Method of forming amorphous metal coatings on steel workpieces

A method for forming a coating on a steel workpiece, comprising:

• 1) performing an etching treatment to the steel workpiece to obtain an etched steel workpiece;
• 2) performing an electropolishing treatment to the etched steel workpiece by using the etched steel workpiece as an anode to obtain an electropolished steel workpiece;
• 3) performing a plasma treatment to the electropolished steel workpiece to obtain a plasma treated steel workpiece;
• 4) depositing an intermediate layer on the surface of the plasma treated steel workpiece to obtain a steel workpiece with the intermediate layer;
• and
• 5) depositing an amorphous metal coating on the steel workpiece with the intermediate layer, wherein the amorphous metal coating is comprised of an amorphous alloy selected from the group consisting of:
• a zirconium-based amorphous alloy, a copper-based amorphous alloy, a nickel-based amorphous alloy, an aluminum-based amorphous alloy, a titanium-based amorphous alloy, an iron-based amorphous alloy, or a palladium-based amorphous alloy.
