The cost of anodising and colouring of small aluminium articles meant for lower sewice life is quite high. In this context chemical oxidation of aluminium and subsequent colouring with organic dyes has a good potential. This process is useful for the bulk treatment of small aluminium articles like rivets, bolts, nuts, screws, nails, washers, chains, jewellery items, etc. Such small articles are very difficult to anodise using conventional methods. Chemical polishing prior to colouring improves the brilliancy of the colour so produced. These are highlighted in this paper.
