Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Both the type of metal and the environmental conditions, particularly gasses that are in contact with the metal, determine the form and rate of deterioration. Do All Metals Corr...

Today, these curves are often developed by using a metal coupon testing machine (Figure2). A small metal coupon is placed into the machine and subjected to a cyclic (or alternating) stress time history until a crack or failure occurs in the metal coupon. 现在,这些曲线,经常是使用金属试样在...

The most common reasons that metals undergo heat treatment are to improve their strength, hardness, toughness, ductility, and corrosion resistance. Common techniques for heat treatment include the following: Annealingis a form of heat treatment that brings a metal closer to its equilibrium state. It...
the state/liquid phase interface.It causes the metal at the contact surface to become a metal high ion, complex ions to dissolve or generate stable compounds such as oxyhydrides and oxides, thereby destroying the properties of the metal material. This process is called electrochemical corrosion. ...
PCB surface comprises lead, copper, nickel, and tin thin layers that become more sensitive to corrosion. At the same time, some metal substrates like gold, silver, graphite, and copper have the ability to resist corrosion. Thus, many PCB fabricators mostly cover the substrate metal, such as ...
If the corrosion is light, you can easily clean it. You can take a cotton swab and soak it in vinegar and then gently swab the terminal. It might make a fizzing sound but don’t let that frighten you. That is normal. If the corrosion is bad, you can very gently rub the area with...
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. ...
