Abstract: The design of interfaces, coupled with suitable joining materials and joining technologies, is a key parameter in component manufacturing and surface pre-treatments are crucial steps for the production of robust and reliable bonds. In this work, plasma pre-treatments on SiC and Si3N4 are studied and discussed. The pre-treated joined samples have shown a higher mechanical strength than the reference value (lapped surfaces) and the increased adhesion at the ceramic/adhesive interface has led to cohesive failure of the adhesive.
