| Abstract Scope |
The production of fully dense components made of multiple layered powders has been a long-standing challenge, and it is currently raising even more attention with the advent of additive manufacturing. Multi-layered ceramics and ceramic-metal composites are ubiquitous (capacitors, antennae, catalytic membranes, batteries…) and AM leads per se to layered components that in most cases need to undergo a sintering step. But their co-sintering is prone to be affected by anisotropy, distortions and even cracking, due to the different densification kinetics of each constituent. By modeling the sintering process in a simple finite-element-based platform, strategies to minimize these issues are defined. The stresses developed at the interfaces turn out to be key, and process optimization guidelines are drawn based both on the interface geometry and on the sintering routine. |
