Outline of Research at the Start

ハイエントロピー合金(HEA)は、高強度、優れた耐食性、高温安定性や電磁気特性を示し、合金種の創製や機能性発見に多角に研究されている。一方、省資源、軽量化の薄膜合金の作製は、現行の定電圧制御電析法では薄膜中の各種元素含有量の制御が困難である。本研究では、無水塩有機溶媒浴液中での単元素の電析電位や多元素の共析挙動を調査し、優れた耐食性と耐摩耗性をもつHEA薄膜をマルチパルス電析法によって創製する。

Outline of Final Research Achievements

The chlorides of Cr, Mn, Fe, Co, and Ni were dissolved in an organic solvent of DMF-CH3CN, in which either constant potential or pulsed potentials were applied on a copper substrate to get electrodeposited thin films. As a result, high-entropy alloy films containing Cr, Mn, Fe, Co, and Ni were obtained on the substrate as long as the applied potential was less noble than -2.0V vs. SSE. The film has an amorphous structure containing some nanocrystals, with complete oxide/hydroxide for Cr and Mn, near all oxide/hydroxide for Fe, half oxide/hydroxide for Co, and little oxide/hydroxide for Ni. The film showed similar hardness, wear resistance, and corrosion resistance with the copper substrate. High electrocatalytic activity in the oxygen evolution reaction was obtained.

Academic Significance and Societal Importance of the Research Achievements

本研究では、Cr、Mn、Fe、CoまたはNi等の塩化物を有機溶媒に溶かして各種金属元素の電析条件を明確にし、さらに多元素間の共析挙動を解明したことで、ハイエントロピー合金薄膜の電析法による創製に可能性を提供した。今後、元素組合せに無数の合金薄膜の作製が簡単になり、合金開発や材料作成に省資源や軽量化等の目標を達成できる。将来、薄膜合金に秘めた表面機能のみならず、優れたバルク機能をもつ合金の開発も加速できる。
