Navy unveils breakthrough alternative to chromate-based corrosion inhibitor for DoD aircraft In 2009, the Department of Defense issued a mandate requiring the military departments to find new ways to reduce their use of hexavalent chromium, a carcinogen that became infamous in the eyes of the public after the release of the film "Erin Brockovich." Chromate-based corrosion inhibitors are widely recognized as the best inhibitors available. Now there is a powerful "as good as" alternative.

Engineer's Toolbox: How to choose the right relay Relays come in a variety of form factors, styles, and technologies. Depending on your application, only one relay type may be suitable. In other cases, multiple relay types may be appropriate. By understanding the strengths and weaknesses of the different relays, you should be able to pick the one that is best suited for the job at hand. National Instruments lays out the options.

Heavy-duty mini transmitter offers maximum customizability for OEMs Designed for heavy-duty use, Scanreco's Mini Transmitter is compact and easily customized to meet OEM and system integrator requirements. It communicates with the corresponding receiver using a Scanreco protocol and a unique identity code, which guarantees that no other transmitter can activate the machine unintentionally. The Mini Transmitter can accommodate one to six linear levers or one to three joysticks, as well as several push buttons and switches. Operator feedback is available via high-performance color display, monochrome display, or LEDs. The stop function conforms to performance level "d" (PL d) as specified in the EN ISO 13849-1 standard for safety-critical components of control systems.

Composites used as bearings and wear parts Did you know that composites can make excellent bearings and wear parts? These materials feature low friction and low wear and are self-lubricated, shock resistant, and electrically insulating. Starting with tough, chemically resistant, and proven resin systems, Norplex-Micarta's materials are specifically engineered to the requirements of a particular application. The ability to combine multiple materials allows for a wide range of performance demands to be met economically. Heat can be removed by adding metal wire, PTFE surface layers can promote improved break-in, aramid fibers can provide both excellent strength and low wear, and reinforcements can be chosen to minimize moisture absorption.
