RUAG Australia achieves international patent for additive metal technology solution

RUAG Australia has been awarded full patent rights in Australia, Europe and the United States for its “Methods for Treating Aircraft Structures”. This patent relates to the use of Supersonic Particle Deposition (SPD) as an alternative aircraft component repair technology to save the time and costs associated with traditional repair techniques or part replacement. SPD repair capabilities significantly improve aircraft and component return-to-service times....

RUAG Australia’s patent application identifies the use of the additive metal technology, Supersonic Particle Deposition (SPD), as a fully certifiable alternative for safe and reliable repairs. According to the patent, SPD is an ideal method for rapidly repairing corroded, worn and damaged components as opposed to repair by traditional methods or outright component replacement. Potential cost and time savings make this solution particularly relevant for the repair of expensive components and for components with long repair/replacement lead times.  

“The awarding of this patent underscores our commitment to research and development and the application of emerging technologies to offer reliable and accessible service for commercial aviation customers,” states Neil Matthews, Senior Manager of Advanced Technology and Engineering Solutions, RUAG Australia.

Australian, European and US patents for “Methods for Treating Aircraft Structures” were awarded in May, October and November 2018, respectively. RUAG has also submitted an application for another patent featuring the use of SPD technology, “Methods for Restoring an Aircraft Frame Element”, which is currently under review.

RUAG Australia is a major industry research center for the development and application of Powder Deposition Technologies focusing on both SPD, sometimes referred to as Cold Spray, and Laser Assisted Deposition (LAD) for defense applications. These technologies offer a number of exciting and cost-effective outcomes, particularly in the areas of geometry restoration and corrosion protection. In addition, these technologies enable the restoration of corroded / damaged metallic components / structures to an acceptable level of structural integrity and functionality. RUAG Australia maintains and operates a fixed and mobile SPD capability as well as a fixed LAD capability.
