The plated steel material is a plated steel material including a steel material and a plating layer provided on the surface of the steel material, wherein the plating layer has a predetermined average chemical composition, when the amount of Mg is % Mg and the amount of Al is % Al, % Mg/% Al is 0.80 or more, and a metal structure in a total field of view of 25,000 m.sup.2 in a vertical cross section which is a cross section in a thickness direction of the plating layer includes 10 to 40 area % of a MgZn.sub.2 phase, 10 to 30 area % of an AlZn phase with a Zn content of 10% or more, 0 to 15 area % of an Al phase with a Zn content of less than 10%, and 25 area % or more of an Al/MgZn.sub.2/Zn ternary eutectic structure.

A method of chemical deposition of Iridium oxide film on rigid substrate is provided. The method comprises providing a rigid substrate in a container, adding an iridium precursor and mixing the iridium precursor with water to form an iridium precursor liquid in the container, adding and mixing an oxidant with the iridium precursor liquid in the container; and depositing an iridium oxide film on the rigid substrate in the container. A chelating agent and pH adjustor can be either selectively used for stabilizing the chemical bath deposition and for adjusting pH value of the liquid. For a variety of rigid substrates to be applied, the pH adjustor can adjust the pH value within a range of 413. By employing the proposed fabrication method, it is extraordinarily advantageous of chemical alkaline as well as chemical acid deposition formula with configuration of depositing sodium-doped IrO.sub.x iridium oxide film.

A plated steel material includes a plated layer containing, by wt %: 0.5 to 14% of Al, 0.5 to 5% of Mg, and the balance being Zn and inevitable impurities. The plated steel material satisfies the following Equation: ([Mg].sub.S[Mg].sub.1/2)/[Mg].sub.1/20.3. [Mg].sub.S means a content (wt %) of Mg in a surface of the plated layer, and [Mg].sub.1/2 means a content (wt %) of Mg at a t position (t represents a thickness of the plated layer) from the surface of the plated layer in a thickness direction.
