Corrosion on polymers is not easy to discover, it may happen that the material looks the same, but it can be embrittled and have lost its mechanical strength. 3 reasons why corrosion test is conducted. Defining corrosion resistance of materials and how to develop new corrosion resistant alloys. Which factors bring metals to corrode?When metals come to contact with an electrolyte containing dissolved reactive substances, such as water (water is never present in pure form, gases and salts dissolved in water help corrosion), 2 metals electrons flow away to the cathodic area of the metal where they react with oxygen and start forming rust.

For more information, please fill out the form and send your message: Angelantoni Test Technologies has been a world leader since 1952 in the design and manufacture of a wide range of environmental test chambers, from simple bench-top chambers for T and RH tests to complex high-tech systems, such as thermo-vacuum chambers for aerospace applications and calorimeters. Polymers that are mechanically stressed in a chemical environment can crack on the surface; cracks can then propagate into the material. But there are also other factors that can ease the corrosion process: hbspt.cta._relativeUrls=true;hbspt.cta.load(3069617, '33e46e13-8fef-4413-99df-0c89270b5117', {"useNewLoader":"true","region":"na1"}); We are used to deal with rust to describe the corrosion of iron or steel, as metals can corrode easily; but these are not the only materials that suffer the effect of corrosion. The Yucca Mountain Nuclear Waste Repository, as designated by the Nuclear Waste Policy Act amendments of 1987,[2] is a proposed deep geological repository storage facility within Yucca Mountain for spent nuclear fuel and other high-level radioactive waste in the United States.
