vacancy migrationとは 意味・読み方・使い方

To solve such a problem that, when Cu-plated solid lubricant is mixed with Cu-Sn alloy powder and sintered, the solid lubricant is firmly joined with a copper alloy matrix since Sn in the alloy powder is diffused into the Cu plated layer in a process where the ordinary sintering phenomena such vacancy elimination and grain boundary migration are developed however the conformability of the sintered copper alloy is deteriorated.例文帳に追加

Ｃｕめっきを施した固体潤滑剤をＣｕ−Ｓｎ合金粉末と混合して焼結すると、空孔の消滅、粒界移動などの通常の焼結現象が起こる過程で、被覆のＣｕめっき層に合金粉末中のＳｎが拡散する結果、固体潤滑剤は銅合金マトリックスに強固に接合されるが、焼結銅合金のなじみ性を劣化させる問題を解決する。 - 特許庁
