To design and to construct modular dies in order to easily modify work parameters.
Use of structural ceramics for heavy duty (temperature and pressure) applications, in substitution of superalloys and refractory metals. Study of almost adiabatic reactions taking advantage of insulating properties of ceramics.
In this case the most innovative issue was in the material compositions, in fact the presence of TiB2 allowed to obtain high densification and hardness.
Concerning the industrial implementation of the inserts, an optimisation of geometry is still needed.
During the projects different competitor commercial inserts based on Al2O3-TiC were tested. Through a wide microstructural and mechanical characterisation it was stated that the best cutting performance were presented by the inserts presenting the following compositions: 70%TiC-30%Al2O3.
As consequence prototype inserts in INCOSYNT projects were tailored using the same phases balance.
Theoretical densities and good wear resistance obtained in the prototype were competitive with the best commercial inserts.
Inserts were tested through laboratory machining test.
Implementation on industrial scale will follow after geometry optimisation.
