Patent ID: 11072866

Abstract:
An electroplated article includes a base member that includes one or more base member-metallic elements; and an electroplated layer that is formed directly on the base member. The electroplated layer includes at least a first electroplated layer-metallic element and a second electroplated layer-metallic element that is different from the first electroplated layer-metallic element. The second electroplated layer-metallic element is a metallic element that is identical to at least one of the one or more base member-metallic elements. A ratio of the second electroplated layer-metallic element in the electroplated layer is continuously decreased as being away from the base member in the thickness direction of the electroplated layer. Alloy grains including at least the first and second electroplated layer-metallic elements are distributed in the electroplated layer such that a clear interface is not formed between the base member and the electroplated layer.
