材料科学:研究人员构想出了一种新颖独特的方法,使得金属在表面受损时可以自我修复。
SADLY for engineers, inanimate objects cannot yetrepair themselves. But work by Claudia dos Santosat the Fraunhofer Institute for ManufacturingEngineering and Automation, and Christian Mayer atDuisburg-Essen University in Stuttgart, has brought the day when they will be able to do so alittle nearer. They and their colleagues have invented a way for damaged metals to healthemselves.
对工程师来说悲哀的一面是,没有生命的物体还无法实现自我修复。但是在德国弗劳恩霍夫制造工程和自动化学会的Claudia dos Santos和斯图加特杜伊斯堡艾森大学的Christian Mayer的共同研究下,无生命物体实现自我修复那一天的到来被拉近了一点。他们与同事研发出了一种能让受损金属自我愈合的方法。
The surfaces of many metal objects are coated with other metals for protection. Iron, forinstance, is frequently galvanised with zinc. The basic idea of the new technology is to infiltratethis coating with tiny, fluid-filled capsules. When the metal coating is punctured or scratched,the capsules in the damaged area burst and ooze restorative liquids, in the form of compoundscalled trivalent chromates. These react with nearby metal atoms and form tough, protectivefilms a few molecules thick to ameliorate the damage.
