cubic boron nitride " extremely hardchallenge, this paper points out: " diamonds are forever, but as the world's most hard materials status can be a challenge. The researchers found that, the microstructure feature size decreases to the past never reached the scale, a new level of cubic boron nitridecan achieve high hardness. These characteristics of super hard,tough and stable so that the application of cubic boron nitride could be even greater than diamond ".
