〔産業上の利用分野〕
鋼に銅合金を融着接合した製品はこれまで、シリンダ一
部品、すべり合金軸受などとして使用されている。[Detailed Description of the Invention] [Industrial Field of Application] Products made by fusion bonding copper alloy to steel have been used as parts of cylinders, sliding alloy bearings, and the like.
［従来の技術］
鋼に銅合金を融着接合する技術は、すこぶる困姉なもの
である。今日、鋼を硼砂などで被覆し、これを加熱（約
１１００°Ｃ）、銅合金を鋳造しているが、多くの技術
と経験が必要であった。[Prior Art] The technology of fusion bonding a copper alloy to steel is extremely difficult. Today, steel is coated with borax, heated (approximately 1100°C), and copper alloys are cast, but this requires a great deal of skill and experience.
［発明が解決しようとする課題〕 鋼に対して簡単に銅合金を融着接合する方法。[Problem to be solved by the invention] A simple method for fusion bonding copper alloy to steel.
［課題を解決するための手段〕
鋼に対して金を薄く被覆（溶射、蒸着、あるいはメツキ
）し、これを遠心鋳造機あるいは鋳型に設置し、銅合金
を鋳造する。金は鋼の酸化を防ぎ、かつ銅合金と容易に
融合するので両者は簡単に溶融接合することが判明した
。[Means for solving the problem] Steel is coated with a thin layer of gold (by thermal spraying, vapor deposition, or plating), and this is placed in a centrifugal casting machine or mold to cast a copper alloy. It has been found that gold prevents oxidation of steel and easily fuses with copper alloys, making it easy to melt and join the two.
〔作用］
鋼に銅合金を融着接合する際のポイントは高温下（約ｔ
＋ｏｏ’Ｃ）において鋼を酸化させないことにある。こ
のため、これまで硼砂などの溶剤で鋼の酸化を防ぎ、こ
れと幻司合金の浴湯とを置換させ、融着接合を行なって
いるが不良品が多く発生した。[Function] The key point when fusion bonding copper alloy to steel is to bond it at high temperature (approximately t
The purpose is not to oxidize the steel at +oo'C). For this reason, up until now, oxidation of the steel has been prevented using a solvent such as borax, and this has been substituted with bath water for the Genji alloy to perform fusion bonding, but this has resulted in many defective products.
本発明の鋼に金を被覆したものは高温で酸化しないので
銅合金の融着接合が非常に容易になった。Since the steel of the present invention coated with gold does not oxidize at high temperatures, fusion bonding of copper alloys has become very easy.
［実施例〕
外径８３４ｍｍ、内径８０２ｍｍ、 １］２８２ｍｍの
鋼（ＳＳ４１および５Ｆ５０）の裏金に金を０２μｍメ
ツキし、これを遠心鋳造機に設置した。次に同機を始動
し、高周波で約１１００°０まで裏金を加熱後、銅合金
（銅・鉛合金；ＫＪ３）を鋳造し、水冷凝固せしめた。[Example] An outer diameter of 834 mm, an inner diameter of 802 mm, 1] A back metal of 282 mm steel (SS41 and 5F50) was plated with gold to a thickness of 02 μm, and this was placed in a centrifugal casting machine. Next, the machine was started, and after heating the back metal to approximately 1100°0 with high frequency, a copper alloy (copper-lead alloy; KJ3) was cast and solidified by water cooling.
これを機械加工し、染色浸透探傷剤で密着性を検査した
が何れも欠陥は無かった。次に本体よりチャルマー密着
試験片を採取し、密着力を測定した。次表に試験結果を
示す。This was machined and the adhesion was inspected using a dye penetrant inspection agent, but no defects were found. Next, a Chalmers adhesion test piece was taken from the main body and the adhesion force was measured. The test results are shown in the table below.
即ち、５Ｓ４１に対するＫＪ３の密着力は１４６に帥１
．５Ｆ５０に対するＫＪ３の密着力は１５２に９７ｍｍ
２であった。この値は銅合金（ＫＪ３）の強度とはゾ同
一であり、密着性の優れていることが判明した。In other words, the adhesion force of KJ3 to 5S41 is 146 times 1
．． The adhesion force of KJ3 to 5F50 is 97mm to 152
It was 2. This value was the same as the strength of the copper alloy (KJ3), and it was found that the adhesiveness was excellent.
本発明の鋼に金を被覆し、銅合金を融着接合する方法は
非常に簡便で、かつ安定した高品位の製品を得ることが
できるので斯界に大いに貢献できるものと確信する。We believe that the method of coating gold on steel and fusion-bonding copper alloy according to the present invention is very simple and can produce a stable, high-quality product, so it will make a great contribution to this field.
