Hard materials keep modern life moving, from drill bits to cutting tools. One of the toughest is tungsten carbide with cobalt, often shortened to WC–Co. It lasts a long time and resists wear, but ...

It was found that the hard material must be capable of conducting ions, and the soft material has to contain salt ions. The scientists believe that a chemical bond forms when the two materials ...

Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the ...

The approach uses 3D printing to produce WC-Co cemented carbides - ultra-hard materials used in cutting and construction tools - while reducing the waste and cost of conventional manufacturing.

UB chemistry researcher Eva Zurek is a key partner on a new $7.5 million effort to discover inexpensive materials hard enough to join two pieces of steel together through a process called friction ...
