The invention relates to the technical field of molten salt electrolysis, and particularly discloses a nickel-iron-based alloy coating as well as a preparation method and application thereof. The nickel-iron-based alloy coating comprises the following raw material components in percentage by mass: 30%-56.8% of Ni, 8%-25% of Cr, 5%-10% of Al, 0.1%-2% of Si and the balance of Fe. The nickel-iron-based alloy coating is prepared through a plasma cladding method and a high-temperature oxidation method, metallurgical bonding of a cladding layer and a base body is achieved, an oxidation film layer formed through high-temperature oxidation is compact in structure, the high-temperature oxidation resistance, the high-temperature molten salt corrosion resistance and the high-temperature conductivity of an anode material can be effectively improved, and the anode preparation cost is greatly reduced. 本发明涉及熔盐电解技术领域，具体公开一种镍铁基合金涂层及其制备方法与应用。所述镍铁基合金涂层按质量百分比计，包括如下原料组分：Ni：30％～56.8％，Cr：8％～25％，Al：5％～10％，Si：0.1％～2％，余量为Fe。本发明采用等离子熔覆
