| Abstract: | In this paper, the surface characterization of the brass inactivated by dichromates is analyzed by SEM, and its anticorrosion property is tested. The results show that the inactivated film is compact and faultless after the following process. The brass is firstly treated by mixed acids to clear up the oxidized film, then inactivated by inactivation solution 1# for three minutes and inactivation solution 2#for seven minutes. |
