Polycrystalline boron nitride cutting tools are widely used for hard-part steel turning due to their high wear resistance and long durability, however microstructurally different composites suited machining applications. For example, low cBN content grades (cBN<50%) in continuous lightly interrupted of automotive steels the valve seat alloys; while (cBN>85%) designed provide excellent abrasion ...

The ongoing development of both engineering and functional materials is leading to new requirements in terms their surface properties [...]
