High performance duplex ceramics for efficient machining of nickel superalloys - DuplexCER

Project summary

Rationale/Needs to be addressed: The DuplexCER project responds to the need to increase the efficiency and reliability of the machining processes of difficult-to-cut nickel superalloys, widely used in the aerospace and energy industry. Objectives: The aim of the project is to utilize the beneficial properties of duplex, continuous, interpenetrating oxide-carbide phases to obtain a new sintered tool material and to reduce the consumption of Critical Raw Materials (CRM: W, Co) by recycling of cutting inserts. Potential applications: The result of the project will be advanced ceramic composite dedicated mainly to the tool industry, but its other applications will also be possible, especially to work in extreme conditions (temperature, loads, abrasion). Impact and potential benefits: The proposed solution will contribute to: increasing machining efficiency and reliability, minimizing the use of CRM, to the development of closed-loop strategy, to improve health and safety of the workers.
