WebIn general, for electroplating to provide superior corrosion resistance, a metal which is more inert than the base material should be chosen. In addition, thicker deposits and tighter grain structures will result in enhanced resistance to corrosion. A surface finish which is less porous will prevent oxidation and subsurface galvanic migration. WebThis means you can prevent the formation of pores by polishing the surface thoroughly before electroplating. Choosing to apply an underplate: An underplate cannot prevent pores from forming, but it can prevent corrosion creep. When pores stop at the underplate layer, corrosion products from the base material cannot escape to tarnish the surface.
