Abstract
The paper examines how the Ni–Zr–Cr alloy wets (Ti, Cr)B2, AlN, (Ti, Cr)B2–AlN, and AlN–(TiB2–TiSi2) refractory materials. The wetting of (Ti, Cr)B2 leads to near-zero contact angles. The introduction of AlN additions deteriorates wetting of the refractory materials by the nickel alloy, and the Ni–Zr–Cr alloy does not wet pure aluminum nitride. There is insignificant diffusion of Zr to (Ti, Cr)B2 in contact of the alloy with the refractory materials. There is no interaction in the AlN–(Ni–Zr–Cr) system. The composite materials are promising for use in contact with high-temperature corrosive alloys.
