Plasma-sprayed aluminum-titanium coating to protect U.K. aircraft carrier deck
February 4, 2017
Source:
The Aircraft Carrier Alliance, U.K., reports that a plasma spray aluminum-titanium coating has been developed by British companies specifically to protect the flight deck of the new Queen Elizabeth Class aircraft carriers from the heat that results from the immense thrust of the engines of its F-35B Lightning II fighter jets.
The specialized thermal spray coating is being applied to sections of the vast flight deck of HMS Queen Elizabeth using a specially developed robotic spray that fires powdered metal through a jet of plasma at temperatures of almost 18,000°F. The molten droplets then flatten and quickly solidify, creating a tough but rough coating 2 to 2.5 mm thick that is bonded to the steel beneath. Approximately 2000 square meters of the 19,000 square-meter flight deck will be coated, with the work due to be completed prior to sea trials in early 2017.
The coating is made of a combination of aluminum and titanium powders, and can withstand temperatures of up to 2700°F. Developed in partnership with Monitor Coatings, based in Tyne and Wear, the material is expected to provide long-term protection through the 50-year life of the carriers. It is an important part of the work underway to prepare HMS Queen Elizabeth for sea trials this year and flight trials in 2018.
The QE Class ships, which include the Queen Elizabeth and the Prince of Wales, will each provide eight acres of sovereign territory to be deployed around the world. They will be versatile enough to be used for operations ranging from supporting war efforts to providing humanitarian aid and disaster relief.
According to Captain Simon Petitt, Senior Naval Officer of HMS Queen Elizabeth, "The new flight deck coating is one of the many 21st Century engineering innovations being incorporated in the Queen Elizabeth Class program. As the largest warships ever built for the Royal Navy, these powerful ambassadors will protect U.K. interests around the globe for the next 50 years."
The Aircraft Carrier Alliance has four members, three of which are industrial: Babcock, BAE Systems, and Thales UK. The fourth, the UK Ministry of Defence, has a dual role, acting as a member of the Alliance as the customer.
While both aircraft carriers will enter service under the white ensign of the Royal Navy, they will ultimately be utilized by all three sectors of the UK Armed Forces.

Additive manufacturing survey shows growth in Defense, Aircraft, and Space
February 3, 2017
Source:
Defence IQ, London, recently conducted a wide-ranging survey of additive manufacturing in the defense, aerospace, and space industries to explore what has changed in the last 12 months and what the future holds. The findings are summarized in an infographic that shows much more than the section shown here. This section refers only to answers to the question, "Which companies are the leaders in applying additive manufacturing?"
The graph compares the results of the 2015 survey to the results of the 2016 survey. The outcome displayed here shows that GE Aviation has moved firmly into the lead at 63%. Last year's leader Airbus, at 53% in 2015, fell to 40% in 2016.
One section of the infographic shows that 37% of respondents think that international bodies should lead additive manufacturing certification efforts, down from last year's survey. The trend for 2017 shows that more people think it should be led by cross-sector working groups.
Other sections of the survey ask what are the industry's biggest challenges, how many stakeholders are aware of the benefits of AM, and how many respondents think that AM will be "standard and ubiquitous" over the next years and decades.

Wisconsin Oven ships batch oven to Flame Treating to temper steel parts
January 30, 2017
Source:
Wisconsin Oven Corp., East Troy, Wis., has shipped a natural gas-fired draw batch oven to Flame Treating Systems Inc. in Durham, N.C., for tempering various steel parts. Flame Treating provides customized flame hardening systems to customers, and also provides in-house flame hardening services. The addition of this tempering oven allows the company to efficiently temper parts in-house.
The tempering oven has a maximum temperature of 1250°F and basket dimensions of 4x3x4 feet. Steel parts are loaded into the draw batch oven in the basket on two stainless steel pier rails with the load capacity of 2000 pounds gross. The recirculation system features a combination air flow arrangement that utilizes a 7000 CFM @ 10 HP plug-mounted blower. The combination airflow arrangement provides both horizontal and vertical upward airflow, which maximizes heating rates and temperature uniformity of the product.
"We are starting to do a significant amount of flame hardening for customers in our shop now," says Mark Sirrine, President of Flame Treating Systems Inc. , "so we needed a better solution than sending parts out for tempering. We installed the oven in the warehouse room adjacent to our 2000-lb. capacity spin flame hardening machine. Five days later it was in production, tempering batches of 800-pound sprockets. That pretty much tells you what you need to know about the ease of installation. We're looking forward to continuing to expand our services in the mid-Atlantic region for both localized hardening and tempering."

Can-Eng Furnaces Intl. Ltd., Niagara Falls, Ontario, has been contracted to design, manufacture, and commission an automated T7 Heat Treatment System for the processing of high-integrity aluminum automotive structural castings for a company in the European Union. The Can-Eng design was chosen for this new facility because it offers inherent part handling features that reduce floor space requirements and energy consumption, while providing predictable mechanical properties and dimensional stability of the castings.
The high-volume continuous line includes integrated handling systems connected to up/down stream processes. The T-7 system integrates a robotic handling solution furnace with Precision Air Quench (PAQ) technology, an artificial aging system, and controls integrating Level II SCADA system. The PAQ system integrates a unique combination of features that have been developed through continuous system improvements and modeling carried out in over twenty similar systems commissioned in recent years.
The PAQ system uniformly delivers controlled quenching processes that provide repeatable and uniform mechanical properties and accurate dimensional results. The system is scheduled to be delivered and commissioned to the EU in the third quarter of 2017.

Wallwork Group, U.K., announces that the scope of Rolls Royce approvals for the Bury (Manchester) site of metal thermal processing specialists Wallwork Group, has been extended to include the company's new vacuum brazing facility. Wallwork already undertakes aerospace work for Rolls Royce and it is hoped the new vacuum brazing unit with attract even more high-value contracts.
"Bury is the largest of our three UK sites and already has extensive approvals for metal heat treatment processes," explains sales manager Howard Maher. "Vacuum brazing is a relatively new addition to the services at this location and is a natural addition to the other high vacuum processes that we operate. Achieving Rolls Royce approval so soon after commissioning the new vacuum brazing development laboratory and assembly area is another feather in our cap." Bury is the lead aerospace processing site in the Wallwork group and already has extensive approvals for mainstream heat treatments such as case hardening, carburizing, hardening and tempering, nitriding, and many other common processes. In addition to further Rolls Royce approval, the company also carries approvals from other aerospace primes, such as BAe Systems, Airbus, Safran, Bombardier, Moog and many others, for specific heat treatment processes.
