The electroplating technology of precious metal jewelry

Precious metal jewelry pieces after processing and molding, the color of its surface rendering is ecru. However, sometimes need to change the color of the surface, in order to achieve special effect. Such as requiring 18 K gold jewelry like pure golden, and 18 K white gold jewelry (white gold) is pure white like platinum wire, it is need to surface treatment, electroplating metal jewelry.

Electroplating is a complex process. It protect the jewelry metal surface, and can make the surface of metal jewelry more beautiful. Metal jewelry plating color plating and different color plating. Color plating is refers to the color of the plating color and jewelry metal base material is the same, jewelry metal base material and electroplating chemical composition also basically the same. Such as 18 k gold jewelry plating 18 k gold, 14 k gold jewelry plating 14 k gold. Different color refers to the color of the plating and electroplating composition and jewelry metal substrate has a different color and composition, such as 18 k gold jewelry plating 24 k gold ring white rhodium plated color. Electroplating is a kind of power in the form of lower solution method with the required coating process. Electroplating is the primary process for gold plating (for example) will need to be plated material immersed in metal salts (such as potassium cyanide gold) in the solution as the cathode. Gold metal plate as anode, connected to a dc power supply, on the need to be plated material will deposit the metal gold plating.
