YAKUT: DEVELOPMENT PROJECT FOR MANUFACTURING TECHNOLOGY FOR NICKEL ALLOY PLATING IN AVIATION

Metal Powder Laser Melting (LAM) process is a method of additive manufacturing, which is regarded as the manufacturing technology of the future, and the YAKUT Project aims to introduce this method to the defense industry in our country for functional part manufacturing from nickel super alloys. In general, additive manufacturing technology is based on the principle of part manufacturing by solidifying molten string, powder or sheet metal material as successive layers. It is regarded as the new industrial revolution of our time because of the advantages it provides such as a high level of freedom in design, weight and cost reduction.

 

Backed up by the Undersecretariat for Defense Industries (UDI), the YAKUT Project aims at acquisition of the Metal Powder Laser Melting (LAM) process as well as the process modeling capability for manufacturing of functional parts that have advanced mechanical features and can operate under challenging conditions such as high pressure and temperature differences in aircraft engines. Accordingly, under the project, the combustor component of the TJ90 turbojet engines, which consists of 9 sub-components, will be manufactured from UNS N06625 nickel super alloy material in one piece by using additive manufacturing method in a way to meet the mechanical requirements.

 

Through  the know-how and experience to be gained with the YAKUT Project, it is aimed for TEI to become a main engine manufacturer that is capable of manufacturing parts by using additive manufacturing methods in its own engines in the long term.
