Vacuum Metallizing to Enhance Quality

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. Metalizing processes include treatment, coating as well as combining an object with a metal. Thermal metallization involves where a heated substance is sprayed on the surface of another substance. Metalation involves reacting two substances where one is a metal that has carbon in it forming an organometallic compound with another organic compound. 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.

During the vacuum metalizing process, the metal to be used in the coating is heated in a vacuum chamber to its boiling point until it vaporizes. After vaporization, condensation follows and the metal particles settle on the surface of the object forming a metal 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. Metal rusting is reducing when objects are coated through the vacuum metallizing process since they highly durable object produced do not contact and absorb water and moisture. Vacuum metalizing is also an environmentally friendly process reducing the amount of carbon released into the atmosphere.

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.
