Method for production of cutting tools |
摘要 |
A method for the production of cutting tools from an iron-based alloy and having a wear-resistant coating based on interstitial phases is provided and comprises depositing the wear-resistant coating by condensing a cathode material evaporable by an arc discharge, use being made of titanium or a titanium-based alloy as the cathode material. Upon depositing a coating of a predetermined thickness, an oxygen-containing redox gas or gaseous mixture is fed into the vacuum chamber and the cutting tool is heated up to the temperature of the eutectoid decomposition in the pseudobinary 'iron-titanium' system. Thereupon the cutting tool is subjected to annealing in an atmosphere of the oxygen-containing redox gas or gaseous mixture for 10 to 40 minutes at the temperature of the martensitic transformation in the pseudobinary 'iron-titanium' system.
