Abstract :

In this research, the process of TLP joint for super alloy FSX-414 by using the interface layer of MBF-100 as ribbon or powder have been studied. For this purpose, two samples of cobalt base alloy super clubs FSX-414 with dimensions of 10  mm for connecting sample with MBF ribbon & the other with the same dimensions with U&V shape track for connecting with powder have been done. In the following, both samples were subjected to a heat treatment cycle at temperature of 1175 degree of centigrade for 30 minutes’ microstructure of TLP connection area was investigated by using light microscope, scanning electronical microscope & EDS analysis, EDS map analysis & micro hardness. In microscopic pictures related to TLP bonding with ribbon & sample of powder of fuzzy areas, including the area under fuzzing & influenced area were specified completely. The result of EDS analysis & EDS map analysis & micro hardness of penetration capability& better connecting of ribbon rather than powder has been valided
