Abstract
The method produces an article which has a first zone comprising a nonoxide ceramic material (which materials cannot be soldered or welded) and a second zone comprising a different, softer material such as one which can be soldered or welded to other parts. A transition layer between the zones of the article comprises both materials for bonding the zones together. The method forms the article from powders with heat and pressure.
