“Metal glue” can replace welding

Metal glue

Usually welding or brazing is used to connect two metal parts. However, in some cases (installation of electronic circuits, repair of gas pipelines), the thermal effect is undesirable. To solve this problem superglue MesoGlue, developed by experts of the Northeastern University of Boston, headed by Professor Hanchen Huang, will help.

Adhesive is intended for joining products from metal and other materials at normal room temperature. When it was created, nanotechnology was used. MesoGlue consists of microscopic nanorods with a metal core. Some of them are covered with indium, and some with gallium.

Adhesive instead of welding

An indium nano-layer is applied to one of the surfaces to be glued together, and to the other – gallium. Rods, like the hairs of two connected brushes, enter the free space and come into contact with each other.

In this case, a liquid is formed, with which the indium and gallium rods react. As a result, after a while a strong monolith is formed, providing a connection that is in no way inferior to welding or soldering.
