RFI Screening Ltd., England, has selected Metallisation MK61 Flamespray equipment from Metallisation Ltd., England, to metal spray a 40-metric-ton generator rotor with fine silver. It was first sprayed with a 25-micron coating of molybdenum, to optimize the adhesion of the top coat of silver. A final coating of silver was then added to achieve the specified outside diameter on the shaft. In a typical application, a coating 250 microns thick of silver would be sprayed.
Sensing element made via MIM for auto engines wins Grand Prize at PowderMet 2013
Indo-US MIM Tec Pvt. Ltd., Bangalore, India, earned a grand prize at PowderMet 2013 in the automotive engine category for a sensing element, a threaded port, and a support ring made for Sensata Technologies Holland B.V., Almelo, the Netherlands.

Diamond powders encapsulated in metal increase life of diamond compacts
Powdermet Inc., Euclid, Ohio, offers DiaBond, a family of engineered diamond powders specially designed to improve bonding in metallic matrices, including nickel-, cobalt-, copper-, and aluminum-based binders. DiaBond powders are comprised of diamond grains encapsulated in a 1-20 micron coating of cobalt, nickel, chromium, chromium carbide, tungsten, tungsten carbide, copper, aluminum, silicon, or rhenium.
Gold nanoparticles in polyurethane have high conductance and flexibility
Engineers at the University of Michigan, Ann Arbor, report that networks of spherical gold nanoparticles embedded in polyurethane elastic materials may make the best stretchy conductors yet. The team discovered that the gold nanoparticles align into chain form, making excellent conductive pathways, when the polyurethane is stretched. Flexible electronics have a wide variety of possibilities, from bendable displays and batteries to medical implants that move with the body.
