Thermal Spray- Various Applications And Uses Revealed

Today technology has advanced to a huge extent that there are some special type of coatings for buildings as well as for metal structures. These are applied by using different spraying methods.

A similar type of technique is there that’s called Thermal Spray. In this procedure a ceramic material, metal or alloy is melted and after that it is sprayed. The main purpose of all this is to add a layer on various things so as to change the surface properties of a substance. The extra added layer is generally termed as a coating.

Quite often this kind of technique is confused with brazing or welding. But in fact, this process differs from the two widely.

What are the common applications of Thermal Spray?

Let’s begin with some basic ones:

·         Wind turbines- These usually get damaged due to atmospheric conditions and for this reason, manufacturers use a special type of spray or coating in order to protect the turbines from any kind of corrosion because of the environmental conditions.

·         Bridges- The bridges tolerate a huge traffic on the daily basis and thus these need some effective metal spraying. It is helpful to extend the life of the structure. For this a roller spray system is used.

·         Petro Chemical Plants- In this area, a high maintenance budget is utilized just to control the corrosion rates. For protecting things from this spraying of metal is considered to be an ideal procedure for refineries, tanks and other steel made parts.

·         Oil industry- The structures like pipes and risers are often exposed to some of the harsh elements and conditions. So, it can be beneficial to apply the thermal sprayed material. It can protect things up to years.

·         LPG cylinders- Metal spraying is usually used in LPG and propane gas cylinders for protection. This is done by using arc spray procedure.

·         Architectural coatings- There are different parts like support columns, balcony decks, decorative windows, etc that are under corrosive effects of the environment. Thus use of thermal coatings can be an ideal solution to prevent the risks of distortion.

How to decide the type of material used for coatings?

Sometimes this technique of external coating is also known as Hardfacing and in order to decide the type of material that should be used, first the type of wear is very important to be understood.

The main types include abrasive and adhesive wear. The former consists of the lower impact conditions. In this wear rates are more dramatic as compared to the later one. The second one corresponds to material separation between two interfacing surfaces. It generally begins with excessive rubbing of the surfaces.

Now to make the choices, it is clear that for the first type of wear, harder material like ceramic coatings can be ideal and for the second one, softer stuff is useful. These coatings and sprays can be very effective to prevent the further damage and also enhances the life of the items.
