その添加量はＭｎとの比率から決められ
る。ただし、添加量が２．０重量％を上回ると合金を脆
化し、一方０、０５重量％を下回ると上記金属間化合物
の析出が極端に減少する。Si is an essential element for precipitating Mn and the above-mentioned intermetallic compound, and the amount of Si added is determined based on the ratio with Mn. However, if the amount added exceeds 2.0% by weight, the alloy will become brittle, while if it is less than 0.05% by weight, the precipitation of the intermetallic compound will be extremely reduced.
Ｍｏは本合金特有の金属間化合物を析出させるには必須
の元素で、Ｍｎ５Ｓｉ３化合物以外に、高硬度なＭｏ−
３ｉ系金金属化合物を析出し、これが耐摩耗性に着しい
効果を示し、１．０％以上では析出物が粗大化し、偏析
が生じ、０、０１％以下では上記効果が認められない。Mo is an essential element for precipitating intermetallic compounds unique to this alloy, and in addition to the Mn5Si3 compound, Mo-
A 3i-based gold metal compound is precipitated, which has a significant effect on wear resistance. If it is 1.0% or more, the precipitates become coarse and segregation occurs, and if it is 0.01% or less, the above effect is not observed.
Ｐｂは上記銅合金の優れた耐摩耗性を維持しながら、機
械加工性、特に被切削性を向上させることを目的とし、
添加量が３％以上では成分偏析が着しくなり強度低下が
見られ、一方添加量が０、１％以下では被切削性を向上
させる効果は認められない。The purpose of Pb is to improve machinability, especially machinability, while maintaining the excellent wear resistance of the copper alloy.
If the amount added is 3% or more, component segregation becomes severe and a decrease in strength is observed, while if the amount added is 0.1% or less, no effect of improving machinability is observed.
