7.3 Nano-Crystalline Metal and Nano Metal Foam 纳米晶金属和纳米金属泡沫
制作：孙玉超 关京瑶
armour 盔甲，装甲 ductility 延展性 wear 磨损，耐磨 nano-crystalline 纳米晶 attribute 性能，特性 dent 凹坑 crack 裂缝，开裂 degradation 退化 intact 完整无缺的 foam 泡沫技术
with a grain size a thousand times smaller
than conventional alloys without sacrificing ductility．The tiny grain size makes the metal stronger and more resistant to wear．
Biblioteka Baidu
For example，the company’s nickel— iron(50％nickel) armour plating is 2.5 times
tougher than the required specifications for U.S.military vehicles，whereas its body
armour is seven times stronger than that currently worn by soldiers and police．This
increase in strength is accompanied by a decrease in weight．
例如，该公司的镍铁（50％镍）装 甲钢板比美国军用车辆所需的规格强硬 2.5倍，而它的护身防弹衣比目前士兵和 警察穿的强七倍。这种强度的增加伴随 着重量的减少。
applications include lightweight helmets that use nano-metal foam technology，
lightweight coatings to add stiffness to tennis rackets and golf clubs，and corrosion—resistant，durable edges for skates，skis and snowboards。
该技术的关键是一个单步的过程， 生产的纳米材料晶粒尺寸比传统的合金 小一千倍而不牺牲延展性。微小的晶粒 尺寸，使金属更强和更耐磨损。
Although first tested in the lab in the early 1980s，it was another decade before the technology found commercial applications．
Integran has partnered with the U.S. Department of Defense to design new products based on these properties.
基于这些性能，Integran公司已与美 国国防部合作，设计新产品。

虽然它第一次在实验室测试是在20世纪 80年代初，但在十年之后技术才创建于商业 应用。
The breakthrough occurred in the 1990s， when Ontario Hydro，a government-owned power
company in Canada，was seeking an in-situ repair technology for the degraded tubes in its nuclear steam generator．Although nickel seemed like the ideal choice，because of its resistance to corrosion and stress corrosion cracking in nuclear reactors，its use was limited by poor mechanical strength·

lightweight alloys made of titanium and aluminum．
一家加拿大的纳米技术公司， Integran技术，开发了一个成本相对较 低的电铸工艺，可以制造出各种形式的 纳米晶，如比一些由钛和铝组成的最强 的轻量级合金具有更高的强度重量比的 板材和带材。
在消费者面前，潜在的应用包括使 用纳米金属发泡技术制造的轻巧头盔， 用轻量级涂料去增加网球拍和高尔夫球 杆的刚性，提高溜冰鞋，滑雪板边缘的 耐腐蚀，耐用性。
The key to the technology is a single— step process that produces nano-materials
