Flame-sprayed silver protects 40-ton generator rotor

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.

Wooden this be some skyscraper

For HSB Stockholm’s architectural competition 2023, three teams of architects produced innovative proposals for private residences of the future at three different locations in the center of Stockholm.   Berg | C.F. Møller Architects are working in partnership with architects Dinell Johansson and consultants Tyréns on their entry. The team chose to build upwards, and has designed a 34-story residential building, which will be seen for miles.

Timken to spin off engineered steels business

The Timken Co., Canton, Ohio, announces that its board of directors has approved a plan to pursue a separation of the company’s steel business from its bearings and power transmission business through a spinoff, creating two publicly traded companies.   A leading global manufacturer of carbon and alloy bar, producing ingot-cast and continuous-cast steel bars for the automotive, bearing, energy and industrial market segments, the separation is designed to improve performance in both companies.

Connecting the drops with 3D printing

Researchers from North Carolina State University, Raleigh, developed 3D printing technology and techniques to create free-standing structures made of liquid metal at room temperature.   “It’s difficult to create structures out of liquids, because liquids want to bead up. But we’ve found that a liquid metal alloy of gallium and indium reacts to the oxygen in the air at room temperature to form a ‘skin’ that allows the liquid metal structures to retain their shapes,” says Dr.

Grieve announces 550°F floor-level cabinet oven

Grieve Corp., Round Lake, Ill., announces the No. 1030 cabinet oven, a 550ºF floor-level electric cabinet oven, currently used for heating large gears at the customer’s facility.  Workspace dimensions of this oven measure 48 x 48 x 60 in. The 40 kW heating system is installed in Incoloy-sheathed tubular elements to heat the oven chamber, while a 2000 CFM, 2-HP recirculating blower provides horizontal airflow across the workload.   This oven features 6 in.

FW Gartner licenses technology for laser cladding of steel rolls from South Africa’s CSIR

FW Gartner Thermal Spraying, Houston, and South Africa’s Council for Scientific and Industrial Research (CSIR) have signed a licensing agreement on a laser cladding technology developed at CSIR.  The agreement follows the earlier development of a novel laser-based process for the cladding of steel processing rolls, a key component in steelmaking, CSIR said. The technology was tested and proven at ArcelorMittal’s Vanderbijlpark plant over the past five years.

Alfe helps design and heat-treat chassis and suspension for solar-powered car

Alfe Heat Treating, Fort Wayne, Ind., sponsor of the University of Texas Austin’s Solar Power Team, helped design and build the TexSun, a vehicle with an aluminum sub-frame and chassis. The 35-pound design is much lighter than the previous model’s 80-pound steel sub-frame and chassis. “The aluminum chassis was great because it is so much lighter,” said Alfe Vice President Dan Andersen.

Researchers explore the microworld using haptic optical tweezers

What if you could reach through a microscope to touch and feel the microscopic structures under the lens? In a breakthrough that may usher in a new era in the exploration of the worlds that are a million times smaller than human beings, researchers at Université Pierre et Marie Curie in France have unveiled a new technique that allows microscope users to manipulate samples using a technology known as “haptic optical tweezers.

Peacock-colored polymer is flexible and thin

A synthetic material that mimics the brightest and most vivid colors in nature and changes color when twisted or stretched was developed by researchers at the University of Cambridge, UK. It could have important applications in the security, textile, and sensing industries.   Instead of through pigments, these “polymer opals” get their color from their internal structure alone, resulting in pure color which does not run or fade.

Bubble lens bends light beams

Using a few tiny liquid bubbles to bend light beams could open the doors for next-generation, high-speed circuits and displays, according to new research at Penn State, State College. To combine the speed of optical communication with the portability of electronic circuitry, researchers use nanoplasmonics-devices that use short electromagnetic waves to modulate light on the nanometer scale, where conventional optics do not work.

Tata Steel opens French plant to heat treat 108-meter train rail

Tata Steel Europe, France, has built a new $16.5 million heat-treatment facility in Lorraine for the production of new harder-wearing 108-meter rail. An induction furnace heats the rails to 950°C, and compressed air then cools them quickly. The facility will allow the company to manufacture longer lengths of “super-hardened” rail for the first time.
