Abstract

The development of materials resistant to wear and highly resistant to high-temperature salt corrosion is a pressing issue in ship gas turbine construction. In this case, use of the Ni(L)–Hf–Cr₃C₂ alloy, which contains hafnium 16.5–17.5 wt%, is promising. The addition of hafnium enables the formation of a structure maximum resembling the eutectic phase, with a melting point of 1200 + 10°C, maintaining stable hardness within the range of 649–665 HV₁₀ and exhibiting an average corrosion rate of 0.18 mg/(cm²×h) in a 5% Na₂SO₄ + 25% NaCl environment at 900°C. The results obtained allow us to recom­mend this alloy for use as a base material for reinforcing the contact surfaces of marine gas turbine engine components.
