Learn About the Physical Vapor Deposition Process (PVD)

Posted by Tribologix Inc on March 1st, 2017

PVD (Physical vapor deposition) can be described as a technique of coating an object with a film that is really thin. First of all, the material is vaporized at hand and the next step is to place it into an environment where low pressure is maintained. The condensation process coats it with a thin film of the substance. That is why it is known as physical vapor deposition. The most popular industrial coatings applied by PVD are titanium aluminum nitride, chromium nitride, zirconium nitride and titanium nitride.    

Even coating and minimal maintenance

The most important benefit of PVD film is that the coating process is even and you do not have to bother about some areas getting denser than other places. The entire area achieves even coating in the most effective way.  Another benefit is that the method is extremely clean and there is no need for any high maintenance.

Different methods employed

The most popular methods of PVD are being done with active gases like oxygen, nitrogen and methane and, plasma bombarding is employed as well. Different types of methods are used to create the gas and using the plasma. The most common methods are manipulation of ions, plate making, alloying using lasers and spluttering as well. Vacuum method is also used to conduct PVD and in such a situation, you are directing the vapors through a vacuum environment.

Learn about sputtering methods

The PVD techniques have developed over the years all around the world. The techniques are identified based on the source of the gas utilized for sputtering. Sputtering using cylindrical magnetron method is employed some companies and some others make use of diode method. Other leading ways of sputtering are the planar method, electron beam and triode-based as well. All these techniques can be incorporated into three major categories based on the vacuum transmission, condensation method and source of emission.

Important factors that determine the cost

What is the most important aspect that determines the cost of PVD process? The equipment utilized for the vapor transportation through the vacuum environment decides the cost. Another important aspect that affects the cost is the rate of deposition. It can be said that with the introduction of sophisticated techniques, the cost of PVD processes has come down significantly,

Cost effective solution

Many industries where a hard coating is needed have been making use of this process. Other coating processes demand huge expenses and more time and energy is required as well.    When it comes to physical vapor disposition, the cost and time needed are much less and the quality of coating stands tall as well. All these aspects make PVD a popular choice for many industries all over the world.

If you need hard coating, you cannot find a better option that PVD. The most effective way to determine which PVD method goes well with your unique requirements is to compare the expenses involved with the equipment and you should also consider the overall environment and maintenance of the operating machines and the cleanliness of the whole process.
