Abstract Scope |
Binder Jet Printing (BJP) is one of the 3D-printing fabrication techniques. BJP is a non-thermal and non-melting process, where fabricating parts performed using binder deposition head instead of powerful laser or electron beam. Thus, the list of applied materials not limited by their melting point, and can be much wider than for SLM/EBM processes.
Additionally BJP provides a possibility to print highly porous (about 50%) "green bodies", ideal for subsequent infiltration of liquid metals.
In this study, the optimal fabrication process of Reaction Bonded Silicone Carbides (RBSC) including BJP, additional optimal carbonization (to achieve the lowest possible amount of residual silicon) process and Capillary Liquid Silicon Infiltration (CLSI) has been investigated. An effect of additional carbonization of BJ 3D-printed porous SiC on the residual Si-content after the CLSI, has been explored. The microstructure as well as mechanical and physical properties of the 3D printed RBSC have been investigated and presented. |
