まず、原料として、銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)のみを用意した。
上記銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)に代えて、銅−ニッケル−ケイ素−バナジウム−クロム合金粉末(組成:Cu−14Ni−3Si−2V−2.2Cr−1.4Fe−1.2Al、アトマイズ粉末)を用いたこと以外は、実施例1と同様の操作を繰り返して、本例の摺動部材を得た。
上記銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)に代えて、銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)及びコバルト基合金粉末(ケナメタルステライト社製、TRIBALOY(登録商標)T−400)からなり、これらをCu−2.9Ni−0.7Si:TRIBALOY=95:5(質量比)の割合で含む混合粉末を用いたこと以外は、実施例1と同様の操作を繰り返して、本例の摺動部材を得た。
上記銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)に代えて、銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)及びコバルト基合金粉末(ケナメタルステライト社製、TRIBALOY(登録商標)T−400)からなり、これらをCu−2.9Ni−0.7Si:TRIBALOY=85:15(質量比)の割合で含む混合粉末を用いたこと以外は、実施例1と同様の操作を繰り返して、本例の摺動部材を得た。

上記銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)に代えて、銅−ニッケル合金粉末(組成:Cu−30Ni)を用いたこと以外は、実施例1と同様の操作を繰り返して、本例の摺動部材を得た。
上記銅−ニッケル−ケイ素合金粉末(組成:Cu−2.9Ni−0.7Si、アトマイズ粉末)に代えて、銅−スズ合金粉末(組成:Cu−30Sn)を用いたこと以外は、実施例1と同様の操作を繰り返した。しかしながら、皮膜層の形成が困難であった。上記各例の仕様の一部を表1に示す。なお、各例の皮膜層の断面における第1粒子や第2粒子の割合や気孔率は、皮膜層における断面の走査型電子顕微鏡(SEM)像などの観察、及び断面走査型電子顕微鏡(SEM)像の2値化などの画像処理を複数回行うことによって、算出した。また、各例の第1粒子における析出相は、皮膜層における断面の透過型電子顕微鏡(TEM)像などの観察、及びエネルギー分散型X線(EDX)分析によって特定した。さらに、各例における摺動部材の断面における中間層の有無や塑性変形部の有無は、皮膜層における断面の走査型電子顕微鏡(SEM)像などの観察、及びエネルギー分散型X線(EDX)分析によって特定した。なお、実施例1〜実施例4及び比較例1〜比較例3のいずれにおいても、基材及び皮膜層に塑性変形部が観察された。
上記得られた各例の摺動部材等を用いて、下記の各種性能を評価した。
図10は摩耗試験装置の概略を示す断面図である。図10に示すように、バルブスプリング42、エンジンバルブ43、ステムシール44、バルブガイド45、シリンダヘッド46、46’、コッタ49等の実際のエンジンの部品を用いて、エンジンの動弁機構に似た摩耗試験装置を構築した。なお、シリンダヘッド46におけるエンジンバルブ43の着座部46Aとしては、上記各例において得られた摺動部材(1,2,3,4)を適用した。また、摺動部材(1,2,3,4)は、基材10上に形成された所定の皮膜層20を備えている。さらに、図中のエンジンバルブ43は、開き状態を示しており、エンジンバルブ43は、図示しない偏心カムにより図中矢印Yで示す上下方向に振動して、エンジンバルブ43の開閉を繰り返す。なお、シリンダヘッド46におけるエンジンバルブ43の着座部46Aの摺動面46aは、ガスバーナBの火炎Fにより高温環境下とされている。また、着座部46Aは、温度計Tにより温度が計測されている。さらに、シリンダヘッド46内には冷却水Wが循環している。
・温度:300℃(排気ポート側のシリンダヘッドにおけるエンジンバルブの着座部を想定した。)
・入力回数:540000回
上記得られた各例の摺動部材を用いて、レーザーフラッシュ法により、各例の摺動部材の熱伝導率を計測・算出して、熱伝導性を評価した。得られた結果を表2に示す(但し、比較例2及び3は測定していない。)。
上記各例の皮膜層と同様の形成条件で、上記各例の粉末を、平板状のアルミニウム基材上に、一定時間吹き付けて、粉末供給量と未付着粉末量とを計測し、付着率を算出して、成膜性を評価した。得られた結果を表2に示す。
