Corrosion Resistance of Nanocrystalline Materials

纳米结构材料的新颖结构和相关的独特性质赋予了它们令人兴奋的工业应用的潜力，如将药物输送到特定位置用于癌症治疗、极高灵敏度传感器、计算机/电子/通信工业的微型化、纳米机电系统、催化应用和极高强度材料。在大多数应用中，纳米材料必须在操作环境中表现出可接受的耐腐蚀性。然而，纳米结构材料的耐腐蚀性还没有被研究。该提案将研究纳米结构材料局部腐蚀和破裂的机理。

Novel structure and the associated unique properties of nanostructured materials confer potentials for their exciting industrial applications, such as drug delivery to specified locations for cancer treatment, exceptionally high sensitivity sensors, miniaturisation in computers/electronic/communication industry, nano electro-mechanical systems, catalytic applications and exceptionally high strength materials. In most of the applications, the nanomaterials have to demonstrate acceptable corrosion resistance in the operation environment. However, corrosion resistance of nanostructured materials has not been investigated. The proposal will investigate the mechanistic aspect of localized corrosion and cracking of nanostructured materials.
