Norsk Titanium G-IVL Rapid Plasma Deposition (RPD) machine (Installation of fast plasma deposition)

2019: Announcement of installation of fast plasma deposition

On June 17, 2019 the Norsk Titanium company (Norsk) announced that it designed and is engaged in assembly of larger installation of fast plasma deposition (Rapid Plasma Deposition, RPD). Installation allows to make larger and difficult components for aircrafts and engines with the increased print speed. The G-IVL RPD installation will use the same RPD technology on which process of additive manufacturing of Norsk company is based.

According to the company, the patent RPD technology and the equipment of Norsk company use proprietary management tools process for melting of a titanic wire in the argon environment by means of plasma torches for the purpose of production of components for the aviation constructions and engines having the profile close to set. The G-IVL installation of Norsk company will expand outline borders of printing to dimensions of 190 cm x 40 cm x 60 cm. It will print both bilateral, and one-sided components with difficult geometrical parameters and to besiege material with a speed more than 8 kg per hour. The components received as a result will have quality of material equivalent to forgings.

The G-IVL installation considerably will expand as possibilities of Norsk, as well as the target market of components capable to use RPD technology. It will reduce a ratio of the purchased and used material, will reduce the cost of machine processing and will reduce terms of accomplishment of orders. We used the same well-tried remedies of process control which underwent testing in applications for commercial aircrafts in this big installation. told Carl Johnson, the senior vice president for an engineering part and the chief technologist of Norsk

The RPD technology of Norsk company is the first-ever technology of direct power sedimentation (Direct Energy Deposition, DED) approved by Federal management of aircraft (FAA) that makes Norsk the qualified supplier of the structural titanic components made by an additive method for producers of the complete equipment emphasized in the company. Proprietary RPD - process of Norsk company is suitable for applications, structural and important in terms of security, in industrial segments of aircraft industry and aviation engines, oil and gas, sudo-, the car - and machine-tool construction. Norsk performs more than two years continued serial production of components for commercial aircrafts.

At the beginning of 2019 Society of automobile engineers (SAE) issued the technical specifications "Additive Material Specifications (AMS) 7004 and 7005" for RPD material and RPD process of Norsk company. It is the first process of direct power sedimentation (DED) for which the SAE specifications were issued.

Besides, Norsk for June, 2019 is the first and only additive producer which performs printing and testing of the rotating part of the aviation engine. It was made in partnership with Pratt Whitney, TurboCam and Turbomashinny laboratory of the Notre Dame University (UND). The rotor with the integrated blades (IBR) with a diameter more than 20 inches was printed, subjected to machining and checked for compliance to the same tough standards, as the compressor disks Pratt Whitney, and then tested on the speed limit of rotation in Turbomashinny laboratory UND.
