bridge or automobile are either painted or coated with zinc to prevent rusting.why aren’t they electroplating
Answers
Answer:
because electroplating is costly and it mostly helps in designing which is not needed...........
Answer:
Electroplating is a specific process in which a metal is deposited onto a conductive surface using electrolysis. It involves passing an electric current through a solution containing dissolved ions of the metal that is being plated, which causes the metal ions to be attracted to and deposited onto the surface of the object that is being plated.
While electroplating is an effective way to apply a layer of metal to a surface, it is not the only way to protect against rusting. Painting and coating with zinc are also effective methods of preventing rusting. In the case of zinc coating, a layer of zinc is applied to the surface of the object using a process such as hot-dip galvanizing or electro-galvanizing. Zinc is a sacrificial metal, which means that it corrodes preferentially to the iron or steel substrate it is protecting. As a result, even if the zinc coating is damaged or worn away, the underlying steel is still protected from rusting.
Painting and coating with zinc are often preferred over electroplating because they can be more cost-effective and easier to apply to large structures such as bridges or automobiles. Additionally, electroplating is generally used for decorative purposes or for precision applications where a specific thickness of metal is required, whereas painting and coating with zinc are primarily used for their anti-corrosive properties.
