What is a spray system?

Spraying is the process of a thin film deposition in which a solid target material is fired to the surface of the substrate to form a thin coating. The spray system is a machine in which the spray process occurs. It contains the whole process and allows the user to adjust the materials of temperature, power, pressure, targets and substrate.

Spraying is known as the deposition of physical steam, because a thin film is created by physical means rather than chemical reactions. In the spray system, the vacuum chamber contains target material, energy source and gas plasma. The gas, which is usually a noble gas such as Argon, is brought to a very low pressure chamber to start the process. This causes gas to ionize and creates positive ions known as cations. These cations bombard the target material and knocking pieces that travel through the chamber and put on the substrate. The process is easily maintained in the spray system chamber because other electrons are exempt during the ionization of gas plasmy.

Spray systems differ in terms of structure, energy sources, size and price. The orientation of the target material and the substrate is specific to each machine. Some systems will face the target material parallel to the substrate surface, while the other leans one surface and creates a different deposition formula. For example, a confocal spray in a circle facing a focal point. The substrate in this type of system can then be rotated for more even deposition.

Power source also varies because some systems use direct current (DC), while others use the power of radiofrequency frequency (RF). One type of spraying system, known as Magnetron, also includes magnets for stabilizing free electrons and even thin film deposition. These methods give the spray system different properties of temperature and speed of deposition.

axle systems are movingIn size from table systems to large machines that are larger than the refrigerator. The inner chamber also differs in size, but is generally much smaller than the machine itself; Most chambers have diameters less than 1 yard (about 1 meter). The cost of the spray system ranges from less than $ 20,000 in US dollars (USD), up to $ 650,000 per new or custom -made system.
