Determinants of the quality of brazed joints of nickel-based superalloys
Journal Title: UNKNOWN - Year 2017, Vol 16, Issue 3
Abstract
In the aerospace industry, passenger safety depends on proper quality control at each production stage. The main responsibility for the correct operation of the aircraft lies within a gas turbine. A proper and rigorous selection of the gas turbine construction material is required, and in a further step, the method of joining the construction parts. Nickel superalloys due to the high heat resistance, strength and creep resistance at high temperatures, toughness and corrosion resistance, are very often used for the construction of a gas turbine engine. In the next step, the selection of joining method is necessary. This method must be able to achieve high-quality connections, resistant to work at high temperatures and corrosive environments. The most effective bonding method that meets the above conditions is brazing. In this study non-destructive (visual) test and destructive (metallographic) test of brazed joint of Inconel 718 and Inconel 625 were conducted.<br/><br/>
