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.

HVAF
High velocity air fuel spray coatings
At Hannecard, we are proud to offer cutting-edge HVAF spray coatings, a state-of-the-art thermal spray process that provides rollers and industrial components exceptional protection. HVAF coatings are renowned for their superior wear resistance, corrosion protection, and durability, making them the perfect choice for the industries operating in harsh environments. By combining the high velocity of spraying with the lower combustion temperatures of air-fuel systems, our HVAF coatings deliver dense, high-quality surfaces that ensure long-lasting performance and enhanced reliability for critical industrial parts.
What is HVAF spray coating?
The HVAF process involves burning air and propane to create a high-speed gas stream. This gas stream accelerates metal, alloy, or carbide particles to supersonic speeds. HVAF operates at lower temperatures but higher speeds than HVOF, making it an optimal solution for certain materials with minimal oxidation and thermal stresses in the coating. This leads to the formation of dense, well-bonded coatings with superior mechanical properties, making HVAF ideal for the coating of industrial parts that require enhanced protection.
