Electroplate laminated structure and methods of fabricating the same

A corrosion-resistant laminated structure comprising:

• an object;
• a first layer formed on the object, the first layer having a first thickness;
• and
• a second layer formed on the first layer, the second layer having a second thickness,
• wherein the first layer and the second layer are formed by applying a first electric current and a second electric current, respectively, to the object placed in an electroplating solution, a first current density associated with the first electric current being different from a second current density associated the second electric current, and
• wherein each of the first layer and the second layer includes, at least in part, phosphorus.

A method of fabricating a laminated structure, the method comprising:

• providing an object in an electroplating solution;
• forming a first layer on the object by applying a first electric current having a first current density;
• forming a second layer on the first layer by applying a second electric current having a second current density;
• and
• forming a third layer on the second layer by applying a second electric current having the first current density,
• wherein each of the first layer, the second layer, and the third layer includes, at least in part, phosphorus.
