Highlights To Know On HVOF Coating

By Harold Long


Corrosion and wearing is one of the biggest challenges that are faced by many when it comes to maintaining various surfaces. In this regard, the different methods that have been introduced have in one way or the other been able to solve this problem. Nonetheless, not all of these techniques are as effective and advantageous. Some are very expensive while others do not have lasting effects. In this case, it is very crucial for one to understand the benefits that come with HVOF coating.

For the sake of clarity, these are abbreviations that stand for high-velocity oxygen fuel. It is a concept of restructuring surfaces in order to prevent and reduce corrosion and wear. In this exercise, oxygen is mixed with other fuels, which could be in form of other gases or in liquid form. The mixture is then passed through a nozzle at high pressure and temperatures onto the affected surface.

The method is quite expensive. The cost that is incurred until its completion is quite huge. Before considering anything else, the cost of buying oxygen and the required fuels is very high. These are not substances that are readily available in the market, which means getting them is not a walk in the park.

Additionally, the method is done purely by special machines. Mixing gases and fuels is not a thing that one can do manually. The equipment needed is of high value and can cost a lot, whether buying new ones or fabricating them. The mixture is sprayed on the surface using a spray gun. This machine is not cheap either.

This means that chances of corrosion are greatly reduced by this coating. So many technicians prefer to use this process on surfaces since its effects are well visible. Its also important to note that it is not a very complicated process. Almost all the work is done by the use of machines. Nonetheless, the individual must understand how to mix the gas and the fuels in the right quantities.

Once this covering is done on a certain surface, the end results are very exquisite. They include improved performance, added hardness and increased resistance for wear and corrosion of the surface. However, depending on how the covering is done, the time it takes to be replaced or to be redone is different.

It is also a process that has long term effects when it comes to wear and corrosion resistance. This is the main reason why this process has become so preferable in the current world. Due to this effect, the lifespan and effectiveness of the surfaces is improved greatly.

Generally, its unpleasant to have surfaces that are corroded and worn out. In this regard, it is very vital to consider processes that will reduce or eradicate these conditions. One of the best methods is use of HVOF covering.
