However, it is difficult to manage the effects of this high number of parameters including their interaction effects. Here are 3 benefits of chemical effects of electric current. Some of these are detailed below: Copper plating of semiconductors: Various metal plating options are used in the electronics industry. The process uses an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode. Name two metals which are usually electroplated on cheaper metals for making jewellery (or ornaments). Electroplating occurs due to mass transport in the solution as a result of migration in electric field, diffusion in concentration gradient and convection in a flow field [30]. Uses of Electroplating. Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which batteries produce electric currents. Most common Kitchen appliances are Nikel plated. The most extensive use of gold plating is on jewellery and watch cases. What is Electroplating? Electroplating is based on (a) heating effect of electricity (b) chemical effect of electricity (c) physical effect of electricity (d) magnetic effect of electricity. As a result, electroplating is host to several defects due to the complexity of the process. What an Engineer or Designer Should Consider Before Electroplating. Solution: Electroplating consists of depositing a thin layer of metal on another metal, either to protect the surface from corrosion or for a decorative effect. Common electroplating defects often include issues that are present before plating, such as cold shuts, pitting, sharp edges, cleavage points and unclean manufacturing. 1. Question 8. effect of electrolyte current density and conductivity on electroplating thickness. There are many specific examples of electroplating applications across various industries. Add your answer and earn points. Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes. 17. Question 9. The lightning conductor used in building protects the building by : An electrolytic cell set up to electroplate a fork with a silver coating is shown in Figure 1. Name the most common application of the chemical effect of electric current. During plating, flaking or … 16. While the actual health effects of electroplating depend on the specific chemical, most of the health hazards are very serious 1.Acids are most often used for electroplating, and most of them result in lesions and burns when they touch the skin, according to the handbook 1.The solvents used to clean objects before plating can result in a light-headed feeling, headaches and even death. Effects. Chromium plating for bicycles and cars is also achieved using a similar method, but with a Chromium Salt electrolyte. Copper is (a) a good conductor (b) an insulator (c) both (a) and (b) (d) none of these. Nesting of parts during the electroplating process. The transport equation Solution: The most common examples of the chemical effect in electric currents are: Gold plating and chromium metal plating to prevent corrosion. Since electroplating involves both an electrical and a chemical reaction at the surface of the part, exposure to the plating chemistry is critical to the overall performance of the finished product. All these things are examples of electrochemistry: chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products. Nickel and chromium-coated articles are used in automobiles and household appliances. Question 1. Chemical effect c. magnetic effect 1 See answer jejejeevan is waiting for your help. Zinc coatings prevent the corrosion of steel articles. Electroplating parameters that can be listed as bath temperature, pH of the bath, current density, surfactant addition or type, coating thickness must be controlled during the deposition process since they determine the properties of the coating.
