| Abstract: | In the process of trivalent chromium-based film-forming agent,we add auxiliary film-forming agent（cobalt salt）,black agents（nickel,iron salts）,activation agents at room temperature black passivation process.From a series of orthogonal basis for discussion of fluid composition and process conditions on the passivation effect,we can draw the best black passivation process,results can be black shiny finished product,more than 72 hours neutral salt spray test,which meets the requirements of industrial production processes. |
