Description
図1は、本実施の形態の摺動部材の概要を示す斜視図、図2A、図2B、図2C、図2D及び図2Eは、本実施の形態の摺動部材の製造方法の一例を示す説明図である。
次に、各図を参照して、本実施の形態の摺動部材の製造方法について説明する。
以下の表1に示す組成の合金材料で、摺動層及び裏金共に焼結体で構成すると共に、摺動層となる上述した第2の焼結体層3にブラスト処理を施した実施例と、鋼材の裏金の表面に焼結体で摺動層を形成し、プレスによる圧延加工を施した比較例で、硬度を比較した。硬度の測定は、マイクロビッカース硬さ試験で行った。
上述した実施例と比較例の摺動部材で、摺動層の表面形状を比較した。
上述した表面形状と硬度の違いが浸食といった耐久性に及ぼす影響を検証するため、実施例及び比較例の摺動部材を、ピストンポンプの軸受に適用して試験を行った。試験条件は以下の通りである。
サイクル数:25万回サイクル(ON:1sec,OFF:1sec)
油温 :60℃(油圧作動油:VG32相当油)
軸回転数 :N=1800rpm
