Description
式(4)において、Xは合金中の実際のCu含有率(質量%)、Yは合金中の実際のZn含有率(質量%)、qはCu、Zn以外の元素含有率(質量%)、tはCu、Zn以外の元素の亜鉛当量係数である。そして、各元素の亜鉛当量係数は、Zn=1、Si=10、Al=6、Sn=2、Pb=1、Fe=0.9、Mn=0.5、Ni=−1.3である。なお、Coの亜鉛当量係数は未だ明確に規定されていないが、本明細書にあたっては0.5として計算する。
・相手材 SCM415 浸炭焼入 HRC56〜59(図12)
・試験速度 0.055、0.101、0.310、0.512 m/s 各3回
・荷重 初期荷重4.5N 最終荷重67N
・試験距離 200m
表面積の大きい面が試験面となり、試験片を固定し、相手材を直角に当て回転させる。荷重は連続的に増加し試験距離200m到達時67Nである。評価は試験片の試験前、試験後の重量変化より比摩耗量を算出し、比摩耗量が大きいほど耐摩耗性が悪いと評価した。
・相手材 SCM415 浸炭焼入 HRC56〜59(図14)
・試験速度 300rpm
・試験荷重 30kgf/s
・油種 シェル ターボオイル T32
試験材を相手材で挟み相手材側から連続的に荷重を増加しピンを回転させた。評価は焼付が生じた段階までに供試材に与えた仕事量(kgf・s)を測定しファビリー値とした。ファビリー値が小さいほど、耐焼付性が悪いと評価した。
Claims (1)
- 質量比で、Zn:10〜40%、Al:2〜9%、Fe:0.4〜3.5%、Ni:0.5〜4.0%、Co:0.3〜2.0%、Mn:1.0〜5.0%、Si:0.3〜3.5%を含有し、残余がCu及び不可避不純物から成り、α相+β相、α相+β相+γ相若しくはβ相の少なくとも1つにAl−Fe−Mn−Si−Ni−Co系金属間化合物が分散した組織を有し、Fe、Mn,Co及びSiの質量比が下式(1)を満たし、且つ、各元素の質量比から下式(2)によって得られた値を下式(3)に代入した際、下式(3)を満たすことを特徴とする耐摩耗性銅合金。
ここで、左辺AXは、右辺のXにCu、Sn、Pb、Zn、Al若しくはNiのいずれかの含有量を代入した際の値であり、右辺のXに含有量を代入した元素を添え字としてACu、ASn、APb、AZn、AAl若しくはANiと表す。
