Surface Enhancement Technologies, LLC

Turnkey surface treatment processing customized to application requirements, deployable during manufacturing or maintenance either in-house or in-situ using CNC machine tools or robots.

• Low Plasticity Burnishing (LPB)

  A mechanical surface enhancement process using a CNC-controlled rolling contact tool to impart a deep, stable compressive residual stress field with minimal cold work.

• Controlled Plasticity Burnishing (CPB)

  A variation of LPB designed for applications where low cold work is not a primary requirement.

• Controlled Impact Burnishing (CIB)

  A process that treats vulnerable areas of a component with highly controlled impacts to impart beneficial compressive residual stress.

• Deep Rolling

  A traditional burnishing process where a tool is rolled across the surface with sufficient force to generate compressive residual stress.
