Sandia National Laboratories engineers wear-resistant metal alloy

摘要

The materials science team at Sandia National Laboratories, Albuquerque, N.M., has engineered a platinum-gold alloy that it believes to be the most wear-resistant metal in the world. It's 100 times more durable than high-strength steel, making it the first alloy, or combination of metals, in the same class as diamond and sapphire, nature's most wear-resistant materials.
