Services

High-quality coatings can make all the difference in the performance and longevity of your components. That's why at Quality Carbide, we specialize in providing top-of-the-line High Velocity Oxy-Fuel (HVOF) spray services. Our advanced coatings offer superior protection against abrasion and corrosion, making them an ideal choice for different industries.

What is HVOF?

HVOF stands for High Velocity Oxy-Fuel, and it is a thermal spray coating process that uses a mixture of fuel gas and oxygen to produce a high-velocity flame. This flame is then used to heat and accelerate a stream of powdered material onto the surface of the substrate, where it melts and forms a coating.

At Quality Carbide, we use HVOF coatings to protect a wide range of substrates, including metals, ceramics, and plastics. Some of the common substrates that our HVOF coatings are applied to include steel, stainless steel, aluminum, titanium, nickel-based alloys, ceramics, and plastics.

Applications of HVOF coatings

HVOF coatings have a wide range of applications in different industries, including aerospace, automotive, oil and gas, and many others. Some of the common applications of HVOF coatings are:

• Wear resistance: HVOF coatings provide excellent wear resistance properties, making them ideal for applications that involve high-stress and abrasive environments.
• Corrosion resistance: HVOF coatings provide superior corrosion resistance properties, making them ideal for applications that involve exposure to harsh environments, such as saltwater.
• Thermal barrier coatings: HVOF coatings can be used as thermal barrier coatings in high-temperature environments, where they help to protect the substrate from thermal damage.
• Electrical conductivity: HVOF coatings can be used to provide electrical conductivity to non-conductive substrates, such as plastics and ceramics.

Quality and durability of HVOF coatings

HVOF coatings are known for their high-quality and durability. They produce a coating that is extremely dense and well-bonded to the substrate, which provides superior protection against abrasion and corrosion. Compared to other thermal spray coating methods, such as plasma spraying and flame spraying, HVOF coatings provide a higher density and bonding strength, making them more durable and resistant to wear and corrosion.

HVOF spraying process

The HVOF spraying process involves several steps, including:

1. Surface preparation: The substrate surface is prepared by cleaning, grit blasting, and/or roughening to provide a good surface for adhesion of the coating.
2. Coating material preparation: The coating material is prepared by mixing a powdered metal or ceramic material with a binder material to form a feedstock.
3. Feeding of the feedstock: The feedstock is fed into the HVOF spray gun, where it is heated and propelled towards the substrate surface using a mixture of fuel gas and oxygen.
4. Coating deposition: The heated and accelerated feedstock particles impact the substrate surface, where they melt and solidify, forming a dense and well-bonded coating.

Equipment used for HVOF spraying

The equipment used for HVOF spraying includes a spray gun, a fuel gas source, an oxygen source, and a powder feeder. The spray gun is designed to provide a high-velocity flame that accelerates the feedstock particles towards the substrate surface. The fuel gas source and oxygen source are used to produce the flame, while the powder feeder is used to feed the feedstock material into the spray gun. There are several types of spray guns used in HVOF spraying, including the DJ HVOF Gun, JP5000 HVOF Gun, and Diamond Jet HVOF Gun.

Safety considerations

There are several safety considerations that need to be taken into account during the HVOF coating process. The H

VOF process involves the use of high-pressure gases and high-temperature flames, which can be hazardous if proper safety precautions are not taken. Some of the safety considerations include:

1. Proper ventilation: The HVOF coating process produces hazardous gases, such as carbon monoxide and nitrogen oxides. Proper ventilation is essential to prevent the buildup of these gases in the work area.
2. Personal protective equipment (PPE): Workers who are involved in the HVOF coating process should wear appropriate PPE, such as gloves, goggles, and respirators, to protect themselves from the hazards associated with the process.
3. Equipment maintenance: The HVOF spray gun and other equipment used in the process should be properly maintained and inspected to prevent equipment failure, which can result in hazardous situations.

At Quality Carbide, we prioritize safety and take all necessary precautions during the HVOF coating process. Our team of experts is well-trained in using the equipment and following the safety protocols to ensure that the process is performed safely and efficiently.
