| abstract |
A method of polymer sealing an anodised or unanodised surface (whether of pure metal or an alloy) having a content of at least one of the group consisting of magnesium, beryllium, titanium, zirconium, hafnium, zinc and aluminium which involves a preliminary treatment with a deactivating agent (e.g.: HF in some cases) to render the surface to be sealed substantially devoid of ionisable species and thereafter electrophoretically treating the deactivated surface with a resin suspension to provide a coating which is subsequently cured to its polymer. The procedure has particular application to magnesium and magnesium alloys and to fabricated structures thereof with, for example, aluminium or aluminium alloys. |
