| Abstract: | The components and microstructures of weld join on hot-rolled plates of 409L ferritic stainless steel in three zones((BM),(HAZ)and(WM)) were analyzed with electron probe microanalysis(EPMA)and metallurgic microscopy.The characteristic parameters of polarization curves of these three zones in 10%H2SO4 solution were measured by using electrochemical method.Then the immersion corrosion test was conducted at room temperature for 24 hours.The result showed that,in these three zones,the differences in component,m... |
