How can i measurement the electrochemical behavior of steel in the test solution which contained some kinds of solid particle like Fe3O4? As we kown, the actual corrosion environment contained some kinds of solid particle.
Run the experiment with a test solution without particle and again with the particles and see what comes out.
The type of test that you need to run depends upon the role that the Fe3O4 takes in the mechanism that interests you. If you are simply interested in the effect of having Fe3O4 suspended in the solution, then you can run a simple stirred test with and without the Fe3O4 to determine the change. If you are interested in a potential under-deposit type of role, then you will need to use a horizontal test specimen and then place the Fe3O4 on the surface and again run tests with and without. But you cannot stir this test. If your interest has Fe3O4 impacting the surface during flow, then you best bet is going to be a jet impingement test. And finally, if you interest is the role of mill scale that adheres to the surface of "new" steel from the mill. Then you will need to either use samples cut from "new" steel or work out a heat treatment for you specimens to create Fe3O4 on the sample surface.
Thanks Prof. Stephen N Smith
I have done some tests of steel in FeS suspended in the H2S solution, and i found the corrosion got worse with adding FeS, so i want to do more tests to study the effect of suspended particles (like FexOy, FeCO3 and sand ) on corrosion of steel.Thank you for your response.
