Abstract:Joining of Mo and MoSi2 with Mo and/or MoSi2 by brazing with nickel was studied. Molybdenum disilicide was prepared by the reaction of liquid silicon with the Mo substrate at the temperature of 1530 • C and 3 min. Wetting of both Mo substrate and MoSi2 was measured by sessile drop method; wetting angles were very low (close to zero). Products of interaction of Mo and/or MoSi2 with Ni were studied by electron microscopy with energy-dispersive spectroscopy (EDS) and X-ray diffraction methods (XRD). Shear strengt… Show more
“…High temperature plastic deformation under the applied stress is likely to be the origin of the joint formation. Although the joining of MoSi2 to metals is well-known [53][54][55][56], this work represents to the best of our knowledge the first report of a MoSi2 / MoSi2 joining without the use of metallic interlayers.…”
