For over one hundred years, companies have relied on technology to help improve the qualities of their components. For cost-effective protection against the elements and other damaging forces, they rely on finishing companies to imbue the items with a protective coating. For many a thermal spray coating is the most effective and efficient means of achieving this goal.
Types of Thermal Spray Processes
Coating is a process that involves overlaying the metal (or other material) substrate with a layer of protective and/or decorative particles. In order to apply these, a company can employ one of these four major thermal spray processes.
* Flame
* Arc
* Plasma
* High-velocity oxygen fuel (HVOF)
The energy source acts to propel the now heated material onto the surface of the substrate of the component.
Thermal Spray Benefits
A thermal spray coating has a specific intent. It is to cover the surface of the component. In doing so, it provides several benefits. Among them are:
* Protection: Depending upon the type of coating, it will imbue the surface with a resistance to chemical and rust corrosion. It may improve durability and increase longevity as well.
* Cost Reduction: Coatings can outlast the original material base. Coating is also a cost-efficient means as it is a repair rather than a replacement.
* Versatility: Thermal spray processes are capable of covering almost any type of material. It can coat metals, alloys, ceramics and even plastics.
* Thicknesses: Operators can choose to overlay a workpiece with thicknesses of up to one-inch
* Application Rate: Spray coating occurs quickly, easily and is efficient in the hands of the right operator using the best equipment.
Thermal Spray Coating
With increasing pressures on providing durable components, the demand for thermal spray coating will continue to rise. Finishing companies will strive to find greener and better technology. To match this, technology will continue to work to improve coating capabilities.
