Hi, materials engineering noob needs Your help. I've got a problem. What i need to do, is to somehow join aluminum and ceramics in a rather dynamic application. Ideally, i would like do achieve it without using any other substance, i.e. glue. What i need to work with: aluminum rod, about 100 inches long, 1" internal diameter, 1/8 inch thick wall; ceramics - let me just call it clay, i can either have it in 'soft form', before burning, or hardened, after burning; as far as equipment goes, i can use ceramics oven, as well as give it to metal shop, so all the metal working equipment is available - those guys do not work with ceramics, however. What is the desired output: same aluminum rod, lined inside with a ceramic layer, about 1/4" thick. The remaining internal diameter would therefore be about 1/2". My question: how to do it? Could i simply mold the internal ceramics "rod", slide it inside the aluminum one and then burn? Would there be any permanent bonding between the two substances? if not, is there any other way? Thank You in advance, cheers.
