Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for radiation shielding, and for other purposes. Jewelry typically uses plating to give a silver or gold finish.

电镀就是在首飾表面上电镀白金/金/玫瑰金。這種技術已经做了几百年。通常电镀被用来装饰物件，为抑制腐蚀，提高可焊性，硬化，以提高耐磨性，减少摩擦，以提高油漆粘附性，辐射屏蔽，以及用于其他目等等。通常珠寶首飾都會使用電镀白金或是金來保護首飾本身。
