Metal Spraying Process is also known as thermal spraying involves covering a different range of covers with a metallic coating using a spray of molten particles. There are many spraying techniques flame spraying, wire arc spraying, plasma spray, detonation spraying, HVOF gun, warm spraying, cold spraying, and high-velocity air fuel.
The spraying technique is different factors including the application you are using, as well as your budget, operational timeframe, and preferred finish.
The metal spray process involves heating a material to the molten or semi-molten state and propelling it against the substrate to produce a suitably adherent coating.
There are five different methods for applying thermal spray metals:
Either oxygen/fuel combinations or a DC electric arc is only used to apply heat. Many coaters use the arc spray gun for applying adherent, fine-grained and non-porous coatings on the surface. The process allows little heat to the substrate – between 100 and 260 degrees Celsius. Because of this, metal spray can be applied to most substrates including metals, plastics, and composites, and to finished machined parts.
Although this technique is used across a number of different areas, it is mostly connected with the anti-corrosion and engineering markets where accuracy, quality, and durability are essential. With this in mind, you will quickly discover that this technique is used to add finishing coatings, create anti-corrosion layers and thermal barriers, as well as to optimize wear resistance.
