Thin layers of metal are called metal coatings, and they are usually placed to the surface of another material for functional, ornamental, or protective reasons. They are employed in many different sectors, including electronics, medical devices, aerospace, and automobiles. Applying a thin layer of metal on the surface of another material is known as metal coating. This can be done for a number of purposes, including giving the underlying material a cosmetic surface, improving its electrical conductivity, or shielding it from corrosion.

A metallic coating is made up of a layer of corrosion-resistant protection that, by altering the surface characteristics of the material, can shield it from harsh external elements. Applications of metallic coatings on a surface include a variety of techniques.

Coatings made of a metallic element or metal alloy that are sprayed to surfaces chemically, electrochemically, or mechanically using a sprayer are referred to as protective metallic coatings. Such coatings are frequently used on equipment that has to be protected against sunlight, oxidation, and corrosion while yet having a glossy or shining look. Depending on the material being coated and the required qualities of the coating, different metal coating techniques will be employed for different applications.

The damage that metals sustain from chemical or electrochemical reactions with their surroundings is known as corrosion. The bulk of the material is lost as a result of metal corrosion. The physical and mechanical qualities of the material deteriorate as a result. Coating procedures offer financial advantages while safeguarding the chemical and physical characteristics of materials. Because iron and steel make up the majority of materials used in modern industry, the words corrosion and coating are crucial for steel. Corrosion is a key subject in these metals since iron and steel make up around 90% of the metallic materials utilized in industry today. The technique of applying zinc coating to iron and steel components derived from iron is known as galvanized coating. It is a part of industrial metal coating processes. Other than paint, it is the protective coating that is applied to ferrous metals the most. It is vital to decrease the coating's thickness in order to enhance its quality. As a result, expenses will go down.

A successful hot dip galvanizing process depends on a number of variables, including the angle at which the materials are immersed and removed from the zinc bath, the speed at which they are removed, the impact of using chemical solutions to clean the surfaces (acid-flux baths), and whether the materials are dried or wet after the flux bath. The zinc pool's temperature, the materials' surface roughness, and the duration of the materials' immersion in the zinc pool. The process variables influencing hot dip galvanized coating were reviewed in this review research using data from the literature.
