Joining Silicon Carbide to Austenitic Stainless Steel through Diffusion Welding

摘要

In the thesis the results are presented of a study dealing with joining siliconcarbide to austenitic stainless steel AISI316 by means of diffusion welding. Welding experiments were carried out without and with the use of a metallic intermediate, like copper, nickel and copper-nickel alloys at various conditions of process temperature, process time, mechanical pressure and interlayer thickness. Most experiments were carried out in high vacuum. For reasons of comparison, however, some experiments were also carried out in a gas shielded environment of 95% vol. Ar and 5% vol. H2.
