[Problems] This invention is intended to provide a method for preventing corrosion and adhesion caused by the ammonium sulfate and ammonium chloride. SOLUTION: A crude oil refining process as an additive or derivatives of choline, in particular the general formula [5] By injecting the derivative ...
Destructive damage caused by chemical or electrochemical reactions in metals subjected to environmental influences. It can be said that almost all metal products, in a certain environment, will have some forms of corrosion, and the copper sleeve is also a metal product, which n...
Phased array ultrasonics (PAUT) are used for a wide range of critical assets inspection. PAUT can detect cracks, voids, and pits caused by corrosion.
Corrosion lowers the ability of metal sections of bridges to bend and twist. Maintaining this integrity is critical, especially in areas that experience earthquakes, shifting traffic loads, or extreme weather, especially winds.Some of history’s greatest bridge collapseswere caused by structural elements...
Corrosion mechanisms in the wood industry, especially caused by tannins In order to improve the lifetime of cutting knives in the wood processing industry, a study has been undertaken to find out which wear process is primarily... H Winkelmann,E Badisch,M Roy,... - 《Materials & Corrosion...
Asbestos is a group of six naturally occurring mineral fibers. It was used in thousands of U.S. products because it is resistant to heat, electricity and corrosion. Asbestos is carcinogenic and known to cause mesothelioma, lung cancer and other cancers....
The steel used on these coins was fairly low grade, infused with carbon, and topped with zinc to add a touch of luxury. The zinc was meant to aid the coin’s rust resistance since iron is so susceptible to oxidation and corrosion (aka rust). But starting in 1942, experimental coins wer...

suffer substantial losses as a result of degradation in aqueous environments6. Corrosion of Al alloys is both costly and dangerous7,8,9. Three factors deserve particular attention in that context. First, Al alloys are increasingly exposed to harsh environmental conditions for which they had originall...
a腐败的本义是指有机体因微生物的侵蚀而分解变质的现象,既指质变过程又指质变结果(寻民利,2003)。 The corrupt original meaning is refers to the organism to decompose the deterioration because of microorganism's corrosion the phenomenon, both refers to the qualitative change process and to refer to the...
