Review Article: recent advances in metal-ceramic brazing
TL;DR: A review of recent improvements on alternative approaches to ceramic-metal joining as well as new developments on brazing are presented in this paper. But, in this paper, we focus on metallized ceramics and the selection of filler alloys, since in a scenario that includes joining by laser and direct bonding with liquid transient phases, Brazing remains the most widely used approach to joining as a result of its low-cost and possibility to join intricate geometries for large-scale production.
