It is known that during the cutting processes, due to the high contact pressures, to the high temperatures, to the relative velocities and shocks between the contact surfaces tool-part can lead to a wear more or less pronounced of the metal carbide cutting inserts. This is due to the high temperatures, the relative velocities and shocks between the contact surfaces of the tool-part and the mechanical and thermal stresses which appear on the active surfaces of the tool. This involves taking measures to increase the values of the cutting tools and/or the durability of their cutting inserts. Tool durability can be increased by various coating methods by the depositing in a vacuum of some different materials which achieve the necessary effect. Are known numerous coating processes regarding the increasing the durability of the used cutting inserts, namely by deposition of different materials, having protection role for the cutting inserts locating and clearance surfaces, methods as: vapor chemical deposition at low pressure, pulverization, ionic plating, vacuum thermal evaporation and condensation from the vapor phase. In order to increase the durability of the cutting tools, and to increase the wear resistance of the metal carbide insert, the authors propose in this paper the depositing of a titanium (TiN) thin layer and aluminum and titanium materials (AlTiN) in thin layers on these cutting inserts by the ionic plating method. This method has produced increased durability of the coated cutting insert and increased resistance to wear, higher than in the uncoated case. The values slightly vary depending on the complexity of the cutting insert profile and the dimensions of the work pieces dimensions being processed.
