比較例2と同様の裏金及びニッケル49質量%、燐3質量%に加えて残部として鉄及び不可避不純物48質量%を含むアトマイズ合金粉末を用意した。裏金の一方の面のニッケル皮膜の表面にアトマイズ合金粉末を散布し、一様な厚さの未焼結のアトマイズ合金粉末層を作製した。ついで、水素・窒素混合ガス(25vol%H2−75vol%N2)の還元性雰囲気に調整した焼結炉に搬送して900℃、910℃、920℃及び930℃の温度で夫々10分間焼結した。冷却後、焼結炉から取り出したところ、焼結温度が930℃の温度で焼結した場合に限り、多孔質焼結合金層が裏金の一方の面にニッケル皮膜を介して一体的に接合されていることを確認した。複層焼結板の多孔質焼結合金層は、鉄−ニッケル合金を含むマトリックス相と該マトリックス相の内部にニッケル−燐−鉄合金を含んで発生された液相から析出されたニッケル−燐−鉄合金を含む硬質相とを備えた組織を呈しており、該マトリックス相のマイクロビッカース硬さ(MVH)は、当該マトリックス相の7か所の部位の測定値の平均値で267を示し、硬質相のマイクロビッカース硬さ(MVH)は、当該硬質相の7か所の部位の測定値の平均値で660を示した。
速度 1.3m/min
荷重(面圧) 300kgf/cm2
試験時間 20時間
相手材 機械構造用炭素鋼(S45C)
潤滑 油中(出光興産社製「ダフニースーパーマルチオイル#32(商品名)」)
図4に示すように、実施例1から実施例9並びに比較例1及び比較例3の夫々の複層焼結板から作製された一辺が30mmの方形状の軸受試験片17を試験台に固定し、相手材となる円筒体18から軸受試験片17の一方の面19に、当該面19に直交する方向Xの所定の荷重をかけながら、円筒体18を当該円筒体18の軸心20の周りで方向Yに回転させ、軸受試験片17と円筒体18との間の摩擦係数及び20時間試験後の面19の摩耗量を測定した。
