20150068906 | PHOTOCATALYST - The present invention relates to a photocatalyst and a method of manufacturing a photocatalyst. More specifically, the present invention relates to a high surface area TiO 2 photocatalyst formed by electrolytic discharge oxidation (EDO) of a substrate comprising titanium. A flexible high surface area photocatalyst architecture comprising a compliant, cohesive, well-adhered and highly porous surface layer of the anatase phase of titanium dioxide is provided. The highly porous surface layer of the anatase phase of titanium dioxide is formed in a single step by the electrolytic oxidation of a titanium surface on a permeable, flexible, and electrically conductive substrate sponge structure. | 03-12-2015 |
20140318974 | CORROSION AND EROSION-RESISTANT MIXED OXIDE COATINGS FOR THE PROTECTION OF CHEMICAL AND PLASMA PROCESS CHAMBER COMPONENTS - There is disclosed a method for producing corrosion and erosion-resistant mixed oxide coatings on a metal substrate, as well as a mixed oxide coating itself. A surface of the substrate metal is oxidised and converted into a first coating compound comprising a primary oxide of that metal by a plasma electrolytic oxidation (PEO) process. One or more secondary oxide compounds comprising oxides of secondary elements not present in conventional alloys of the substrate metals at significant (>2 wt %) levels are added to the first oxide coating. The source of the secondary element(s) is at least one of: i) a soluble salt of the secondary element(s) in the electrolyte; ii) an enrichment of the surface of the substrate metal with secondary element(s) prior to PEO processing; and iii) a suspension of the secondary element(s) or oxide(s) of the secondary element(s) applied to the oxide of the metal after this has been formed by the PEO process. | 10-30-2014 |
