Abstract (en)
[origin: WO2016097695A1] 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).
