The weathering process can significantly affect aluminum surfaces. Aluminum naturally forms a protective oxide layer when exposed to air, which provides corrosion resistance. However, over time, weathering can lead to the thinning or damage of this oxide layer, especially in harsh environments. This can result in corrosion, pitting, or discoloration. Additionally, weathering can cause physical changes such as surface roughening due to the differential erosion of the aluminum and its protective layer. In coastal areas, the presence of salt can accelerate these effects. Proper maintenance, such as regular cleaning and protective coatings, can help mitigate the effects of weathering on aluminum surfaces.
