The Role of Plating Additives
Author:Robby
Electroplating is prevalent in daily life, in electronic and electrical appliances, metal materials, automobiles, building materials, aerospace, agricultural processing, wear jewelry, etc. There is electroplating figure. Because of the production of electroplating. Metal products can be made corrosion-resistant. Plastic products are more durable. At the same time also make the appearance of these metal parts become more beautiful. It is also because the electroplating process has these excellent properties, in our surroundings, electroplating products everywhere.
The role of additives in the plating solution has two main ways: one, the formation of colloids adsorbed on the metal ions, hindering metal ions discharge, increasing the cathodic polarization; and two, adsorbed on the surface of the cathode, hindering metal ions in the cathodic discharge on the surface, or hinder the diffusion of discharged ions, affecting deposition of crystallization process, and improve the cathodic polarization. Additives can improve the plating organization, surface morphology, physical, chemical and mechanical properties.
