Metallizing is the general name for the technique of coating metal on the surface of objects. Metallic coatings may be decorative, protective or functional. Metallic coatings may be decorative, protective or functional.
Metallizing (also metalize) to coat, treat, or combine with a metal. Thermal spraying melted (or heated) materials are sprayed onto a surface. Vacuum deposition is a family of processes used to deposit layers as thin as one atom to millimeters thick in a vacuum. Vacuum metallizing the metallic coating of an object takes place in a vacuum chamber.
Another example of early chemical coloring of metals is the Nebra sky disk, which has a green patina and gold inlays. An early example of black colored iron is the famous Celtic spearhead found in the River Thames and dated between 200 and 50 BC. [4] [5]
An example is a microwave popcorn bag. Many food items are also packaged using metallised films for appearance only, as these produce a package with greater sparkle when compared to competing products that use printed paper or polymer films.
Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
Silvering aims to produce a non-crystalline coating of amorphous metal (metallic glass), with no visible artifacts from grain boundaries. The most common methods in current use are electroplating, chemical "wet process" deposition, and vacuum deposition.
Alonizing is a diffusion metallizing process in that it is a thermochemical treatment that involves enriching the surface layer of an object with one or more metallic elements. [1] Specifically, alonizing is the diffusion of aluminum into the surface of a base metal through high temperature vapors. [ 2 ]
Granulated Etruscan earring, 4th century B.C. Granulation is a jewellery manufacturing technique whereby a surface is covered in spherules or granules of precious metal. The technique is thought to have its origins in Sumer about 5,000 years ago.
