A method and apparatus for processing an object (4), for example an aluminium aircraft part, the method comprising: performing a first conversion coating process to dispose a first conversion coating (10) onto at least part of a surface of the object (4); partially masking the first conversion coating (10) disposed on the object (4); performing an etching process to remove, from the object (4), an unmasked portion of the first conversion coating (10) while retaining the masked portion of the first conversion coating (10) on the object (4); and performing a second conversion coating process to dispose a second conversion coating (12) onto a region of the surface of the object (4) from which the unmasked portion of the first conversion coating (10) was removed. A paint layer (14) may then be applied to, e.g., the second conversion coating (12).

Provided are an aluminum conductive member that includes an electrical connection portion excellent in conductivity and rust resistance and an electrical insulation portion excellent in long-term durability, chemical resistance, and the like, and can be manufactured at low cost, and a method of manufacturing the same.

This application provides a housing structure, a production method thereof, and an electronic device. The housing structure includes an appearance effect layer, a metal layer, a connection layer, and a non-metal layer that are laminated. The connection layer is configured to bind the metal layer and the non-metal layer. The appearance effect layer is formed after surface processing is performed on the metal layer. The housing structure includes both the metal layer and the non-metal layer. The metal layer and the non-metal layer are bound by using the connection layer, so that the housing structure has advantages of a metal layer housing and a non-metal layer housing. In addition, the appearance effect layer formed after surface processing is performed on the metal layer can ensure that the housing structure has a metallic appearance with an aesthetic appeal.
