Metal in its pure form is not so pleasing to look at. In order to use it in the manufacture of commercial and residential equipment, a layer of coat is usually applied on its surface to improve its look or protect it from the agents of corrosion. Typical coating processes include electroplating, chemical vapor deposition, and physical vapor deposition. However, the latest and most effective coating technique is referred to as High Velocity Oxygen Fuel or HVOF.
Unlike the traditional coating techniques that have been in use over the years, the use of HVOF promises to increase both erosion and wear resistance as well as to significantly protect the coated surface against corrosion. But what is HVOF exactly? Well, this is a coating process that is applied to materials that require their surface properties to be maintained when subjected to the destructive elements of nature.
Thus HVOF, like any other coating process before it, is essentially used to extend the life of certain materials. This process works by spraying, onto the surface of interest, semi-molten materials at very high temperatures and at a very high velocity. The result of this is a dense spray coating that can be ground to very high surface finish. For more information the best HVOF Solutions, visit National Alloy Solutions Yelp Page
The good thing about HVOF coating is that it allows the application of coating materials such as alloys, metals, and ceramics to generate an exceptional coating that among other things has an outstanding adhesion to the substrate material. The process also achieves commendable corrosion protection and wears resistance. HVOF is an attractive coating technique since it offers a wide choice of materials and processes that have no negative impacts to the environment.
As you would expect of any thermal coating technique, HVOF powder materials are pre-heated and accelerated by a stream of gas to the surface of interest. This gas is obtained by mixing and igniting oxygen with a suitable fuel. This is done in a combustion chamber where the high-pressure gas can be accelerated through the nozzle. The outcome mainly consists of thin overlapping platelets that offer the surface enhancements required
