Ultrahard boron nitride material through a hybrid laser/waterjet based surface treatment
We report a dual phase boron nitride (BN) material composed of 50% cubic and 50% wurtzite phases that has the same level of hardness as polycrystalline diamond. The dual phase BN material was initially synthesized from high pressure and high temperature consolidation of powder materials and subsequently, a laser/waterjet heat treatment (LWH) was applied to the material surface. The LWH process con
