    摘要:

    采用微電鑄技術對生物表面形貌進行直接復制以成形出與生物原型形貌相接近的仿生表面,是生物復制成形技術由高聚物成形向金屬沉積成形擴展的新途徑。以鯊魚皮為生物模板,針對其表皮微形貌結(jié)構(gòu)特征,通過傾斜濺射方式先在其鱗片表面沉積導電層,進而采用正負間斷脈沖電流對鯊魚皮生物模板進行微電鑄復制,成形出鯊魚皮微電鑄模板及仿鯊魚表面。復制精度分析結(jié)果表明,采用微電鑄生物復制成形工藝可以實現(xiàn)對鯊魚皮外端溝槽微形貌的高逼真復制,證明該工藝可以應用于微尺度、復雜生物表面形貌的直接復制。

    Abstract:

    Direct replication of biological surface morphology using micro-electroforming method to form biomimetic surfaces with relatively vivid morphology is a new process extension from polymer forming to metal deposition forming of the bio-replicated forming technology. Taking shark skins as the replication templates, the conducting layer was deposited on the shark scales with the inclined magnetron sputtering process according to the structural characteristics of shark skins. Then the micro-electroforming process adopting the pulse-reverse currents was conducted. Finally the shark skin micro-electroforming template and the biomimetic shark skin were obtained. The preliminary analysis on replication precision indicated that the micro-electroforming method could be used to replicate the outward morphology of the shark skins with good precision, which validated the application of the bio-replicated forming technology in the direct replication of the complex and microscale biological surface morphology.
