Method of manufacture of electrochemically textured surface having controlled peak characteristics

摘要

Textured surfaces comprised of peaks which have been electrochemically deposited on a substrate are prepared using a pulsed direct current process. Typical substrates are machine components such as a machine roll. Improved textured surfaces are made according to the invention by controlling the density, uniformity and size of the peaks using a pulsed direct current process. Accordingly, the peak characteristics are predetermined by selecting a pulse wave form having specific current density and pulse interval parameters as well as a total deposition time which will deposit peaks having desired characteristics on the substrate.
