Bicycles and airplanes use a lot of similar technologies. Both need to be strong and light. One example is bicycle wheel rims. Most are high tech aluminium (and some now carbon-fibre). For rims and other parts, anodisation is often used. It not only provides a very long lasting and clean finish, but, i am told, also strengthens the aluminium. (is that true ?). Has this ever been considered for an aircraft ? I realise that the anodisation process would have to be done during the construction, but the finish would be very hot, long lasting, and very light (no paint needed). Would the change in characteristics of the aluminium sheets from the anodisation process improve the aircraft or make the aluminium less flexible and more likely to crack after many cycles ?
