Abstract:

Ti(C,N)-MoNi cermets cutting tool inserts have been produced by cold compaction and sintering of commercial ready to press granules. The inserts have been characterized by hardness, density measurements and SEM observations. The cutting edges of sintered inserts were sharpened by laser grinding before coating with a PVD nitride layer by High power impulse magnetron sputtering. Instrumented scratch tests were conducted to evaluate the coating adhesion on both reference cemented carbide and experimental cermet inserts.
