Causes of Corrosion Metal corrodes when it reacts with another substance such as oxygen, hydrogen, an electrical current or even dirt and bacteria. Corrosion can also happen when metals like steel are placed under too much stress causing the material to crack. ...
Subjecting metal to extreme heat causes it to expand in addition to impacting its structure, electrical resistance, and magnetism. Thermal expansion is pretty self-explanatory. Metals expand when subjected to specific temperatures, which vary depending on the metal. The actual structure of metal also...

None of the compounds produced by copper oxidation are as fragile. They remain on the surface, and while intermediate compounds continue to oxidize to produce the final patina, they protect the metal underneath. Copper corrosion can lead to deterioration, as occurs with copper water pipes, but th...
When silver is heated, this metal becomes soft and malleable. Although not as resistant as aluminum, silver also has high corrosion resistance features. Today, it is used for the production ofjewelryandcoins.Solar panelsalso depend on this metal, which is constantly growing in popularity. ...
Heat treatment processes alter the structure of the metal workpiece on a particle level. This induces new required properties or improves the already present characteristics of the material. Commonly seen improvements are hardness, strength, and corrosion resistance. ...
From IPC: The latest research shows excessive nickel corrosion during the immersion gold deposition causes the condition, says George Milad, national accounts manager for technology at Southington, Connecticut, USA-based Uyemura International Corp., a chemical supplier that offers ENIG chemistry to the ...
stainless steel is continuously protected by a passive layer of chromium oxide that forms naturally on the surface through the reaction of the chromium with oxygen from air or water. If the surface is scratched, it regenerates itself. This particularity give stainless steels their corrosion resistanc...
