What is claimed is: 1. A golf club head, comprising: a substrate including at least one of a fibrous material, a foam, a ceramic, a metal, a metal alloy, a polymer, and a composite; and a structural coating coupled to the substrate and including an electrodeposited fine-grained binary Ni—Fe
What is claimed is: 1. A golf club head, comprising: a substrate including at least one of a fibrous material, a foam, a ceramic, a metal, a metal alloy, a polymer, and a composite; and a structural coating coupled to the substrate and including an electrodeposited fine-grained binary Ni—Fe alloy, the electrodeposited fine-grained metallic material having an average grain size that is in the range of 2 nm to 5000 nm, a yield strength that is in the range of 200 MPa to 2,750 MPa, and a hardness that is in the range of 100 Vickers to 2,000 Vickers, the structural coating having a thickness in the range of 30 μm to 5,000 μm, such that the electrodeposited fine-grained metallic material represents at least 10 percent of a total weight of the golf club head. 2. The golf club head claim 1, wherein the electrodeposited fine-grained material represents at least 10 percent of the total weight of the golf club head and up to 95 percent of the total weight of the golf club head. 3. The golf club head of claim 1, wherein the electrodeposited fine-grained metallic material represents at least 20 percent of the total weight of the golf club head and up to 95 percent of the total weight of the golf club head. 4. The golf club head of claim 1, wherein the substrate includes a metalized layer, and the electrodeposited fine-grained metallic material is adjacent to the metalized layer. 5. The golf club head of claim 1, wherein the yield strength of the electrodeposited fine-grained metallic material is in the range of 1,500 MPa to 2,750 MPa. 6. The golf club headof claim 1, wherein the hardness of the electrodeposited fine-grained metallic material is in the range of 500 Vickers to 1,000 Vickers. 7. The sports article of claim 1, wherein the electrodeposited fine-grained metallic material has an ultimate tensile strength that is in the range of 1,000 MPa to 2,000 MPa. 8. A golf club head, comprising: a portion including a first layer configured as a permanent substrate; and a second layer coupled to the first layer and having a thickness that is in the range of 30 μm to 5000 μm, the second layer representing at least 10 percent of a total weight of the portion and including a fine-grained binary Ni—Fe alloy, the fine-grained binary Ni—Fe alloy material having an average grain size that is in the range of 2 nm to 5000 nm. 9. The golf club head of claim 8, wherein the Ni—Fe includes about 80 percent by weight of Ni and about 20 percent by weight of Fe. 10. The golf club head of claim 8, wherein the first layer defines an internal compartment of the portion, and the second layer is a fine-grained inner coating adjacent to the first layer. 11. The golf club head of claim 8, wherein the average grain size of the fine-grained material is in the range of 2 nm to 750 nm. 12. The golf club head of claim 8, wherein the fine-grained metallic material has a modulus of resilience that is at least 0.25 MPa. 13. The golf club head of claim 8, wherein the fine-grained metallic material has an elastic limit that is at least 0.75 percent. 14. The golf club head of claim 8, wherein the fine-grained metallic material has a tensile strain-to-failure that is at least 3 percent. 15. The golf club head of claim 8, wherein the permanent substrate includes at least one of a fibrous material, a foam, a ceramic, a metal, a metal alloy, a polymer, and a composite, and the second layer is an electrodeposited coating coupled to the permanent substrate and including the fine-grained material. 16. The golf club head of claim 8, wherein the fine-grained metallic material has a yield strength that is in the range of 200 MPa to 2,750 MPa. 17. The golf club head of claim 16, wherein the fine-grained metallic material has a hardness that is in the range of 100 Vickers to 2,000 Vickers.
