thanks for the quick reply. Attached is the image of structure i need to analyze for stress and displacement. Red arrows are load - should these applied as force or pressurehttp://files.engineering.com/getfile.aspx?folder=29f681dc-ce3a-4f42-90f5-59da69521e9b&file=03_0.125_Sliding_Load.JPG
The Surroundng surfaces are painted. Only the mating surfaces are not painted so that they can act as ground surfaces. I need to know that how the mating surface can be used as ground while preventing the rust.
We have an enclosure for electronics and painted through except for mating surfaces. The mating surfaces are not painted since act as grounding. The mating surfaces are starting to rust.
Is there anyway to avoid the rust and still maintain the same as ground surface.
