Method for creating a chromium-plated surface with a matte finish
Abstract:
A method for creating a chrome-plated surface having a matte finish that typically includes: controlling a resistance of a current bridge circuit; depositing a first chromium layer on a substrate positioned in a chromium bath, wherein the first chromium layer is deposited by supplying current from a power source that is electrically connected to the substrate and to anodes positioned in the chromium bath; etching the first chromium layer by engaging a current bridge that closes the current bridge circuit; depositing a first intermediate chromium layer, wherein the first intermediate chromium layer is deposited by supplying current from the power source; etching the first intermediate chromium layer, wherein the first intermediate chromium layer is etched by engaging the current bridge; and depositing a final chromium layer, wherein the final chromium layer is deposited by supplying current from the power source.
