Improved Corrosion Resistance in Aluminum Joints

Executive SummaryWhile aluminum and aluminum products are generally not subjects of corrosion due to environmental conditions, they are still subject to the effects of galvanic corrosion. By altering the nobility of aluminum, the effects of galvanic corrosion can be minimized and the durability of aluminum products may be enhanced. Description of TechnologyWith...

Enhance Processibility and Performance by Isomeric Mixing of Reactive Oligoimides

IntroductionThermosets or thermosetting resins are materials that irreversibly cure once they are cooled from their initial mixing temperature. Because they cannot return to a liquid state when reheated, thermosets are ideal for applications in which high temperatures are required. The process for making these materials is complex and requires a strict...

Composite Metal Matrix Castings and Solder Compositions and Methods for Microelectronics and Metal Matrix Castings

IntroductionThe rapid advance in the miniaturization of electronic components require novel soldering solutions with sub-micron reinforcements. Sub-micron reinforcements can minimize grain boundary sliding. Another challenge is increased current density in Micro-Electro-Mechanical Systems (MEMS). Ion migration across electrodes causes voids and ultimately...
