Reducing Environmental Friction with High-Performance Coatings


By Jeff Elliott


hancing operational performance and ex- tending the life of parts across countless manufacturing and industrial sectors. Less understood is the value that these


S


coatings provide in reducing the environmen- tal impact of the industrial processes where they are used. It starts with one of the pri- mary reasons to use PVD coatings in the first place, which is to reduce friction between mated parts to improve performance. This can result in direct energy savings and, by extension, reduced carbon dioxide emissions. Because these coatings extend the life of com- ponent parts that require frequent replace- ment, the raw materials, metals and energy that are required to manufacture a replace- ment part, are also saved. In fact, some specialized coatings man-


ufacturers are making a strong case that coatings are a significant contributor to im- proving the environment. They not only point to these environmental benefits, but also to the enhancements they have made in their own coating equipment to operate more efficiently. In addition, continued advancements in specialized PVD coatings are also playing an


PACVD coated tooling can far outlast the lifetime of non-coated equipment.


Reducing Friction with Coatings Reducing friction when mated compo-


nents are in contact with each other is criti- cal, particularly in punishing environments where there are high loads and high wear.


pecialized physical vapor deposition (PVD) coatings are widely recognized for the critical role they perform in en-


important role in the design of components for new and emerging green technologies.


Bearings, gears, rollers and other precision components suffer from excessive wear, sur- face fatigue, pitting, galling and corrosion which can also cause failure especially in high-load applications. To prevent these issues from occurring,


specialized PVD coatings are applied in thicknesses of typically only a few microns to further harden the surface of these parts and through mechanisms such as altering the surface chemistry they can also lower the co- efficient of friction. As a result, less energy is used and less emissions are generated. Carbon-based coatings such as diamond-


Like carbon coatings (DLC) from specialized coatings formulators like Oerlikon Balzers, are even more durable. Produced mainly through Plasma-assisted chemical vapor deposition (PACVD), these well-adhering coatings provide a unique combination of high hardness and low friction coefficients. Such coated components are utilized for


a variety of applications that include wind turbine shaft bearings and planetary gears, stainless steel cutting blades and piston pumps, and sliding components across many industries. The coatings are also a proven technique for upgrading critical rotating
