    摘要:

    利用真空電弧熔煉技術(shù)與急速冷卻快淬設(shè)備制備了一種等原子比AlNiZrCuY高熵非晶復(fù)合材料薄帶，利用X射線衍射儀（XRD）、掃描電子顯微鏡（SEM）、差示掃描量熱儀（DSC）、顯微硬度計(jì)等手段表征了該復(fù)合材料的顯微結(jié)構(gòu)、相穩(wěn)定性并測(cè)定其硬度；通過極化曲線和電化學(xué)阻抗譜等測(cè)試方法研究了高熵非晶復(fù)合材料室溫下在模擬海水（3.5 wt.% NaCl水溶液）中的防腐蝕性能。結(jié)果表明：Al20Ni20Zr20Cu20Y20高熵非晶復(fù)合材料是由非晶態(tài)組織與金屬間化合物相共同組成；利用阿基米德排水法測(cè)得材料實(shí)際密度約為5.792 g/cm3；其維氏顯微硬度為461 HV0.1，擊破電位(Eb)為-0.215 V，維鈍電流密度( ipass)為29.44 μA/cm2。該高熵非晶復(fù)合材料在金屬表面防腐與耐磨領(lǐng)域應(yīng)用前景廣闊。

    Abstract:

    A new kind of equiatomic AlNiZrCuY high entropy amorphous composite material (denoted as HEACM) ribbons was prepared by vacuum arc melting technology and rapid quenching system. The microstructure and phase stability of HEACM were characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM) and differential scanning calorimetry (DSC), and the hardness was measured by Vickers microhardness test methods. All tests were performed in simulated seawater (3.5 wt.% NaCl corrosive solution) at room temperature by CHI660E electrochemical workstation. The corrosion resistance of Al20Ni20Zr20Cu20Y20 was investigated by potentiodynamic polarization curve (Tafel) and electrochemical impedance spectroscopy (EIS). The results show that Al20Ni20Zr20Cu20Y20 HEACM is composed of amorphous phase and intermetallic compounds. The actual density measured by Archimedes method is about 5.792 g/cm3. The Vickers microhardness of this composite material is 461 HV0.1. Its breakdown potential (Eb) is -0.215 V and maintaining passivity current density (ipass) is 29.44 μA/cm2. The equiatomic AlNiZrCuY high entropy amorphous composite material has broad application prospect in the field of corrosion resistance and wear resistance on metal surface.
