Hi everyone,
I need to do an experiment at home that tests different environmetnal conditions that facilitate corrosion of stainless steel and mild steel screws.
I have 20 screws (10 stainless and 10 mild steel screws). Each screw will be in a separate container. One pair of srews will have the same environmental conditions so I can compare corrosion of the stainless and mild steel screws.
My conditions are:
*Salt water
*Vinegar
*Screw with copper wire attached to it
*Plain distilled water.
I need the remaining pair to be my cotnrol from which I cna make comparisons. The problem is, I don't know what my control would be... Would it be just the screws in an open air container exposed to normal conditions (air with mositre) or would it be the screws in an air tight container with silica gel or would it be a screw in normal plain water?
Some mroe questions:
* Should I half-submerge my screws in their respective solutions or fully submerge them? (I was planning to half submerge them so they could be expsed to air but I don't know if this would make any difference than if they were fully submerged).
* For the copper wire which I want to act as a cathodic site, would it be better to attach the screws to a plate of copper that wrapping a thin wire around it? Would the larger surface srea make any difference?
Thanks in advance
