Description
ピストン冠面に見立てた試験片を作製し、その表面に表面処理部を形成する。ピストン母材の材料と同様のアルミニウム合金(4032−T6)から円盤状の試験片を作製し、その上面に直径30mm、深さ5mmの凹部を形成した。凹部に粉末51を所定量だけ凹部に充填した後、直径30mmの回転工具を800rpmで回転させながら荷重をかけて粉末51を試験片の凹部に押込んだ。回転工具の下端が凹部の底面から1.5mmの高さの位置となるように回転工具を所定時間保持した後、回転工具を凹部から引き抜いた。
表面処理部における断熱特性を評価した。具体的な評価方法について図11を参照して説明する。図11は評価方法を示す概念図である。真空チャンバ62の内部に表面処理部を形成した実施例および比較例の試験片61を配置し、レーザー光源64からレーザー光を出射させ、試験片61の表面諸部に照射する。この状態で、赤外線カメラ63により試験片の表面温度の変化を測定する。
ピストン冠面に表面処理部を形成する手順について説明する。図5に示したフローチャートに沿って、ステップS1として説明した通り、ピストンの鋳造を行った、ピストンの母材としてはアルミニウム合金(AC8A)を材料に用いた。次に、ステップS2として説明した通り、ピストンの粗材に対して一次機械加工を施した。次に、ステップS3〜S5として説明した通り、材料充填、摩擦撹拌接合、および回転工具の引抜きの一連の工程を2回繰り返し、表面処理部を形成した。次に、ステップS6として熱処理を施した後、ステップS7として二次機械加工により仕上げ形状に加工し、所定のピストンを作製した。なお、粉末を充填する凹部は一次機械加工時に直径30mmで深さ5mmの穴状に加工することにより形成した。
図4に示した構成の表面処理部を形成する手順について説明する。図4に示した表面処理部は、ピストン冠面に形成された凹部の表面に、第3層と第2層をこの順序で交互に3回繰り返して形成された上に最上層として第1層が設けられた構成である。
