What is the difference between galvanizing and electroplating

This alloy is quite hard. Damage is not caused to the coating by the usual abrasion, even though some damage may take place to the pure soft zinc present at the top.

Electro galvanization produces Zn layer on surface that is termed to be not continuous with that of steel metallurgically. Electro-galvanization has very low life, ranging from several months to some years only. But, hot dip galvanization is known to have very high life averaging between 20 to 50 years. Electro-galvanization comes with excellent finish.

However, hot dip galvanization has dull, unpleasant finish. The coating thickness entirely depends upon the dipping duration. Electroplating is the process of coating a metal with a thin layer of another metal by electrolysis to improve the metal's corrosion resistance.

The metals most commonly used in plating are: Copper. Hot-dip galvanizing is a process of applying a protective zinc coating by dipping product in bath of molten zinc. Zinc plating or electroplating is a process where zinc is applied by using a current of electricity.

It is a thinner coating than hot-dip galvanizing making it unsuitable for outdoor applications. Galvanisation is when a protective zinc coating is applied to steel or iron, to prevent rusting. This is when metal parts are fully submerged in a bath of molten zinc. Zinc plating also known as electro-galvanising is a process where zinc is applied by using a current of electricity.

While the HDG is plain, and not so eye-catching. Another difference is the thickness of both finish, this is the difference youneed to measure with professional equipment.

Ans: Galvanization: The process of coating Zinc layer on substances made copper or steel or other metals, which gets corrosion when exposed moist air for long time is called galvanization.

Using galvanization process prevention of corrosion is possible on the metal surface. Ex: Iron Bridge can be protected from rusting by galvanizing the iron using zinc protects.

Electroplating: It is the most common application of the chemical effect of electric current is electroplating. Electroplating is done in industries to have an anti-reactive coating on the parts of machines so that they do not react with the raw material, to have an anti-corrosive coating for the machines so that they do not get corroded, and a heat-resistive coating for parts like boilers to resist the heat produced by the machinery.

Gold plating is one of the most common applications of electroplating in ornament-making. In electroplating, the solution gets dissociated into its respective ions. The positive ions are called cations, and the negative ions are called anions. Is there a dark color plating process that does not add much thickness yet still is conductive so "paint-free" areas are not required. What is the thickness added in black zinc plating?

Hi Jonathan. It will probably be conductive enough for safety grounding, but certainly not conductive enough for digital signals. All information presented is for general reference and does not represent a professional opinion nor the policy of an author's employer.
