Abstract
Aluminium or an aluminium alloy is prepared for plating in a known manner and a film of the desired metal not more than 0,01 m.m. in thickness is deposited; it is then subjected to treatment whereby the pores in the deposit are sealed, and the electroplating is then continued. The treatment may be effected by chemical oxidation in a bath containing sodium carbonate and potassium chromate. Sealing may also be effected by boiling in distilled water or dipping in a hot solution of nickel acetate or cobalt acetate containing a small amount of boric acid. Alternatively the pores may be filled with insoluble material, e.g. with silica by immersing first in sodium silicate solution and then in acid. The latter methods may also be applied after an oxidation treatment.
