Are HVOF and Bimetallic Screw Barrels the Best Choice?
As it has been now quite evident that bimetallic liner, clasing and casting is a novel coating solution to extend the operational life of standard nitriding threaded barrel."bimetallic screw barrel" These coatings not only increase the strength of the end application but also provide protection to the internal components from possible corrosive effects. These coatings are usually manufactured in multiple layers and most often, they are coated with an ultra-light protective layer. This layer can be comprised up by over 20 different types of alloys, mostly High Performance Alloys or Superalloy, below are given the list and details about these various materials. In brief, we will see different types of materials for manufacturing a barrel assembly that has a nitrided surface.
Among the popular types of bimetallic coating is full encapsulation."bimetallic screw barrel" "bimetallic screw barrel" This kind of coating is usually employed to avoid corrosion between two different materials that are exposed to the same atmospheric conditions or environment. These alloys have a great attraction for the manufacturers because they do not allow the corrosion of other metallic surfaces that might otherwise occur. This in turn helps in preventing the premature failure of a barrel due to corrosion. This in turn protects the investments made by the users.
Full encapsulation bimetallic claddings are usually prepared by either low-pressure or high-pressure dielectric heat treatment."bimetallic screw barrel" "bimetallic screw barrel" In low pressure method, a very hard fine crystalline powder is used as a substitute for metallurgical bonding alloy. After this hardening process, a very hard, extremely wear-resistant and yet flexible metallic layer is formed on the surface of the hard material. This coating is called the ppa or the pearlscence coating. This coating provides the user with a great hard wearing and very useful metal that does not need any other maintenance procedures.
HVOF coatings on the other hand, provide an even higher degree of hardness than the ordinary metal screw."bimetallic screw barrel" "bimetallic screw barrel" The reason behind this is that HVOF coatings have more resistance to abrasions or scratches. If you were to use ordinary metal screws that are exposed to high-velocity or impact, the metallic component of these screws would surely be eroded away soon. In contrast, if we apply the topcoat of HVOF on the surface of the screws, the component's resistance to erosion and scratches will last for a longer time.
It is important to understand that both the processes discussed above have similarities."bimetallic screw barrel" They both offer excellent resistance to abrasions and scratches and a great degree of hardness as well. Nevertheless, there is actually no reason why HVOF should be considered superior to Bimetallic screw barrels. It is in fact the best choice when we consider factors such as price, durability and service.
Screws can certainly protect your machinery from any possible damage that might occur over a long period of time. However, if you need them to also offer optimal resistance to the wear and tear, you should definitely go for barrels. If you want to add to the protection that your equipment receives from dust, heat, grease, water and sand, you can simply add to its longevity by adding to its ceramic coating. There are many companies that manufacture and supply ceramic components to the manufacturing industry and you can find them by just making a simple online search.
