Thermal Spray process

Thermal Spraying

Thermal spraying, which includes Flame Spray, Arc Spray, Plasma Spray and more, involves coating surfaces with melted materials to repair, protect, and enhance them. It is used in the construction industry, electronic industry, and aerospace industry. It can also be used to improve and modify the surface of solid objects. These are five benefits and advantages of using thermal spraying for surface coating.

Provides Durability for Substrates

Thermal spray coatings give a longer life span to the surfaces they are applied to as it provides a thick layer for objects. Due to the thickness range it allows, which is usually 100 to 750 microns, it offers resistance to wear and tear cavitation, corrosion, abrasion, and erosion. It can also be used to create thermal barriers and electrical conductivity.

The flame spray coating from zinc and aluminium can be used on gates, fences, and steel in bridges to prevent corrosion. Almost all the thermal spray processes such as plasma arc spraying can be used for the same purpose. It goes a long way to extend the object's lifespan and performance.


One of the things driving the thermal spray coating market is the procedure's cost-effectiveness. Compared to the cost of buying other machinery and using thermal spraying, the thermal spray coating lasts longer than the original layer of product surfaces. It is excellent for repairing holes, scratches, and damages on object surfaces and generally for repairing and rebuilding the components of a machine or metals. There have been reports and records of a growing demand for thermal spray coated fragments in many industries, including healthcare, due to this advantage.

Wide Variety of Coating Substances

When it comes to the material to be used for thermal spray coating, there is a wide range on the market. Thermal spraying usage is not limited to a particular metal or surface. Therefore, an engineer is presented with different coating material choices when working on an object that needs to be repaired or modified.

Wide Variety of Substrates

Several kinds of metals including steel, copper, alloy, and bronze, can be coated using thermal spraying. Other substrate materials such as ceramics, plastics, and glass can also be thermally sprayed. Almost any coating material can be applied to many metal substrates and plastics. It is the perfect solution for various objects with corrosion, cavitation, and abrasion.

Heat Is Not Required for Use on Substrates

With other metal spraying types, heat is applied to the substrate material to bond with the coating. This procedure is likely to change the form of the substrate material it is used on. But the thermal spray method, on the other hand, releases very little heat to the substrate object. Due to this, there is practically no danger of the item deforming or bending, as it frequently happens in the case of other welded coatings. Consequently, thermal spray coatings can be applied to finished products or machinery.

There is a growing demand for thermal spray coated parts in the engineering industry due to its effectiveness, durability, and low cost. Contact a thermal spraying professional such as Metallisation to get your products layered and repaired for a longer span of usage.
