Improvement of the Physical and Mechanical Properties of the Cutting Tool by Applying Wear-resistant Coatings Based on Ti, Al, Si, and N

From the great variety of methods to improve efficiency cutting tools, it is necessary highlight applying wear-resistant coatings, which in recent years are increasingly used. Applying coatings on tool can significantly increase its and intensify machining modes. Mechanisms strengthening coating for materials have been analyzed under impact technological parameters condensation process structure mechanical properties, formation single multi-element based titanium nitrides, aluminum, silicon, transformation properties by obtaining complex principles designed different tools. The influence high-speed steel shown. In magnetron sputtering P6M5 samples, microhardness TiN – 20–24 GPa, AlN up 16 TiAlN 35 AlTiN 32 TiAlSiN 32–37 including while substrate 6–9 GPa. applied an instrumental basis 1,5 1,9 times higher than TiN, coatings. It was found that wear intensity without 6 with AlTiN, TiAlN, coating, 3 coating. coated characterized increased reliability stability allows processing
