2. Zinc chromate - Wikipedia

   en.wikipedia.org/wiki/Zinc_chromate

   Zinc chromate, Zn Cr O 4, is a chemical compound, a salt containing the chromate anion, appearing as odorless yellow powder or yellow-green crystals, but, when used for coatings, pigments are often added. [2][3][4] It is used industrially in chromate conversion coatings, having been developed by the Ford Motor Company in the 1920s. [5]

3. Galvanic corrosion - Wikipedia

   en.wikipedia.org/wiki/Galvanic_corrosion

   Galvanic corrosion. Corrosion of an iron nail wrapped in bright copper wire, showing cathodic protection of copper; a ferroxyl indicator solution shows colored chemical indications of two types of ions diffusing through a moist agar medium. Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical ...

4. Prepainted metal - Wikipedia

   en.wikipedia.org/wiki/Prepainted_metal

   Prepainted metal. According to EN 13523-0, a prepainted metal (or coil coated metal) is a ‘ metal on which a coating material (e.g. paint, film…) has been applied by coil coating ’. When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or ...

5. Corrosion inhibitor - Wikipedia

   en.wikipedia.org/wiki/Corrosion_inhibitor

   A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. [1] The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics. Corrosion inhibitors are common in industry, and also found in over-the-counter ...

6. Salt spray test - Wikipedia

   en.wikipedia.org/wiki/Salt_spray_test

   The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

7. Zinc flake coating - Wikipedia

   en.wikipedia.org/wiki/Zinc_flake_coating

   Because electrolytically zinc-plated surfaces provide comparatively little corrosion protection, and in the case of galvanic zinc coatings on high-strength steel (e.g. category 10.9 and 12.9 high-strength bolts) there is a risk of hydrogen embrittlement, the industry needed a better corrosion protection system.
