Wear resistant duplex interpenetrating ceramics and ceramic-based composites intended for dry machining of alloys and other tribological applications
The PhD position is opened for an Early State Researcher to be involved into materials science and tribological research of novel machining tool materials (inserts). These machining tools should be suitable for dry cutting of hard-to-cut materials. For their production the reduced amount of Critical Raw Materials should be used. Novel materials should reduce the waste of cutting fluids (usually used to cool down the tool, etc) and risk of health issues associated with use of such liquids. The main work will be associated with fulfillment of activities of European M-ERA.NET project.

The project aims at utilization of beneficial properties of duplex interpenetrating ceramics and ceramic-based composites to obtain optimized sintered machining tool materials with improved wear resistance.
The objective is development of innovative wear-resistant materials with reduced amount of Critical Raw Materials (CRM: Co, W, etc) for machining of hard-to-cut materials. It is also intended to utilize powders of recycled material.
The goals of the project are: (1) To reduce price of cutting tool material while maintaining high wear resistance. (2) To use Spark Plasma Sintering (SPS) and/or Pressure-less Sintering for production of optimized materials. (3) To obtain materials with sufficiently high hardness and fracture toughness. (4) To enable dry machining of hard-to-cut materials to reduce waste and risk of health issues. (5) To develop technology for recycling of cutting inserts.
