On November 2, Powderloop Technology announced its participation in the European Space Agency (ESA) "Prepare for Space" program, collaborating with TWI Ltd, Cosmic Bridge, and Bearingline to bring its in-situ alloying powder production technology and hardfacing coating powders into aerospace applications. Headquartered in Braintree, UK, the company said the collaboration focuses on enhancing the resilience and sustainability of the aerospace materials supply chain.
Powderloop's in-situ alloying technology generates micron-scale carbides directly within the melt pool during additive manufacturing. The uniformly distributed carbide precipitates improve hardness, fracture toughness, and corrosion resistance. Its spherical, free-flowing powders are produced by agglomerating fine elemental powders with master alloy particles into composite granules. The material systems cover refractory metals (tungsten, tantalum, niobium, titanium), hardmetals (tungsten carbide), and cermets (titanium carbide). Among these, the cobalt-free tungsten-titanium-based multi-carbide powder is currently at TRL 3/4. Under the planned division of work, ESA will provide targeted market analysis, use-case definition, and commercial opportunity mapping; TWI will conduct feasibility validation of coating deposition using selected powders; and Bearingline will subsequently provide commercialization support. Powderloop aims to complete coated test coupons and components within the program framework.
The program explicitly identifies additive manufacturing and advanced thermal spray coatings as aerospace application directions. Powderloop's agglomeration-based powder route can cover high-melting-point refractory metal systems that are difficult to process via atomization, offering a process alternative for tungsten, tantalum, niobium, and titanium powders. Its cobalt-free carbide solution addresses the demand for cobalt-free composite powders in aerospace hardfacing coating scenarios. The ESA program will help drive these powders into the European aerospace supply chain. The agglomeration route covers high-melting-point refractory metal systems that atomization struggles to handle, providing an alternative process path for tungsten, tantalum, niobium, and titanium powders, and ESA backing will accelerate the entry of such powders into the European aerospace supply chain.
