Thermal Spray Coatings
HVOF Thermal Spray Roll Services
Thermal spray processes are a type of surfacing technology used to protect an extensive range of industrial components and equipment. Depending on your project, goals, and selected OEM thermal spray specifications, these coating processes create resistance to wear, corrosion, high temperatures, chemicals, exposed environments, and multiple types of wear. Additionally, thermal spray processing will rebuild worn areas back to OEM dimensions, allowing for component and print assembly.

Thermal Spray Coating Processes
Hannecard – ASB has the expertise to apply coatings to nearly any substrate. No thermal spray process is outside our capabilities, enabling us to offer specialized thermal spray coatings that improve equipment performance, boost wear and corrosion resistance, extend component life, and more. Typical thermal spray coating services include:
Plasma Arc Spraying
Plasma Arc spray coatings creates a hard coating surface that protects substrates against wear, oxidation and corrosion wear caused by environmental and operating conditions. The coatings are dense and strong, making plasma spray coating a favorable option for equipment protection and refinishing.
High-Velocity Processes (HVOF Coatings)
The HVOF (High Velocity Oxygen Fuel) coating process combines supersonic particle impact on the substrate with controlled heat energy to produce a consistent hard-particle surface distribution with high bond strengths, low porosity, and high wear resistance.
Electric Wire Arc Spraying
Electric arc results in a spray process that is economically efficient to produce effective results, with very little heat transferred to the workpiece. Additionally, electric arc wire spraying produces spray at higher spray rates than other thermal spray processes, creating some of the fastest coating rates of any coating method.
Cold Spray
With high-pressure cold spray, coating materials aren't melted by a thermal energy source. Instead, energy from high-pressure gas allows injected powder material to reach critical velocity. The cold spray coating process utilizes supersonic nitrogen and/or helium gas jet that propels solid powder particles onto the workpiece at speeds as high as Mach 3 (900 m/s) to create both build up and surfacing layers. As a result, the particles form a strong and dense bond to the substrate.
Combustion Flame Thermal Spray Coatings
Flame spray coating is an all-encompassing term for a number of thermal spray processes. As the name implies, a high-temperature flame transforms the coating materials into a semi-molten state; this molten material is then sprayed onto the workpiece to form a surface coating.

What are Applications of Thermal Spray Coatings?
Rebuilding of Mis-Machined Component
Initially developed in the late nineteenth century as a metallizing process, thermal spray methods have evolved over the past century to include other materials and apply to many different substrates. Today, this technology is widely used across industries, including aerospace, automotive, energy, steel, biomedical, and many others. Common thermal spray coating applications include:
- Coating turbine blades to improve wear resistance and extend lifespans
- Applying thermal barrier coatings to gas turbine components for enhanced efficiency
- Depositing biocompatible coatings on medical implants to reduce the risk of rejection
- Custom thermal spray finishes for specialized requirements
- And many more!
Consult With One of Our Thermal Spray Experts
While thermal sprays can serve a multitude of options for many OEMs and manufacturers, sometimes inherent properties are not the best solution for all applications. Certain part shapes and sizes are suitable for thermal spray coating technologies due to achieving optimal coating angles. Many time extreme heat or high forces—which may be a possible option for welding that HRC/ASB can offer. Additionally, some requirements for thick coating which may weaken properties and impact the overall performance of components.
If thermal spray technology is not right for your application, cold spray coatings and other protective surfacing methods are available to match your requirements. Consult with a surfacing technology expert to find your best solution.
