American scientists have developed an alloy of titanium and gold, which is several times harder than most steels.
According to Professor Emilia Morosan from rice University in Houston, superhard alloy can be used for the manufacture of reliable medical implants.
“He’s about 3-4 times harder than most types of steel,” she said. – It is four times harder than pure titanium, which is currently used in most dental implants and replacement joints.”
Modern titanium knee and hip implants can serve about 10 years, after which wear out and need replacement.
In addition, titanium-gold alloy may be useful in the manufacture of sports equipment, drills and other tools.
