Abstract
Bonded surfaces are formed by adhering first nanorods and second nanorods to respective first and second surfaces. The first shell is formed on the first nanorods and the second shell is formed on the second nanorods, wherein at least one of the first nanorods and second nanorods, and the first shell and the second shell are formed of distinct metals. The surfaces are then exposed to at least one condition that causes the distinct metals to form an alloy, such as eutectic alloy having a melting point below the temperature at which the alloy is formed, thereby bonding the surfaces upon which solidification of the alloy.
Claims39
A method for bonding surfaces, the method comprising the steps of:
- a) adhering first nanorods to a first surface;
- b) forming a first shell on the first nanorods;
- c) adhering second nanorods to a second surface;
- d) forming a second shell on the second nanorods, wherein the first and second nanorods are formed of distinct metals, wherein the first shell and second shell are formed of a common material, and wherein the common material is a magnetic metal or magnetic metal alloy;
- and
- e) exposing the surfaces to a magnetic field that ruptures the first and second shells and causes the distinct metals to form a eutectic alloy.
A method for bonding surfaces, said method comprising the steps of:
- a) adhering first nanorods to a first surface;
- b) forming a first shell on the first nanorods;
- c) adhering second nanorods to a second surface;
- d) forming a second shell on the second nanorods, wherein the first and second nanorods are formed of distinct metals, wherein the first shell and second shell are formed of a common material, and wherein the common material is a polymer;
- and
- e) exposing the surfaces to at least one condition that causes the distinct metals to form a eutectic alloy.
