Despite the name, they are not liquid at room temperature. [1] Liquidmetal was introduced for commercial applications in 2003. [2] It is used for, among other things, golf clubs, watches, and covers of cell phones. The alloy was the result of a research program into amorphous metals carried out at Caltech.
J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9]
Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.
However, metal-based thermal paste can be electrically conductive and capacitive; if some flows onto the circuits, it can lead to malfunction and damage. The most effective (and most expensive) pastes consist almost entirely of liquid metal , usually a variation of the alloy galinstan , and have thermal conductivities in excess of 13 W/(m·K).
A liquid resin is then passed through the vascules and into the damage plane, allowing the cracks to be repaired. Vascular systems have a number of advantages over microcapsule based systems, such as the ability to continuously deliver large volumes of repair agents and the potential to be used for repeated healing.
Low penetration of base metal, suitable for brazing thin parts, e.g. thin-wall tubing or vacuum tubes. Does not produce severe intergranular penetrations characteristic for boron-containing nickel brazing alloys. Extensively used in nuclear industry except in high-neutron flux regions and in contact with liquid sodium or potassium.
