Why Should You Choose HVOF Coating For Your Equipment?
Industrial equipment is subjected to harsh environments, extreme temperatures and corrosive substances on a daily basis.
Naturally, this takes a toll on its performance and lifespan.
To overcome these challenges, industrial equipment requires robust and reliable coatings that can withstand these harsh environments and provide long-term protection.
Thermal spraying, or thermal coating, is a popular technique used to provide this kind of protection. There are several types of thermal coatings, including combustion powder spraying, arc spraying and HVOF coating.
HVOF (high-velocity oxygen fuel) is a thermal spray process that uses a high-velocity mixture of fuel gas and oxygen to heat and accelerate the coating material to supersonic speeds. The high-velocity particles are then sprayed onto the surface of the equipment, creating a dense and hard coating.
HVOF coating is one of the most effective thermal coatings. If you’re considering a coating for your industrial equipment, consider the unique properties HVOF has to offer:
HVOF produces a high-density coating
A high-density coating provides excellent protection against abrasion, erosion and cavitation, making it ideal for heavy-duty industrial equipment.
Low porosity
As a result, the HVOF coating produced has a very low porosity level, typically less than 1%. Porosity is significant to the coating’s protective capabilities. Low porosity means the coating is much less prone to wear and tear, and is also much more resistant to corrosion.
Hardness
The high-density coating produced by HVOF is also much harder than other types of thermal coatings. The high degree of particle deformation and compaction results in a dense, hard coating. The hardness of HVOF coatings is typically in the range of 800 to 1200 HV, which is significantly higher than other types of thermal coatings. While the high-density coating can protect the equipment from wear and tear, the hardness of the coating can provide additional protection against scratches and dents. This is ideal for equipment used in harsh environments.
HVOF coatings have a high bond strength
HVOF produces coatings with high bond strength. This is because the particles are accelerated to supersonic speeds using a high-pressure gas stream, which provides the particles with a high kinetic energy. When the particles strike the substrate, they deform and flatten, creating a strong mechanical bond between the coating and the substrate.
Durability and lifespan
High bond strength improves the overall durability and lifespan of the coated equipment. This strong bond ensures that the coating remains firmly attached to the substrate and is less likely to peel away or flake off. This makes HVOF coating ideal for equipment that is subjected to high stress or where the equipment is exposed to high levels of vibration or shock, such as machinery used in the mining or oil and gas industries.
High temperatures
The high bond strength of HVOF coatings also enables the coating to withstand high temperatures without degrading or breaking down. This is particularly important for equipment that operates at high temperatures, such as gas turbines, boilers and exhaust systems. The high bond strength ensures the coating remains firmly attached to the substrate, even when exposed to extreme temperatures, protecting the equipment from corrosion and wear.
Wide range of substrates
HVOF coatings create excellent adhesion to a wide range of substrates, including metals, ceramics and composites. This versatility makes HVOF coating suitable for a variety of industrial applications, where equipment is made from different materials.
In HVOF coatings, the strong mechanical bond between the coating and the substrate ensures that the coating remains firmly attached, providing long-term protection against wear, corrosion and degradation. This makes HVOF coating an excellent choice for industrial equipment that requires long-term protection and durability.
HVOF is a versatile coating
HVOF coatings can be applied to a wide range of substrates, including metals and alloys, which makes them suitable for a variety of industrial applications.
Customisable
HVOF coatings can be customised to the specific requirements of different applications. They can be tailored to provide enhanced wear resistance, corrosion resistance or thermal insulation. This flexibility allows HVOF coatings to be used in a wide range of industries, including aerospace, automotive and manufacturing.
Repairs
HVOF coatings can also be used to repair or refurbish worn or damaged parts. The coating can be applied to the damaged area, restoring the part to its original condition. This is a cost-effective and convenient alternative to replacing the part.
Complex shapes and surfaces
In addition, HVOF coatings can be applied to large and complex shapes and surfaces. This is because the spraying process is highly controllable, allowing for precise and even application of the coating. This is great for parts with complex geometries, such as turbine blades or engine components.
The versatility of HVOF coating makes it a highly desirable option for industrial applications. Its ability to be applied to a wide range of substrates, customised for specific needs and repair worn parts, makes it a valuable addition to any industrial machinery.
