Abstract

1319658 Anodizing aluminium VEREINIGTE ALUMINIUM-WERKE A G 30 Sept 1970 [8 Oct 1969] 46564/70 Heading C7B In a process for colour anodizing Al in an electrolyte of maleic acid which may contain sulphuric and oxalic acid, the cathode 2 is housed in a container 4 of an ion-permeable material, e.g. fixed alumina silicates, containing an electrolyte of an organic acid, e.g. citric, oxalic or sulphosalicylic, with sulphuric acid.
