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.

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 ...

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 ...

Scientists have found a promising new way to manufacture one of industry’s toughest materials—tungsten carbide–cobalt—using advanced 3D printing. Normally, producing this ultra-hard material requires ...

Researchers have created a new class of materials called “glassy gels” that are as hard as glassy polymers, but – if you apply enough force – can stretch up to five times their original length, rather ...

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 ...

Tungsten carbide–cobalt (WC–Co) is prized for its hardness, but that same property makes it unusually difficult to shape. The current process is wasteful and expensive for the yield produced, and an ...
