摘要：

Visible passive films are formed on the surface of 1010 steel at 325 K in a solution of 1 N NaHCO3 + 1 N Na2CO3 at anodic potentials up to -320 mV(NHE) inclusively. For potentials below -400 mV, they are dull and contain FeCO3. For -(390-320) mV, the films are thin blackish bright. Most probably, the diffraction peaks are caused by Fe3O4-Fe2O3. For -(430-400) mV, the films are dull blackish. Probably, this color is caused by a composite of magnetite and siderite.
