ABSTRACT:
A method and apparatus are described for making a coldplate. A first component of, for example copper, is explosion welded to a second component of, for example aluminum. The first metal component has a top surface opposite the second metal component and at least one channel proximate the top surface adapted to carry a cooling fluid. The coldplate can be used as an interior wall for a plasma chamber.
