In this study, the Inconel 625 alloy, which is widely used in the industry in nikel-based super alloys, was wrapped with 3 different piping powder. The wire powder used is 90 % elementary nano wire powder + 10 % NaBF4 (NB), 90 % nano hegzagonal wire nitrate powder + 10 % NaBF4 (h-NBN) and commercial EKabor 2 powder in micron size. Boiling process at 1000°C at 3 s. It was accomplished in time. After the welding process, the samples were submitted to optical microscope, microstability test and XRD analysis. In these studies, the effects of different chemical powder contents on the characteristics of the cover layer and phase formations have been studied. The results of the studies have been observed that pipe, silicide and nitrate layers were obtained depending on the chemical powder components. The obtaining of higher bor-containing pipe phases with nano-bor powder has shown that the purity degree of pipe powder is effective on the type of phases that will form. In this study, the formation of unwanted silicide layers in Ni-based super alloys was prevented by changing the chemical content of piping powder. In addition, as an alternative to the commercial ECabor-Ni tubing powder used in both Ni-based alloys, nano-bor and nano-hegzagonal bor nitride powder have been developed and developed with these powder compared to commercial bor powder (Ekabor 2, Ekabor-Ni and B4C) thicker cover layers have been obtained.
