Nano molding technology (NMT) has shown great potential in the preparation of metal/resin composites, which can integrate resin and metal into a lightweight, high-strength metal matrix composite. However, due to the poor interfacial bonding strength between metal and polymer, the application of the metal/polymer composites is limited. In this paper, we proposed a novel method to improve the bonding strength between Fe–Co–Ni alloy and epoxy resin by Nano Perfusion Technology (NPT), featuring in situ growth of carbon nanotubes (CNTs) in the pores on anodized Fe–Co–Ni alloy porous surface, followed by a perfusion of epoxy resin throughout the pores that had been in situ grown CNTs. Due to the “anchor effect” of CNTs, the bonding strength between the epoxy and the alloy matrix is improved. The results showed that the interfacial bonding between the in situ CNTs-modified alloy and the resin was significantly improved compared to the metal-resin composites surface treated with T-treatment in traditional method of NMT. The maximum interfacial bonding force of the alloy-CNTs/epoxy composite reached up to 691.80 N, which was 460, 315, and 267% higher than those by mechanical treatment, without CNTs and T-treatment, respectively. This work provides a new approach to protect metals or alloys from environmental corrosion, impact damage, and so on.

通过CNTs原位生长有效改善纳米灌注复合材料界面结合的方法

纳米成型技术（NMT）在金属/树脂复合材料的制备中显示出巨大的潜力，可以将树脂和金属整合到轻质，高强度的金属基复合材料中。然而，由于金属和聚合物之间的不良界面粘合强度，金属/聚合物复合材料的应用受到限制。在本文中，我们提出了一种通过纳米灌注技术（NPT）来提高Fe–Co–Ni合金与环氧树脂之间的结合强度的新方法，其特征在于在阳极氧化的Fe–Co上的孔中就地生长了碳纳米管（CNTs）。 -Ni合金多孔表面，然后在原位生长的CNT的整个孔中灌注环氧树脂。由于碳纳米管的“锚固效应”，环氧树脂和合金基体之间的结合强度得到了提高。结果表明，与传统的NMT方法中经T处理的金属树脂复合材料相比，原位CNTs改性的合金与树脂之间的界面结合得到了显着改善。合金-CNTs /环氧树脂复合材料的最大界面结合力达到691.80 N，分别比不进行CNTs和T处理的机械处理分别高460、315和267％。这项工作提供了一种保护金属或合金免受环境腐蚀，冲击破坏等的新方法。分别比未进行CNT和T处理的机械处理高出267％。这项工作提供了一种保护金属或合金免受环境腐蚀，冲击破坏等的新方法。分别比未进行CNT和T处理的机械处理高出267％。这项工作提供了一种保护金属或合金免受环境腐蚀，冲击破坏等的新方法。
