Al2O3passzív
Al2O3passzív, also known as aluminum oxide passivation, refers to a process that forms a protective oxide layer on the surface of aluminum and its alloys. This layer is primarily composed of aluminum oxide (Al2O3) and forms spontaneously when aluminum is exposed to oxygen. The passivation process can also be enhanced through chemical treatments.
The native aluminum oxide layer is very thin, typically only a few nanometers thick. However, it is
In industrial applications, controlled passivation is often employed to improve the corrosion resistance, wear resistance, and
The effectiveness of Al2O3passzív depends on factors such as the alloy composition, the treatment method, and
