The repair of high-value and in-demand components can be an effective method of reducing operations and maintenance/sustainment costs while reducing equipment downtime and increasing readiness. Many existing techniques either cannot be utilized due to tolerance control or bring increased risks and inspection to compensate.

REM’s ISF® Technology is capable of removing minor to moderate surface damage on components while simultaneously generating a lower roughness surface finish. The process requires no proprietary OEM drawings or expensive tooling and can typically be completed within a single shift. REM’s ISF® Process can controllably remove between 0.0001 – 0.003” (~2.5 – 76 µm) of surface material to eliminate or remediate numerous different types of surface damage including wear and corrosion.

Wind Turbine gears, flight-critical aerospace gears, and high-value turbine compressor blades are all proven applications for REM’s repair technology[1] [2] [3]all without detriment to the performance of the components.

REM’s ISF Process is a flexible technology allowing a range of component types and geometries to be processed without needing extensive programming or cumbersome set-up. Components that would otherwise not be able to be repaired (such as interference fit gear assemblies and nitrided components) can be repaired in REM’s ISF Process.

If you have a repair application that you believe REM could address with our technology or simply wish to learn more, please contact us today.
