Technical Research on the Surface Oxide Layer of 30MnSi Steel
The surface oxide layers of 30MnSi with different colors were detected and analyzed using stereomicroscope,metallographic microscope,scanning electron microscope,and energy dispersive spectrometer.The microstructure,thickness,density,and chemical composition of the surface oxide layers of 30MnSi were studied,providing data support for improving surface quality in the later stage.
