Abstract
Official abstract text for this publication.
A method is provided for applying a transfer film to a metal surface. The method comprises electrochemically treating the metal to form an oxide layer, on to which a transfer film is applied.
First claim
Opening claim text (preview).
1 . A method of applying a transfer film to a metal surface, the method comprising treating the metal surface with micro-arc oxidation to form a metal oxide layer at the metal surface, and applying the transfer film to the metal oxide layer. 2 . A method according to claim 1 , wherein the metal oxide layer undergoes a pre-film treatment prior to applying the transfer film to the metal oxide layer. 3 . A method according to claim 1 , wherein the metal comprises aluminium, magnesium or titanium, or alloys thereof. 4 . A method according to claim 1 , wherein the transfer film is a polymer based transfer film. 5 . A method according to claim 1 , wherein the transfer film comprises one of inorganic nano-particles, metallic nano-particles or a combination thereof. 6 . A method of applying a transfer film to a casing for a device, the casing having a metal surface, the method comprising electrochemically treating the metal surface to form a metal oxide layer having a dielectric breakdown potential, the electrochemical treatment comprising applying a potential to the metal surface of the casing in an electrolytic solution, wherein the potential applied is greater than the dielectric breakdown potential of the metal oxide layer, and applying a transfer film to the metal oxide layer. 7 . A method according to claim 6 , wherein the potential is provided by a pulsed direct current. 8 . A method according to claim 6 , wherein the electrolytic solution comprises a dilute alkali composition. 9 . A method according to claim 8 , wherein the electrolyte further comprises an organic acid. 10 . A method according to claim 6 , wherein the transfer film is a polymer based transfer film. 11 . A method according to claim 6 , wherein the transfer film comprises polymer nano-particles, metallic nano-particles or a combination thereof. 12 . A method according to claim 6 , wherein the metal oxide layer undergoes a pre-film treatment prior to applying the transfer film to the metal oxide layer. 13 . A casing for a device comprising a metal layer, a metal oxide layer formed by micro-arc oxidation of the metal layer, and a transfer film on the metal oxide layer. 14 . A casing according to claim 13 wherein the transfer film is a polymer based transfer film. 15 . A casing according to claim 13 wherein the transfer film comprises inorganic nano-particles, nano-metallic particles or a combination thereof.
