The difference between electroplating and gold plating:
April 26,2022
Different Definitions
Electroplating: Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. Metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. The outer layers of many coins are also electroplated.
Gold plating: Gold plating is a decorative craft and one of the commonly used words. Originally it refers to a thin layer of gold plated on the surface of the utensils. Later, it is also used as a metaphor for people to go to a certain environment to further study or exercise just to gain a false reputation.
Different Effects
Electroplating: The technology of depositing a metal coating with good adhesion but different performance and base material on mechanical products using the principle of electrolytic cell. The electroplating layer is more uniform than the hot-dip layer, and is generally thinner, ranging from several microns to tens of microns. By electroplating, decorative protective and various functional surface layers can be obtained on mechanical products, and workpieces that are worn and machined incorrectly can also be repaired.
Gold plating: The gold-plated layer has good ductility, easy polishing, high temperature resistance, and good discoloration resistance. Gold plating on the silver layer can prevent the discoloration of silver; gold alloy plating can present a variety of tones, so it is often used as a decorative plating, such as plated jewelry, watch parts, artwork, etc.
Different Types
Electroplating: Electroplating is divided into rack plating, barrel plating, continuous plating and brush plating, which are mainly related to the size and batch of the parts to be plated. Rack plating is used for products of the same size, such as car bumpers, bicycle handlebars, etc.Barrel plating is suitable for small parts, fasteners, washers, pins, etc. Continuously suitable for partial plating or repair. The electroplating solution includes acid, alkaline and acid and neutral solutions with chromium compound. No matter what kind of plating method is used, the plating tank and hanger that are in contact with the product to be plated and the plating solution should have a certain degree of generality.
Gold plating: Gold plating is divided into two categories, one is gold plating of homogeneous materials, and the other is gold plating of heterogeneous materials.
Homogeneous material gold plating refers to the gold plating of the surface of gold jewelry. Its significance is to improve the brightness and color of jewelry.
Gold plating of heterogeneous materials refers to the gold plating on the surface of non-gold materials, such as silver gold plating and copper gold plating. Its meaning is to replace the color of the plated material with the luster of gold, so as to improve the appreciation effect of jewelry.
