摘要： The present invention relates to the production of a bronze plated substrate having a golden appearance thanks to a multiple-layer plating method. The method notably comprises plating a substrate having at least one layer of copper with a tin layer which thickness represents 3.5 % to 12% of the copper layer thickness. The method further comprises annealing the plated substrate in an annealing furnace comprising a plurality of heating zones, the last heating zone of the furnace having an annealing temperature ranging from 600°C to 815°C. The annealing step of the method is performed under controlled operating parameters which comprise an annealing residence time, the annealing temperature and the relative thickness of the tin layer in view of the copper layer. The operating parameters are controlled in accordance to each other to ensure obtaining the gold-like appearance of the plated bronze.
摘要翻译：本发明涉及通过多层电镀法制造具有金色外观的青铜镀层基板。该方法特别包括将具有至少一层铜的衬底与厚度为铜层厚度的3.5％至12％的锡层电镀。该方法还包括在包括多个加热区的退火炉中对镀覆的基板进行退火，炉的最后一个加热区的退火温度范围为600℃至815℃。该方法的退火步骤在包含退火停留时间，退火温度和考虑到铜层的锡层的相对厚度的受控操作参数下进行。操作参数根据彼此控制，以确保获得镀金青铜的金色外观。
