The Salt Spray Test is a standardized and popular corrosion test method used to verify corrosion resistance of materials and surface coatings. Usually, the materials to be tested are metallic and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal. This is done as per ASTM B 117.
Adhesion Testing is done for plating as required in ASTM B571. Various tests such as Bend test, File test, Burnish test, Heat quench test, Peel test/ Tape test are performed in order to verify the adhesion of plating.
The Coating Thickness is typically measured using the following:an X-ray spectrometer, Thickness gauges, and / or Micrometer.
