Abstract

Measurements have been made on the wear resistance of ceramic cutters based on silicon nitride and bearing titanium nitride coating during the continuous machining of ShKh15 steel. The coatings were deposited by cathode sputtering. Use was made of continuous coatings and discrete ones in the form of ordered fragments. The continuous TiN coatings raise the wear resistance by a factor of 1.7, while the factor is 2.2 for the discrete TiN coatings. The performance of the tool is also improved in the case of the discrete coatings as the cutting speed and feed can be raised by comparison with tools with continuous coating.
