Ｍｏ注入Ｈ１３钢明显地改善了钢表面的抗腐蚀特性，在腐蚀时间１００～２７０ｍｉｎ内，腐蚀电流密度峰值均为饱和值，极化电流密度ＪＤ是纯铁ＪＤ值的９．１％。用扫描电子显微镜观察发现，腐蚀后样品表面出现了密集的圆形和椭圆形的抗腐蚀体，其尺寸为０．５～３μｍ，这种结构具有稳定的抗腐蚀特性。随腐蚀深度的增加，这种抗腐蚀化合物暴露面积增大，因此使ＪＤ达到了饱和值。透射电子显微镜观察表明，Ｍｏ注入层中出现了Ｍｏ２Ｃ和ＦｅＭｏ弥散相，但尺寸为３～３３０ｎｍ，这比抗腐蚀体尺寸小得多，由此可见抗腐蚀体是由许多密集的ＦｅＭｏ和Ｍｏ２Ｃ结合而形成的。 Mo injection H13 steel significantly improved the corrosion resistance of the steel surface, corrosion time 100 ~ 270min, the peak corrosion current density are saturated, the polarization current density JD is 9.1% of pure iron JD value. Scanning electron microscopy showed that the surface of the sample after corrosion appeared dense circular and oval corrosion resistance, the size of 0.5 ~ 3μm, this structure has a stable corrosion resistance. As the depth of corrosion increases, the exposed area of ​​such anti-corrosive compounds increases, thereby bringing JD to saturation. Transmission electron microscopy showed that there were Mo2C and FeMo dispersed phases in the Mo injection layer, but the size was 3 ~ 330nm, which was much smaller than the size of the corrosion resistant body. Thus, the corrosion resistant body is composed of many dense FeMo and Mo2C And formed.
