| 20090317656 | Aluminum alloy article with micro-arc oxide for film and method for making the same - An aluminum alloy article includes an aluminum alloy substrate and a micro-arc oxide film formed on the aluminum alloy substrate. The micro-arc oxide film includes a transition layer gradually infiltrating into the aluminum alloy substrate, a middle dense layer formed on the transition layer, and an outer dense layer formed on the middle dense layer, the outer dense layer having a density larger than that of the middle dense layer. | 12-24-2009 |
| 20090324840 | PROCESS FOR SEALING MICRO PORES OF MICRO-ARC OXIDE FILMS - A process for sealing micro pores of micro-arc oxide film is disclosed. The process comprises the following steps: providing a piece of metal formed with a micro-arc oxide film; blending a polyurethane resin and a firming agent to make a sealing agent; spraying the sealing agent onto the micro-arc oxide film to form a coating on the film's surface. The process can also be: blending an epoxy resin and a firming agent to make a sealing agent to sealing the micro pores by spraying. | 12-31-2009 |
| 20100040786 | PROCESS FOR SEALING MICRO PORES OF MICRO-ARC OXIDE FILMS - A process for sealing micro pores of micro-arc oxide film is disclosed in the present disclosure. The process may comprise the following steps: providing a piece of metal having a micro-arc oxide film; preparing a solution including ethyl silicate to make a sealing agent; dipping the metal in the sealing agent to form a coating on the film's surface. | 02-18-2010 |
| 20100040787 | PROCESS FOR SEALING MICRO PORES OF MICRO-ARC OXIDE FILMS - A process for sealing micro pores of micro-arc oxide film is disclosed in the present disclosure. The process may comprise the following steps: providing a metal coated with a micro-arc oxide film; blending a silicone resin and a diluting agent to make a sealing agent; daubing the sealing agent onto the micro-arc oxide film to form a coating on the film's surface. | 02-18-2010 |
| 20100040795 | PROCESS FOR SEALING MICRO PORES OF MICRO-ARC OXIDE FILMS - A process for sealing micro pores of micro-arc oxide film is disclosed in the present disclosure. The process may comprise the following steps: providing a metal coated with a micro-arc oxide film; providing a dipping solution including polyester methacrylate monomer for use as a sealing agent; and dipping the metal in the sealing agent to form a coating on the oxide film's surface. | 02-18-2010 |
