Restore Worn Components.
Return Critical Equipment to Service.
We combine HVOF, PTA, Arc Spray, weld restoration, machining and precision grinding in one engineering workflow. We analyze the wear mechanism, select the appropriate material system and restore the component to its target dimensions.

What Is the Failure Mode?
We Match the Surface System to the Damage Mechanism
Instead of forcing a technology onto a component, we select the process around wear, impact, temperature, corrosion and tolerance requirements.

Quality Assurance
Applying the Coating Is Not Enough. It Must Be Measured.
The inspection plan is defined by project requirements: dimensional control, coating thickness, hardness, surface roughness, metallography and final documentation.

Reverse Engineering & Remanufacturing
Is Your OEM Lead Time Too Long?
We measure and remanufacture critical components that are obsolete, undocumented or difficult to source. Where appropriate, wear zones can be upgraded with application-specific coating or hardfacing systems.
