METHODS OF FORMING ENHANCED-SURFACE WALLS FOR USE IN APPARATAE

摘要

A method of forming enhanced-surface walls for performing a process Is disclosed. The method broadly comprises the steps of: providing a length of material having opposite initial surfaces, said material having a longitudinal centeriine positioned substantially midway between the surfaces, each of said initial surfaces having a initial surface density; impressing secondary patterns having surface densities onto each of said initial surfaces to distort said material; and impressing primary patterns having surface densities onto each of such distorted surfaces to further distort said material and to further increase the surface densities on each of said surfaces.
