Abstract

Herein, with strong physical barrier of Ti₃C₂T_x MXene and ion-exchange ability of Zn-Al layer double hydroxide (LDH), MXene/LDH composite coating is designed on Al alloy to investigate the corrosion behaviors in dry/humid and temperature alternating environments. As a result, after alternating tests over 30 cycles, the MXene composite coating still possesses high corrosion resistance with a low corrosion current density of 4.86 × 10⁻⁸ A/cm² in 3.5 wt% NaCl solution. Similarly, the coating exhibits stable corrosion resistance under temperature alternating environments. It is attributed to the impermeability and oxidation of MXene as well as the Cl^- adsorption/trapping ability of Zn-Al LDH during the alternating cycles.

铝合金表面MXene/Zn-Al LDH涂层在干湿交变环境下的耐蚀性增强

利用Ti3C2Tx MXene的强物理屏障和Zn-Al层双氢氧化物（LDH）的离子交换能力，在铝合金表面设计了MXene/LDH复合涂层，研究了MXene/LDH在干湿和温度交替环境中的腐蚀行为。结果表明，在3.5 wt% NaCl溶液中，经过30多个循环的交替试验，MXene复合涂层仍然具有较高的耐蚀性，腐蚀电流密度为4.86 × 10−8 a /cm2。同样，涂层在温度变化的环境下也表现出稳定的耐腐蚀性。这是由于交替循环过程中MXene的不渗透性和氧化性以及Zn-Al LDH对Cl-的吸附/捕获能力。
