Although the diamond coating can effectively prevent thermal damage to the diamond, to improve the gripping force of the diamond matrix

How to improve the metal matrix holding force of the diamond, have been studied an important direction, wherein the most common method is the surface of diamond plating Ti, Cr and other metals. Although diamond plated diamond can effectively prevent thermal damage,  polycrystalline diamond  holding force of the diamond, however, a lot of practice shows that the effect is not satisfactory [1]. Brazed diamond tools, although a large outcropping height and gripping force, but by the brazing process itself  Diamond blade , the current  Synthetic diamond  are limited to single-layer diamond abrasive tools manufacturing. After the layer of abrasive consumed without subsequent abrasive added to further improve the service life limit [2]. Therefore, to produce both a single-layer brazed diamond tools high gripping force, but also with long life sintered diamond tools, diamond tools to facilitate the blade products, to become scientists and research topic.
