Laser Turns All Metals Black

Posted by ryuzaki0 on from the bzoooom-whaaaawwwww dept.

Roland Piquepaille writes "Researchers at the University of Rochester have found a way to change the properties of almost any metal by using a femtosecond laser pulse. This ultra-intense laser blast creates true 'black metal' from copper, gold or zinc by forming nanostructures at the surface of the metal. As these nanostructures capture radiation, the metals turn black. And as the process needs surprisingly low power, it could soon be used for a variety of applications, such as stealth planes, black jewels or car paintings. But read more for additional references and a picture of this femtosecond laser system."

    The treated metal absorbs all incoming radiation, such as microwaves and lasers.

    Hint: Think "perfect stealth", not only for planes, but for your car as well. Make that cop toting the radar gun go insane.

    The black has to be as close as possible to absolute. Otherwise you'll be picked up on scanners from a long way away. You have to make your speedster totally non-ferrous, too, right down to the windings in the Bergenholm.

    "It's the wild colour scheme that freaks me," said Zaphod whose love affair with this ship had lasted almost three minutes into the flight, "every time you try to operate one of these weird black controls that are labelled in black on a black background, a little black light lights up black to let you know you've done it. What is this? Some kind of galactic hyperhearse?"

    The walls of the swaying cabin were also black, the ceiling was black, the seats-which were rudimentary since the only important trip this ship was designed for was supposed to be unmanned-were black, the control panel was black, the instruments were black, the little screws that held them in place were black, the thin tufted nylon floor covering was black, and when they had lifted up a corner of it they had discovered that the foam underlay also was black."

    Good for stuntships that only go on one un-manned mission to explode into a sun. As long as you don't mind everything being completely black.

    Does this black metal have any special properties aside from being black?

    Well, that one property alone makes it excellent for building Ford Model-Ts.

    It's so black if they had it 60 years ago you'd have to buy it in a separate store from the regular metals.
