HVOF/HVAF Thermal Spray Powders
High-Density Coatings. High-Performance Protection.
High Velocity Oxy-Fuel (HVOF) and High Velocity Air-Fuel (HVAF) thermal spray processes produce dense, low-porosity coatings with exceptional mechanical bond strength and surface integrity. Wall Colmonoy’s HVOF and HVAF powders are engineered to meet the stringent performance requirements of industries that demand maximum wear, corrosion, and erosion resistance under extreme operating conditions.
These advanced coating methods are ideal for enhancing the durability of components within the oil & gas sectors such as pump sleeves, valves, and downhole tools; mining components such as slurry pumps, hydraulic rods, and pistons; power gen components such as gas turbine blades, nozzles, and fans; pulp & paper roll components; steel guides, rolls, and dies.
Products for HVOF & HVAF Applications
Wall Colmonoy’s Colmonoy® (nickel), Wallex® (cobalt), and WallCarb™ HVOF and HVAF powders features tungsten carbide, chromium carbide, and custom matrix options for maximum protection in high-stress environments. These powders deliver exceptionally hard, wear-resistant coatings with minimal porosity – ideal for industries such as oil & gas, power generation, mining, rubber & plastics, aerospace, and heavy manufacturing.
Available in a range of particle size distributions and chemistries, our powders are engineered for excellent flow characteristics, strong adhesion, and long-term performance under thermal and mechanical stress.
