Inorganic Surface Coatings – Porosity Testing – Determination of Porosity in Gold or Palladium Coatings on Metallic Materials Using Gel Electrografy. ISO 15720:2001 specifies a method for determining the porosity of gold and palladium coatings on metallic materials using gel electrografy. The method involves applying an electrolyte gel to the coating, enabling the detection and mapping of pores through electrical response. Porosity is a crucial parameter for assessing the protective capability of coatings, especially in the electronics and jewelry industries, where defect-free coatings are essential for functionality and aesthetics.
