ELECTROCHEMICALLY TEXTURED SURFACE HAVING CONTROLLED PEAK CHARACTERISTICS AND THE METHOD OF MANUFACTURE

摘要

Textured surfaces comprised of peaks which have been electrochemicallydeposited on a substrate are prepared using a pulsed direct current process.Typical substrates are machine components such as a machine roll. Improvedtextured surfaces are made according to the invention by controlling thedensity, uniformity and size of the peaks using a pulsed direct currentprocess. Accordingly, the peak characteristics are predetermined by selectinga pulse wave form having specific current density and pulse intervalparameters as well as a total deposition time which will deposit peaks havingdesired characteristics on the substrate.
