Electrodeposited platinum-gold alloy
| DWPI Title: Article used for metal alloy coatings, comprise film of platinum-gold alloy coated onto a substrate, where alloy is composed of platinum, alloy has a microstructure composed of generally ellipsoidal grains, microstructure of alloy encompasses multiple of nanopores |
| Abstract: A coating made of platinum-gold alloy is provided, together with a method of its preparation by electrodeposition. The alloy is composed of more than 50 atomic percent platinum. The microstructure of the alloy consists of generally ellipsoidal grains. More than half of the grains have a major axis of 10 nm or less. |
| Use: Article used for metal alloy coatings. |
| Advantage: The article has maintained strength, ductility, wear resistance, hardness, and fracture resistance and high thermomechanical nanocrystalline stability. |
| Novelty: An article comprises a film of platinum-gold alloy coated onto a substrate, where the alloy is composed of more than 50 atomic percent platinum, the alloy has a microstructure composed of generally ellipsoidal grains, and more than half of the generally ellipsoidal grains have a major axis of 10 nm or less. |
