The Benefits if Using PVD Finishing

If we compare the quality of tools in the past couple of decades we shall notice that there is a general increase in the availability and affordability of higher quality tools and more damage resistant tools. Of course this is a result of technological advancement but it is important to understand that advancement too. This strengthening and also in a way the availability of more colorful tools is a result of the adoption of Physical Vapor Deposition (PVD)in the industrial structure.

The technology of physical vapor deposition has been around for a long time and has mostly been used in the applications related to areas which incur large amounts of damage in their equipments like those of aerospace technologies, excavation and mining technology and areas of high stress with minor uses in homes for fixtures and appliances. Over the decades now this technology is being more readily accepted by more mainstream users in the production of watches and silicon industries. However the cost involved is one drawback to the benefits of PVD.

The process itself of PVD involves placing the substrate that is to be coated in a vacuum where a solid material is then introduced which under high amounts of pressure is subjected to vaporization. This vapor is then treated and transported to the substrate where it is attracted to it by means of magnetic or electric charge. This vapor settles on the substrate creating a fine finish which is the completed process.

There are various methods that can be used to give the substrate a finish and these involve evaporation, ion plating and spluttering. The various methods are dependent on the type of material and other factors. The finish that is the result of the PVD process is very helpful in reducing friction and stopping the material of the substrate from becoming oxidized over time. The color of the end finish is largely dependent on the material used and the gasses used for the reaction.

A great benefit of using the Physical Vapor Deposition technique is that it has a comparatively minute footprint on the environment and has no toxicity in terms of waste produced like older methods of electroplating and methods which involved dealing with paints. Technically PVD is also more efficient in giving the substrate a heightened resistance to damage and wear and tear which results in more uptime for the equipment. Subjecting equipment to PVD ensures that there is significantly less wear and tear over time and that expensive equipment last longer and runs more efficiently.

Another advantage of PVD is that it is now not only limited to hard metallic instruments. Developments in the field have made it possible for softer metals and even polymer based products to be put through this process and ensure that the same level of hardened strength and durability is also made available to these products.

PVD is a top of the line solution for ensuring that resistance is provided to valuable equipment and existing equipment is made damage resistant. To read more about the benefits of using PVD finishes for different products, click here.
