People may become sensitized to certain metals by skin contact, usually by wearing or holding consumer products (including non-metal products, like textiles and leather treated with metals), or sometimes after exposure at work. Contact with damaged skin makes sensitization more likely. Medical implants may also cause allergic reactions.
Liquid metal embrittlement (LME) is the embrittlement caused by liquid metals. Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of atoms of metal, either solid or liquid, into the material. For example, cadmium coating on high-strength steel, which was originally done to prevent corrosion.
These molecules, together with salt and other oxidation agents trapped during coating or migrating through the coating, create an electrolytic cell, causing corrosion. Blast cleaning is frequently used to clean surfaces before coating; however, with salt contamination, blast cleaning may increase the problem by forcing salt into the base ...
The good news: there are still ways to wear your favorite pieces of jewelry. The post This Is Why Your Skin Turns Green After Wearing Certain Jewelry appeared first on Reader's Digest.
Urushiol in its pure form is a pale-yellow liquid with a density of about 0.968 g/mL and a boiling point of 200 °C (392 °F). It is soluble in diethyl ether, acetone, ethanol, carbon tetrachloride, and benzene. [12] [13] Urushiol is a mixture of several closely related organic compounds.
Scientists are still unraveling the mystery of why skin conditions like eczema cause people to itch. One known cause is inflammation, which gets worse as people scratch and their skin becomes damaged.
Corrosion in the crevice between the tube and tube sheet (both made of type 316 stainless steel) of a heat exchanger in a seawater desalination plant Crevice corrosion is a localized form of corrosion occurring in confined spaces (crevices), to which the access of the working fluid from the environment is limited.
Improper use of aluminium in contact with stainless steel had caused rapid corrosion in the presence of salt water. [13] The electrochemical potential difference between stainless steel and aluminium is in the range of 0.5 to 1.0 V, depending on the exact alloys involved, and can cause considerable corrosion within months under unfavorable ...
