HVOF
High velocity oxygen fuel spray coatings
At Hannecard, we are proud to offer advanced High Velocity Oxygen Fuel (HVOF) spray coating solutions for a wide range of industries, including steel, paper, and textile. In these sectors, where rollers and industrial parts are subjected to extreme conditions, ensuring the durability and performance of equipment is essential. HVOF spray coatings have become a leading technology for the enhancing of the lifespan and reliability of components by providing superior protection against wear, corrosion, and high temperatures. Our advanced HVOF coatings are specially designed to thrive in harsh operational environments ensuring your equipment remains efficient and long-lasting.
What is HVOF spray coating?
The HVOF process uses oxygen and fuel gas to form a combustible mixture. The heated powder material is propelled onto a surface at extremely high speeds through a gas stream. Particles impact the target surface with tremendous speed, creating a dense, durable coating that adheres to the substrate. The high velocity involved in the process ensures that the coating is characterized by minimal porosity, excellent bond strength, and high resistance to environmental stressors.

HVLF
High Velocity Liquid Fuel spray coatings
At Hannecard, we proudly offer HVLF spray coatings, an advanced thermal spray technology that provides exceptional protection for industrial components and rollers. HVLF coatings stand out for their superior wear resistance, corrosion protection, and long-term durability, making them an excellent choice for industries operating in extreme conditions. By utilizing high-velocity spraying combined with liquid fuel combustion, HVLF coatings deliver dense, high-quality surfaces that significantly extend the life and reliability of critical components.
What is HVLF spray coating?
The HVLF process uses liquid fuels, such as kerosene or diesel, which are burned to generate a high-energy gas stream. This gas stream accelerates metal, alloy, or carbide particles at extreme velocities, allowing for the creation of highly dense and well-bonded coatings. Compared to other thermal spray techniques, HVLF offers some unique advantages. While both HVLF and HVOF use high-velocity spraying to create dense coatings, HVLF operates at higher energy levels due to the use of liquid fuel. This results in a denser coating structure with even better bonding, making it more suitable for components exposed to extreme wear and stress. HVLF coatings tend to have higher energy due to liquid fuel combustion, resulting in coatings with greater density and mechanical strength, particularly for applications needing maximum durability.
