<div class='uawarticle'>There are situations when non metallic object need to have metallic properties for various reasons. The process by which such objects are coated with metal coatings to give them metallic properties is called metalizing. <A href="http://www.masterpowdercoating.com">Los Angeles metalizing</A> companies and experts have wide knowledge in coating a variety of substrates for various purposes. They can be hired to provide the services to a wide range of clients.<br />
<br />
Mirrors are among the earliest items to get metalized. Therefore, the process is almost as old as mirrors. Justus Liebig, the inventor of this process made the discovery in 1835. He was trying to coat glass with a layer of metallic silver when discovered the process. The application of the process became more popular when ABS plastics were introduced into the market.<br />
<br />
Non metallic items are normally poor conductors of both heat and electricity. This limits their ability to be plated, hence they must be made into conductors first before the process is done. Making non-metals into metals normally involves etching by use of chemicals. In this case, a mixture of chromic and sulfuric acid is the main chemical used. The object is dipped into the hot mixture for a given period of time to ensure maximum etching.<br />
<br />
Etching is followed by sensitization and activation of the object before proceeding to plating. The bond between the coating and the substrate is enhanced by coating the surface with electroless nickel or copper. Although the bond is strong, it is much weaker when compared to the bond formed when plating is done between a metal and another metal.<br />
<br />
The actual metalizing process takes place in a special chamber called a vacuum chamber. The coating metal and the substrate are both placed inside the chamber before the metal is heated to its boiling point. Heating is done through various methods such as resistance or plasma heating or by use of an electron beam. Once the boiling point is achieved, the metal is heated further until it vaporizes into fumes.<br />
<br />
The vaporized metallic fumes settle down onto the substrate to form a uniform coat over its surface. The resultant coating is normally very uniform and smooth. The thickness of the coating can be adjusted through the controls on the vacuum chamber. Leaving the substrate inside the chamber for a long period of time also allows the coating to grow thicker. The temperatures of non-metallic objects must however be maintained at reasonable levels at all times to prevent them from melting or getting disfigured.<br />
<br />
This process has several applications in industrial, commercial, and domestic settings. Some of the commonest applications include preventing corrosion, wear, and erosion. They can also be used as protection against high or low temperatures and electrical power on structural materials. The process is also very useful in changing electrical and aesthetic properties of objects. Plated objects appear different and more attractive due to the bright metals used.<br />
<br />
Various factors affect the price of the equipment used for metalizing. Some of the factors include capacity, quality, functions, and model. Some are small devices while others are the size of a room. Normally there are replacements for worn out parts.<br />
