Electrochemical analysis of the ASTM F75 alloy at different pH values and temperatures
(Wiley, 2017-02-27)
The electrochemical behavior of ASTM F75 alloy was analyzed in a sodium chloride solution at pH values of 5, 7, and 9 and temperatures of 37 and 42 °C. The tests were performed in samples corresponding to two different ...
Corrosion of nonferrous metals and their alloys
(Hindawi, 2018-05-31)
Corrosion is the result of the interaction of a material (metal) with its environment.
Thecorrosion process depends on the properties of both metal (and alloy) and surrounding environment. Usually, the more important ...
