37+ Trivalent Chromium Plating Process Pics
37+ Trivalent Chromium Plating Process Pics. Processes using trivalent chromium solutions (results have not been published). What are the basic differences in the plating processes of chromium iii and chromium vi.
On account of environmental concerns trivalent chrome is used instead of hex chrome.
Zinc electroplating, decorative and hard chromium plating, nickel, copper, silver, gold, and tin electroplating are covered faraday will discuss recent research work on the development of a fully reach compliant trivalent chromium plating process to replace hard hexavalent chromium plating. Chromium plating is traditionally made from a solution of chromic acid (cro3 which forms h2cro4 after dissolving in water) and sulfuric acid (h2so4) using insoluble anodes. The process also utilizes insoluble anodes. Processes using other metals (other than chromium) with and without nickel salts.
