Why Industrial Aren’t As Bad As You Think

Process of Vacuum Metallizing

Several processes are usually involved in the metallization process which includes coating, metallizing, thermal spraying, vacuum metallizing, vacuum deposition, and metalation. Coating in metallization is used in enhancing appearance, adhesion and resistance to corrosion, wear and scratches through covering the surface of the object with another substance. Treatment, coating and combination of an object with a metal are among the processes involved in metallizing. Thermal metallization involves where a heated substance is sprayed on the surface of another substance. A process, where organometallic compound which are metals having carbon atoms are reacted with organic compounds, is referred to as metalation. Another process involved in metallization is the vacuum deposition which takes place in a vacuum where a very thin layer of a substance is deposited on the surface of an object. In the process of vacuum metalizing, a coating of an object’s surface using a metal is usually done in a vacuum chamber.

Vacuum metalizing process is carried out in a vacuum chamber where the metal used in the coating is heated to its boiling point where the metal forms vapour. Once the metal has vaporized, it is allowed to condense on the surface of the object to be coated forming a coating. Heating and vaporization of the metal uses heat generated in various processes including resistance heating and electron beam. In resistance heating, an electric current is usually passed through the metal and once it encounters resistance it heats the metal. Heating the metal using electron beams involves using cathode rays which emit negative electrodes in a vacuum tube producing heat. Vacuum metallization of objects is used to decorate the objects, protect the object from wear and tear and also to enhance the functions of that object such as increasing the conductivity of poor electrical conductor materials.

There are various benefits of vacuum metalizing. Vacuum metalizing always results into a uniform polish on the object with minimal effects on the health of the user. This is mostly for vacuum metalizing processes that use very harmful and poisonous metals and other substances to carry out the coating. Durable metals and other objects that last for a long period are also produced by vacuum metallizing where they cannot contact air and moisture which results into metal rusting. Vacuum metallization reduces the amount of carbon released into the atmosphere making the process environmental friendly.

Measures to prevent any damage on the object should be adopted to ensure that the market value of the object is maintained. Burned parts on the objects indicated by some parts lacking the shiny silver luster, distinct colors on the object as a result of the metal coating being too thin and appearance of rainbow colors on the object may lower the quality of the object. Such problems should be controlled enhancing the quality.
