Common
Thermal Spray Applications
Thermal spray coatings are used throughout many industries, from chemical, to power generation, to
steel production to semiconductor.
New applications are constantly developed.
Below lists general areas where thermal spray may be of
significant benefit…
~ Replacement of chrome plating using tungsten carbide thermal spray
~ Life cycle improvements where wear and corrosion lessen the life of your equipment
~ Restoration/ repair of old/ worn components or equipment.
Some common items repaired include…
- Process Rolls
- Shafts
- Valve Components

What is thermal spraying?
Basically, thermal spraying is when a coating material (in powder, rod or wire form) is heated to a designated temperature and then propelled in a molten state onto a substrate. The result is a mechanically bonded coating that will restore size or protect the substrate in the application.
It’s amazing that the thermal spray process, initially developed over 100 years ago in Switzerland by Max Ulrich Schoop, today uses technology that can spray coatings at supersonic speeds!
This unique ‘One Source’ capability offers you high quality, timely manufacturing and repair service without the hassle of multiple vendors and blurred lines of responsibility.

How are thermal spray coatings applied?
HFW remains at the forefront of thermal spray technology by using state-of-the-art equipment, including robotics, with our 25 plus thermal spray systems.
The process chosen is based on what is best for each application. That may depend on the material to be sprayed, the substrate and the result desired. HFW has in-house laboratory facilities to qualify and test coatings to customer required specifications.
Thermal spray processes we perform in-house include:
– High Velocity Oxy-Fuel or HVOF Coatings (pictured above)- dense metal/ carbide coatings
– Plasma Coatings- metal, ceramic and cermet coatings
– Sprayweld Coatings- metal alloys fused to the substrate
– Rokide Coatings- select ceramic coatings
– Metallize Coatings- metal coatings by wire or powder processes
HFW can apply any material that does not decompose as it is melted. These materials include pure metals, ceramics, cermets and polymers.

Application Example
(Vacuum Pump)
* After pump disassembly and cleaning our scope was as follows…
* Shaft and Rotor Assembly- Machine drive, seal and packing sleeve diameters and machine to prepare cone fits of rotor for coating. Thermal spray with Hastelloy C and finish.
* Cones- Thermal spray with Hastelloy C and finish grind to assure proper fit with rotor.
* Heads- Pressure test, machine inboard face and pilot diameter for coating and thermal spray with Hastelloy C and finish.
* Assembly- Assemble complete including bearings, seals, gaskets and packing along with dynamic balancing and painting as required.
The results?
Life of the pump
increased from 9-18 months to 5 years!

Thermal spraying includes a variety of processes where molten material is propelled onto a substrate. The two surfaces form a mechanical bond and the substrate temperature generally remains below 300 degrees fahrenheit so zero distortion occurs.
The thermal spray process is used for the purpose of restoring component size to OEM dimensions, and extending service life through enhancing resistance to abrasion, wear, heat and corrosion, among others. The results are lower maintenance costs and increased uptime for our customers!
Additional benefits to thermal spraying include:
- Components can be re-engineered using higher performance materials
- Wear is prevented or retarded
- Improved functionality and life of process-related or OEM equipment
- Improved lead time—repairing components vs. manufacturing
- Obsolete parts no longer available from the OEM are able to be repaired/salvaged
