2. Phosphate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Phosphate_conversion_coating

   Phosphate conversion coating. Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1][2][3] It is one of the most common types of conversion ...

3. Metal roof - Wikipedia

   en.wikipedia.org/wiki/Metal_roof

   Metal roof. A metal roof is a roofing system featuring metal pieces or tiles exhibiting corrosion resistance, impermeability to water, and long life. It is a component of the building envelope. The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets.

4. Hydrogen embrittlement - Wikipedia

   en.wikipedia.org/wiki/Hydrogen_embrittlement

   e. Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting ...

5. Weathering steel - Wikipedia

   en.wikipedia.org/wiki/Weathering_steel

   Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting by forming a stable external layer of rust. U.S. Steel (USS) holds the registered trademark on the name COR-TEN. [ 1 ]

6. Dry rot treatment - Wikipedia

   en.wikipedia.org/wiki/Dry_rot_treatment

   The overall cost of using the environmental approach to the treatment of dry rot is likely to be less than the orthodox approach. [ 11 ] [ 23 ] Dr. Ridout quotes a case study where an initial quote for orthodox treatment of a building was £23,000 but subsequent treatment by environmental methods resulted in a saving of one third in remedial ...

7. 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 ...
