When it comes to maintaining a great image for your product in the minds of the consumer one important factor to be kept in mind at the production level is that of longevity. Most products nowadays compromise essentially on finish and quality in a bid to keep costs low. One of the simplest and most hassle free ways to ensure your product serves the consumer for years in an environment friendly manner is to employ Physical Vapor Deposition(PVD) coatings on your products. |
The primary benefactors of the PVD technology are products in the metal families that require long lasting finishes and sustained durability. These can include fixtures in bathrooms, tools in applications where there was a high risk of wear and tear making durability an issue like in mining, automotive etc., lighting fixtures and many other surfaces. PVD is in essence a process wherein high temperature vaporization is used in a vacuum to coat products by converting a metal into vapor and magnetically or electrically charged environments are generated to attract the vapor to the metal surface that is to be coated. This brings the vapor into a solid form and creates a very thin yet durable film coating on the entire surface of the product.

Physical vapor deposition involves three basic categories for the achievement of the coating on the material, i.e. evaporation, ion plating and the sputtering method. There is also a variety of choices that can be made in the metal that is to be used for coating the product. Popular choices are titanium which produces a dark gold coating, zirconium which leads to a light gold coating, chromium which gives a silvery or chrome like coating. The introduction of further gasses can be used to manipulate the color of the coating.
The affordability and advantages of physical vapor deposition based coatings are manifold. It is especially advantageous over more primitive methods like electroplating and resorting to painting techniques because PVD coating does not require that you have large setups like plating baths which generate huge amounts of toxic waste and create the problem of toxic waste disposal. The process of PVD is far more environment friendly. PVD coating also tend to make the products harder and more corrosion resistant.
While initially physical vapor deposition techniques were evolved and were primarily used with regards to metals for high durability environments, over the years massive developments have ensures that the costs for PVD coatings have gone down significantly and also that developments in the coating processes have made it possible to even coat polymers and softer materials with high durability metal coatings to give them great finishes.
The basis of choosing what manner of PVD coating is best for the product is determined by a number of factors like the type of material that has to be coated, the cost of the coating, the abundance of the coating and the limitations that come inherent with the qualities of the material to be coated.
