Artificial joints, as well as natural joints, basically use the same method as all sorts of machinery does, namely, lubrication.
They are made of either prosthetic implant or bone cement.
It probably does. The muscles skin and connective tissues will react differently to the extreme heat and may cause arms and legs and other joints to tighten for a few moments. It seems it would be a distressing thing to witness, especially if it is the cremation of a loved one. I doubt that most establishments would allow it.
Because the material is better when working properly they repair themselves up to a point.
Yes. Many people have artificial joints, and the Jarvik heart is 'bionic'.
