The smallest leaks are unacceptable with natural gas vehicles (NGV) fuel systems, so traditional leak testing approach is helium mass spectrometry.
New technique for probing subsurface electronic structure
“The interface is the device,” Nobel laureate Herbert Kroemer famously observed, referring to the remarkable properties to be found at the junctures where layers of different materials meet.
Nitrex turnkey systems enable nitriding/nitrocarburizing for Polish aerospace company
Nitrex Metal, St. Laurent, Quebec, reports that Polish aircraft engine and gear transmission manufacturer WSK “PZL- Kalisz” has started production on its new NXK-609 nitriding system from Nitrex Metal. The self-contained turnkey system, which has a diameter of 24 in. and a height of 36 in., nitrides gears and housings supplied to many world-leading aerospace firms. Nitriding with Nitreg technology meets the company’s requirement for precise control of the white layer thickness on Nitralloy parts, including zero white layer.
Hitachi VP-SEM offers four-axis motorized stage for smaller samples
The Nanotechnology Systems Division of Hitachi High Technologies America Inc., Clarksburg, Md., announces that its latest VP-SEM system, Model SU3500, is now available with a four-axis motorized stage, in addition to the existing five-axis motorized stage system. The new four-axis version is targeted for smaller sample applications (max. 200 mm in diameter and 70 mm in height).
Ipsen ships large aluminum brazing furnace to aerospace company
Ipsen, Cherry Valley, Ill., announces that it shipped a large vertical vacuum aluminum brazing furnace to a major aerospace company, a longstanding customer. This furnace, the customer’s second vertical furnace, will be installed in Mexico. Two other TurboTreaters will be shipped to Southeast Asia for the same aerospace company. One of these furnaces will be used for high-pressure gas quenching; the other includes AvaC for low-pressure vacuum carburizing.
