Is Rotary Friction Welding a good method to join cylinders of a metal (such as Ti alloy) and a ceramic (such as SiC).
I know that Diffusion bonding can be used in such cases. However, it has its own disadvantages - particularly its time-consuming nature.
In this context has the use of rotary friction welding (or some other friction welding process) suitable?
It is clearly suitable for shape. But are the materials themselves amenable to this? Since friction welding relies on softening the materials by heating; the dissimilar ductility and thermal properties (SiC is particularly high melting) may pose problem.
I found this which suggests that this is possible but cautions that material selection is important for determining suitablity.
This problem was inspired by a problem on one of my engineering exams. At the time of asking, the exam had already ended a day ago, so asking this question does not (in my understanding) pose any ethical issues.
