Abstract: Upon a substrate subsequent layers of elastic ink are jetted using an ink jet printing system. Each layer is immobilised by a immobilisation step before jetting the following layer. A printing relief is gradually formed to obtain a flexographic printing plate allowing accurate control over the relief and slopes of the printing plates. Use can be made of different inks or immobilisation step to obtain different layer characteristics. Inks can be immobilised using UV curing. The recorded relief of the layers can be measured and corrections can be applied using a feed-back loop. A rejuvenation process for printing plates can be constructed using the described method. An elastic base layer can be provided on the substrate to provide better plate characteristics.

Abstract: A process for protecting a thermal barrier coating (TBC) on a component used in a high-temperature environment, such as the hot section of a gas turbine engine. The process applies a protective film on the surface of the TBC to resist infiltration of contaminants such as CMAS that can melt and infiltrate the TBC to cause spallation. The process generally entails applying to the TBC surface a metal composition containing at least one metal whose oxide resists infiltration of CMAS into the TBC. The metal composition is applied so as to form a metal film on the TBC surface and optionally to infiltrate porosity within the TBC beneath its surface. The metal composition is then converted to form an oxide film, with at least a portion of the oxide film forming a surface deposit on the TBC surface.

Abstract: In order to achieve micro alloying of protective coatings for components such as turbine blades in a turbine engine, a base metal is splutter coated by deposition of a trace element to a desired proportion. A protective layer of the base metal is then applied over the trace element to prevent further reaction or oxidation of the trace elements. A coating consumable is therefore formed from the base metal and the trace element. The consumable may be produced immediately prior to coating of the component or may be inertly stored for subsequent use. The consumable is applied by laser deposition techniques whereby a coating is formed in the melting process.

Abstract: A method of fabricating silicon-on-insulators (SOIs) having a thin, but uniform buried oxide region beneath a Si-containing over-layer is provided. The SOI structures are fabricated by first modifying a surface of a Si-containing substrate to contain a large concentration of vacancies or voids. Next, a Si-containing layer is typically, but not always, formed atop the substrate and then oxygen ions are implanted into the structure utilizing a low-oxygen dose. The structure is then annealed to convert the implanted oxygen ions into a thin, but uniform thermal buried oxide region.

Abstract: An apparatus and method is disclosed for orienting the magnetic anisotropy of longitudinal patterned magnetic recording media. A disk-shaped longitudinal granular magnetic recording medium is provided having a high orientation ratio in the circumferential direction. The medium is then patterned to form a uniform array of magnetic islands. The magnetic islands are then irradiated with ions to increase the magnetic exchange coupling between the grains of each island. This aligns the axes of magnetic anisotropy of the individual grains with the average axis of magnetic anisotropy of the grains, thereby aligning the magnetic anisotropy of each island along the circumferential direction.

Abstract: A hole in a sample from which a sample piece has been extracted with a focused ion beam is filled at high speed using ion beam gas assisted deposition. A method of filling the hole by using the ion beam includes a step of irradiating the hole formed in a face of the sample with the ion beam to thereby form an ion beam gas-assisted deposition layer in the hole. The ion beam gas-assisted deposition layer is formed in the hole while controlling the area to which the ion beam is irradiated so as to cause the ion beam to fall on a part of a side wall of the hole and to not fall on another part of the side wall in an area scanned with the ion beam. The filled hole may then be covered with a protective film.
