If you live in an area close to the ocean, you will understand how just about everything corrodes quickly. Between the salt in the sea air and the harmful UV rays of the sun it is almost impossible to maintain any item without watching it slowly corrode. There is, however, a new scientific technique that can help preserve and restore the surface properties of various articles. This method is called high-velocity oxygen fuel. It is often abbreviated as HVOF, and it is well worth investigating.
HVOF, or high-velocity oxygen fuel, is a process where an item is coated by using a thermal spray. This thermal spray coating will restore or improve a component’s dimensions or surface properties. This will significantly increase wear resistance and erosion and extend the life of the equipment. Simply speaking, it will help the item to become corrosion protected. This will save a person, business, or an organization thousands of dollars in premature destruction of equipment or other important possessions. As mentioned, this will be especially true for items that are close to ocean shorelines.
The process includes spraying semi-molten or molten materials directly onto the surface of the product using a high-velocity gas stream and heat. This spraying technique will produce a very dense spray coating which later can be ground off to a very high-quality surface finish. When a person uses the high-velocity oxygen fuel coating technique, it will provide an exceptional hardness to alloys, metals, and ceramics. This method has proven to provide outstanding adhesion to these various substrate materials. It also has shown to provide substantial corrosion protection and wear resistance.
There is high velocity oxygen fuel technology specialists who can come to your company and offer an array of different spray coating materials that will suit your individual needs. Many of these unique companies are motivated by customer driven service and quality workmanship. They have facilities that can handle any component sizes to concrete and exacting standards with repeatable and reliable results.
This type of thermal spray coating technique is very attractive because it offers the customer an extensive choice of processes and materials. It also is a technique that is very environmentally friendly when you compare it to other conventional plating processes. High-velocity oxygen fuel coating techniques are similar to other thermal spray coating processes in that the material is heated and then accelerated by a gas stream that goes onto the component surface. This will help the part to attain better properties.
When the high-velocity oxygen fuel cooling process is used the gas stream that is produced results from an igniting and mixing of fuel and oxygen. This is done in a combination chamber which permits the high-pressure gas to speed up through a nozzle. The powder is introduced into this particular stream where it is accelerated and heated onto the component surface. This will result in thin overlapping platelets adhering to the surface of the part.
