Gold Plating Technique
The common gold plating process was as follows: ** 1. Electroplating process ** 1. ** Deconstruction and cleaning ** - Alkaline washing: Use an alkaline solution such as a solution of soda to remove organic matter such as grease. - Acid washing: use sulfuric acid, sulfuric acid and other acid cleaners to remove the metal surface of the rust layer and rust. - Washing with water: removing the residue after the alkali-washing and acid washing. 2. ** Undercoat ** - selecting Ni, copper, and the like as the plating base material, using the object to be plated as the negative pole, Ni or copper as the positive pole, and dissolving the positive pole through the current in the bath to form a plating base layer on the surface of the object to be plated. The methods of plating the base layer include plating, chemical plating, and the like. 3. ** Gold Plating ** - Metal gold was used as the material, and the metal gold of the positive pole was dissolved and plated on the negative pole (the object that had been plated) through the current in the bath. The thickness of the gold plated layer could be adjusted from a few millimeters to dozens of millimeters according to the needs. 4. ** Electrolyte adjustment ** - The composition and process conditions of the Electrolyte were adjusted. The commonly used Electrolyte components were acidic cyanide-based Electrolyte and alkali-based Electrolyte to ensure that the coating was uniform, smooth, and stable. 5. ** Post-processing ** - Washing: Remove any remaining liquids. - Neutralization: Neutralize acidic and acidic residue. - Dry: Remove moisture. - [Polishing: Makes the gold-plated layer brighter and smoother.] ** 2. Electroless Gold Plating Technique ** - The product that needed to be gold-plated was placed into the gold-plating solution. The melted gold atoms reacted with the chemical to form a gold-plated layer on the product. The chemical gold-plating did not require a direct power supply. ** 3. Other gold-plating process examples ** 1. ** Copper and Brass Gilding ** - Using organic liquids to remove oil: Use gasoline or carbon dioxide to remove the oily stains on the electronic components. - Supersonic chemical oil removal: This step is carried out after the oil removal with organic solution is completed. - Washing: Hot water, cold water, acid washing (a mixture of sulfuric acid, nitric acid, and water), and soaking in a solution of soda. - Gold plating: Use a gold plating solution that contains gold potassium cyanide and potash to carry out gold plating. - Washing and drying: Wash with ultrasonic agitation in purified water at 70 - 80 ° C (the electrical conductivity of purified water should be less than 10us/cm) for no less than 10 minutes, and finally dry. 2. ** Phosphor Bronze Gilding ** - Gasoline to remove oil stains: First, use gasoline to remove the oil stains on the electronic components. - [Supersonic chemical oil removal: This step will be carried out later.] - Washing and acid washing: hot water, cold water, and acid washing. - Gold Plating: Use a gold-plating solution containing gold potassium cyanide and potash to plate gold. 3. ** Gold-plated process of special golden finger lead wire (a special case)** - The processing of the printed circuit board (PC) was to form a connection module with broken gold-plated leads on the outer circuit. - "Ink resistance printing: Print a carbon ink resistance between the connecting modules at both ends, and use the carbon ink resistance to conduct the connecting modules at both ends. - Gold-plated: Use the connection module and carbon ink resistance to gold-plate the predetermined gold-plated pad position of the printed circuit board to complete the production of the golden finger. There were the following steps to recover and refine the gold-plated waste: - To prepare the gold removal powder, add the gold removal powder into hot water, stir it to accelerate the dissolution, and let it settle. - Gold removal: The electronic waste was added to the gold removal water, and the agitation accelerated the gold removal. - Acid adjustment: After removing the gold, add lemon acid to adjust the acid. Stir to accelerate the dissolution and test the acid. - "Substitute oxidization: Add in the zinc-wire, and after two hours of substitution, it will be oxided. Then, add in the solute to start the oxidization. - Impurity removal: such as adding impurity removal agent, heating to remove impurities, cleaning sponge gold, etc. In addition, there was another gold-plating process, which was three spraying and two baking, that is, spraying the primer → drying → spraying the reaction layer → spraying the topcoat → drying.

The usage of gilding and gold-plating
Gold gilding and gold-plating were essentially the same process. The first step was to prepare the gold amalgam. First, the gold had to be thinned and cut into pieces, then placed into a pre-heated crucible, and then injected with mercury. The ratio of gold to mercury was 1:5 - 1:7, so that it was mixed into a paste. During this process, the surface of the object needed to be cleaned with an acid and base solution. Then, it was time to apply the gold. The gold amalgam was evenly applied to the surface of the object (such as bronze). Next was to crack the gold. By baking the plated object, the mercury would evaporate and the gold would remain on the surface of the object. Finally, it was calendering to make the coating more dense and bright. When the operation was done, the color of the coating could remain unchanged for a long time. This kind of craft could be used to decorate building components such as copper and iron and various utensils. In ancient times, apart from being used on the surface of utensils, it was also used to gild weapons. The entire process usually needed to be repeated about three times, but to achieve a better gilding effect, it was common to repeat it five to seven times.

Low Reflectivity of Vacuum Plating in ShenZhen
There may be the following reasons that affect the low reflective rate of vacuum plating: 1. ** The background vacuum of the vacuum coating chamber **: It not only affects the film's cohesion, but also the reaction with the reaction gas during the evaporating process. The other residual gases will be vaporized and decomposed under the effect of high temperature and electric field, affecting the purity of the reaction gas, thus polluting the surface of the vacuum coating and reducing the reflection rate of the vacuum coating. 2. ** Bias voltage **: For the vacuum coating decorative film, the bias voltage is generally selected to be 0 - 30 volts. If the bias voltage is too high, reverse splashing will occur, which will affect the deposit rate and affect the luster of the vacuum coating layer, which may affect the reflection rate. 3. ** Purity of plated metal and reaction gas **: If the purity of plated metal or reaction gas is not enough, the reflection rate may be reduced. 4. ** Evasion rate **: If a low rate is chosen to sufficiently react the reaction gas with the evaporated film material particles in the reaction vapor plating process, it may affect the performance of the film, such as the reflective film. A low rate may lead to a decrease in the reflective rate. 5. ** The combination of the film and the film layer **: There may be harmful impurities attached to the surface of the film during the processing and cleaning process, such as water vapor, oil and gas, cleaning liquid, wiping liquid, polishing powder, etc. The impurities that go deep into the damage layer are difficult to remove with ordinary methods. When the film material molecules accumulate on these impurities, it will affect the film layer attachment and may reduce the reflection rate. In addition, if the films had poor water affinity, poor absorption power, or poor chemical stability, the surfaces of the films would be corroded to form a corrosion layer or a decomposition layer during the pre-processing process, which would affect the absorption of the film layer and thus affect the reflection rate. 6. ** Film stress **: There will be stress during the film formation process. The stress of each layer of the multi-layered film is different. The existence of stress is harmful to the film strength and may affect the optical properties of the film, including the reflection rate. For example, the stress may cause the film to crack or form a network of fine channels, thereby reducing the reflection rate. 7. ** Film structure related to the surface hardness of the outer layer **: For example, the anti-reflective film is generally made of MGF2, and its film profile is a loose cylindrical structure, which may affect the optical properties such as surface hardness and indirectly affect the reflection rate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
