Web1 de dez. de 2024 · The high chemical activity of the friction pair will facilitate the interfacial mechanochemical reactions, by lowering the activation energy of the generated interfacial bond bridges. However, after the formation of bond bridges at the interface, the process of “Ga−As” bond breaking is hardly affected by the friction pair chemical activity.
WebTherefore materials with high chemical resistance are less likely to corrode. Highly chemical resistant materials such as acrylic resins are also regarded as functionalize for corrosion-resistant materials because of their resistance to chemical activity. Chemical resistance also can affect the physicochemical properties.
