    This article presents our the results of the part of the European AWFORS Project related to single crystal blade repairing by laser cladding. First, we present the overview of the project and the aims related to single crystal blades. Thus, physical metallurgy considerations are presented. These elements related to the process modeling is followed by a process parameter search. The materials used are both single crystal superalloys CMSX2 and MC2. Once the parameters are...

    The pitting corrosion resistance of Alloys 625, C-276, 59, and 686, in the laser clad condition, was characterized by using ASTM G28 and ASTM G150 test protocols. Test samples were examined using light and scanning electron microscopy. Alloys 59 and 686 are wrought alloys designed to be exceptionally pit resistant. Test results of laser clad samples show th...

    Presented at ICALEO 2005

    Refractory intermetallic compound Nb3Al is expected as a candidate for structural materials operated at much higher temperatures compared to conventional Ni superalloys. However, Nb3Al is difficult to fabricate by conventional methods. Little work has been reported on synthesis of Nb-rich intermetallic alloys by laser deposition. This paper presents research work on laser deposition of a powder blend of Nb, Ti, Al pu...
