-
Purity levels: Higher purity metals generally exhibit better resistance to oxidation. Impurities can create galvanic cells that promote localized corrosion. A study by Cuperus et al. (2010) indicated that low-purity alloys had reduced life expectancy due to accelerated oxidation rates.
-
Microstructure differences: The microstructure of an alloy, influenced by its composition, can affect its ability to resist oxidation. Fine-grained structures often provide greater surface area for protective oxide formation, leading to improved performance (Huang et al., 2011).
-
Environmental factors: Conditions such as temperature, humidity, and presence of chlorides interact with the alloy’s composition and purity, altering its oxidation behavior. Research shows that alloys in harsh environments (like marine settings) are more prone to corrosion if they lack appropriate alloying elements (Marcos et al., 2012).
-
Electrochemical properties: The electrochemical characteristics of an alloy, defined by its composition, also play a critical role in its oxidation tendency. Alloys with noble metals exhibit lower oxidation rates due to their low reactivity (Meyer et al., 2015).
Considering these aspects, understanding the interplay between alloy composition and purity is crucial for predicting and improving oxidation resistance in various metal applications.
