Abstract: | The development of wear-resistant materials possessing high resistance to high-temperature salt corrosion is a pressing issue in ship gas turbine construction. The Ni(L)-Hf-Cr3C2 alloy, which contains hafnium from 16.5-17.5 wt%, is promising in this case. The addition of hafnium enables the formation of a structure maximum resembling the eutectic phase, with a melting point of 1200 + 10 degrees C, maintaining stable hardness within the range of 649-665 HV10 and exhibiting an average corrosion rate of 0.18 mg/(cm2 x h) in a 75% Na2SO4 + 25% NaCl environment at 900 degrees C. The results allow us to recommend this alloy as a base material for reinforcing the contact surfaces of marine gas turbine engine components. |
