DEVELOPMENT OF NEW BORIDE BASED CERMETS AND CERAMICS

Objective



THE AIM OF THE PROJECT IS TO DEVELOP PROCESSES, BASED ON SCIENTIFIC INVESTIGATIONS, FOR THE PRODUCTION OF NON-POROUS CEMENTED BORIDES AND BORIDE-BASED CERAMICS, BY PRESSING, SINTERING AND HOT ISOSTATIC PRESSING, IN ORDER TO PRODUCE WORK PIECES WHICH WILL BE PRACTICALLY TESTED IN THE FOLLOWING FIELDS OF APPLICATIONS: CUTTING TOOLS, ENGINEERING AND MINING TOOLS, AND WEAR PARTS. THE PROGRAMME WILL BE AS FOLLOWS:

- INVESTIGATION OF THE WETTING BEHAVIOUR OF NON POROUS BORIDES (TIB2, ZRB2, CRB2...) BY LIQUID METALS (FE, CO, NI...) AND THEIR ALLOYS (INFLUENCE OF ADDITIONAL ELEMENTS, TEMPERATURE, ATMOSPHERE...). SELECTION OF 4 TO 6 BINDING ALLOYS;- DETERMINATION OF THE OPTIMUM CONDITIONS FOR MILLING, SINTERING AND HIPPING OF THESE CERMETS AND TWO BORIDE-BASED MONOLITHIC CERAMICS;
- STRUCTURAL CHARACTERIZATION:
- DETERMINATION OF THE MAIN PHYSICAL, MECHANICAL AND CHEMICAL PROPERTIES;- STUDY OF THE MACHINING OF THE NEW CERMETS;
- PRODUCTION ON INDUSTRIAL WORKPIECES AND TESTING OF THEIR BEHAVIOUR IN COLLABORATION WITH CUSTOMERS;
- STUDY OF A POSSIBLE RECYCLING OF WORN PIECES.
