Title:
BORIDE-REINFORCED ALUMINUM-CONTAINING HIGH-ENTROPY ALLOY COMPOSITION
Document Type and Number:
Japanese Patent JP2023133141
Kind Code:
A
Abstract:
To provide a boride-reinforced aluminum-containing high-entropy alloy composition.SOLUTION: A composition, a machine component (29, 50) coated with the composition, and a method of coating the machine component (29, 50) are provided. The composition includes a CoNiCrAlY alloy, where three or more elements of the CoNiCrAlY alloy are present in equimolar amounts, one of the three or more elements of the CoNiCrAlY alloy being aluminum (Al), and where a molar fraction of Al is between about 0.20 and about 0.25. The composition further includes a transition metal boride including at least one of: cobalt boride (Co2B), titanium boride (TiB2), zirconium boride (ZrB2), tantalum boride (TaB2), niobium boride (NiB2), or molybdenum boride (Mo2B), and a high-melting point alloy.SELECTED DRAWING: Figure 1
