Description
本出願は、2016年11月30日に提出された大韓民国特許出願第10−2016−0162154号に基づく優先権の利益を主張し、該当韓国特許出願の文献に開示されたすべての内容は本明細書の一部として組み込まれる。
本出願は、金属フォームの製造方法及び金属フォームに関する。
高分子フォームとしては、ポリウレタンフォームであって、厚さが約5mm程度であるシート状である。前記ポリウレタンフォームの表面にチタンを公知の方式によりスパッタリングし、厚さが約100nm程度である薄膜を形成した。その後、前記チタンが表面にスパッタリングされたポリウレタンフォームをNiSO4、NiCl2又はH2BO3などが溶解されている溶液に入れ、白金電極と前記ポリウレタンフォームをそれぞれ陽極と陰極に適用する電解メッキ方式で、該当ポリウレタンフォームの表面をニッケルでメッキした。約1時間程度前記メッキを進行した後、メッキされたポリウレタンフォームを取り出した後、H2/N2の雰囲気下で誘導加熱により前記ポリウレタンフォームの除去及びニッケルの焼結を行った。誘導加熱のための電磁気場は、約350Aの電流を約380kHzの周波数で印加して形成し、電磁気場は、約3分間印加した。前記ステップを経てフィルム状の厚さ約4.2mm程度のシートを製造した。前記製造されたシートの気孔度は、約93%程度であった。図1は、実施例1で製造された金属フォームの写真である。
高分子フォームとしてアクリルフォームを適用したこと以外は、実施例1と同一に金属フォームを製造した。製造されたフィルム状の金属フォームの厚さは約4.5mm程度であり、気孔度は約95%程度であった。
実施例1と同一の方式で製造したニッケルメッキされたポリウレタンフォームを抵抗加熱方式のオーブンに適用して焼結した。このような工程を通じて実施例1と類似した物性の金属フォームを製造するにかかった時間は、約6時間であった。
Claims (11)
- 相対透磁率が90以上である伝導性金属を含む金属成分の層が表面に形成されている高分子フォームを有するグリーン構造体に電磁気場を印加し、前記伝導性金属の誘導加熱によって生成される熱により前記金属成分を焼結するステップを含み、
